the this interface.

The ECL‑600 Series are compatible with the IO Extension Module product line, which includes the following modules: ECx‑400, ECx‑410, and ECx-420

(refer to the ECx‑400 series IO Extension Module Hardware Installation Guide).

Each controller uses the LONWORKS TP/FT-10 communication protocol.

This document describes the hardware installation procedures for the following controllers: ECL‑203, ECL‑300, ECL‑400 Series, and ECL‑600 Series

controllers only.

£These controllers are all built on a similar platform, but have different numbers of inputs and outputs. Moreover,

each individual model has different amounts of digital and/or universal outputs. For more information on the

specific layout and functionality of each controller, please refer to their individual datasheets.

£The following controllers are housed in small enclosures: ECL‑203 Series and ECL‑300 Series.

£The following controllers are housed in large enclosures: ECL‑400 Series and ECL‑600 Series.

General Installation Requirements

For proper installation and subsequent operation of the device, pay special attention to the following recommendations:

£It is recommended that the controller(s) be kept at room temperature for at least 24 hours before installation to allow any condensation that may

have accumulated due to low temperature during shipping/storage to evaporate.

£Upon unpacking, inspect the contents of the carton for shipping damages. Do not install a damaged device.

£The device is designed to operate under environmental conditions that are specified in its datasheet.

£Ensure proper ventilation of the device and avoid areas where corroding, deteriorating or explosive vapors, fumes or gases may be present.

£Record the 12-character Neuron® ID located on either end of the device (shown on a sticker below the barcode), for later commissioning.

£Allow for proper clearance around the device’s enclosure and wiring terminals to provide easy access for hardware configuration and maintenance.

£When installing in an enclosure, select one that provides sufficient surface area to dissipate any heat generated by the device and by any other de-

vices installed in the enclosure. A metal enclosure is preferred. If necessary, provide active cooling for the enclosure.

£Orient the controller with the ventilation slots and power supply/output terminal block connectors towards the top to permit proper heat dissipation.

£The device’s plastic enclosure has a back plate that is separable from the front plate allowing the back plates (with the connectors) to be shipped di-

rectly to the installation site while all the engineering is done in the office.

£The device’s datasheet specifies the power consumption (amount of heat generated), the operating temperature range, and other environmental

conditions the device is designed to operate under.

£Ensure that all equipment is installed according to local, regional, and national regulations.

£Do not drop the device or subject it to physical shock.

£If the device is used and/or installed in a manner not specified by Distech Controls, the functionality and the protection provided by the device may

be impaired.

Installation Guide

2 / 16

Any type of modification to any Distech Controls product will void the product’s warranty

Take special care to keep the front and back plate aligned when separating and joining them.

Before installation of the Wireless Receiver, verify that local communication regulations allow the installation of wireless devices and

available frequencies to be supported in your area. Refer to the Open-to-Wireless™ Application Guide for more information.

Take reasonable precautions to prevent electrostatic discharge to the device when installing, servicing or during operation. Discharge

accumulated static electricity by touching one’s hand to a well-grounded object before working with the device.

Device Markings (Symbols)

Certain markings (symbols) can be found on the controller and are defined as follows:

General Wiring Recommendations

Risk of Electric Shock: Turn off power before any kind of servicing to avoid electric shock.

£All wiring must comply with electrical wiring diagrams as well as national and local electrical codes.

£To connect the wiring to a device, use the terminal connectors. Use a small flat screwdriver to tighten the terminal connector screws once the wires

have been inserted (strip length: 0.25’’ (6mm), maximum tightening torque 0.5 Nm).

£Comply with all network and power supply guidelines outlined in the Network Guide.

£Always use unshielded cabling with a minimum Category 5 (CAT5) cable for ethernet communications.

£Keep wiring separate according to their function and purpose to avoid any ambient noise transmission to other wires. Use strapping to keep these

wires separated. For example, keep power, hazardous voltage, SELV, PELV, network, and input wiring separate from each other.

£The board connectors accept wires or flat cables ranging from 22 to 14AWG (0.644 to 1.630mm diameter) per pole. However, power cables must be

between 18 and 14AWG (1.024 to 1.630mm diameter).

£Keep all wires away from high speed data transmission cables (for example, Ethernet, etc.).

£Do not connect the universal inputs, analog/digital outputs or common terminals to earth or chassis ground (unless stated otherwise).

£Keep input and output wiring in conduits, trays or close to the building frame if possible.

Mounting Instructions

The controllers can be mounted on a DIN rail to speed up the installation procedure. They are also equipped with two mounting holes 0.25” x

0.165” (6.35mm x 4.191mm). The controllers can be mounted in a panel or on a wall by using appropriate screw types (use sheet metal, thread forming,

or self-tapping screws accordingly).

The controller’s mounting orientation must be horizontal with controller’s back attached to a vertical wall surface.

Figure5: Permitted Mounting Positions

DIN Rail-Mounted Installation

1. Ensure the DIN rail is properly mounted on the wall.

2. Simply clip controller onto the DIN rail.

Wall-Mounted Installation

Power Wiring

Voltage: 24VAC/DC; ± 15%, Class 2

This is a Class 2 Product. Use a Class 2 transformer only (rated at 100VA or less at 24VAC) to power the

controller(s).

The Network Guide provides extensive information and requirements for powering a controller that uses a LONWORKS network for communications. It can

be downloaded from our website.

It is recommended to wire only one controller per 24VAC transformer.

If only one 24VAC transformer is available, determine the maximum number of controllers that can be supplied using the following method to determine

the required power transformer capacity:

£Add up the maximum power consumption of all controllers including external loads and multiply this sum by 1.3.

£If the resulting number is higher than 100VA, use multiple transformers.

Use an external fuse on the 24VAC side (secondary side) of the transformer, as shown below, to protect all controllers against power line spikes.

Maintain consistent polarity when connecting controllers and devices to the transformer. That is, the COM terminal of each controller and each peripheral

should be connected to the same terminal on the secondary side of the transformer.

Connecting the power source to Electrical System Ground is not a requirement for proper system operation. However

it is good installation practice to do so in order to maintain the same potential between all controllers and Protective

Earth.

Always use a separate transformer for each ECL-600 series controller and for each of its associated IO Extension

Module (ECx‑400s).

One terminal on the secondary side of each of these transformers must be connected to the building’s ground and to

the respective controller’s or IO Extension Modules’ 24V COM terminal.

Failure to maintain consistent polarity throughout the entire network will result in a short circuit and/or damage to the

controller!

The COM terminals of the controller are internally wired to the 24V COM terminal of the power supply. Connecting a

peripheral or another controller to the same transformer without maintaining polarity between these devices will

cause a short circuit.

Subnet-Wiring

The subnet is used to connect a range of Allure Series Communicating Sensors:

£The Allure EC-Smart-Vue Series sensor is a communicating room temperature sensor with backlit display graphical menus and VAV balancing ca-

pabilities.

£The Allure EC-Smart-Comfort and Allure EC-Smart-Air Communicating Sensors are a range of communicating room temperature sensors.

Connect the Allure Series to the controller’s Subnet Port with a standard Category 5e Ethernet patch cable fitted with RJ-45 connectors. Refer to the Net-

work Guide for extensive information and requirements for the connection of the Allure Series. It contains information about network topology and length,

cable type, setting the Subnet ID, etc. It can be downloaded from the

www.distech-controls.com

website. See also the Hardware Installation Guide sup-

plied with the Allure Series.

If you make your own patch cable, see the Allure Series Hardware Installation Guide.

Protect the controller’s connector from being pulled on when a cable to the Allure Series is connected. Create a

strain-relief by looping the cable and attaching it to a solid object with a nylon tie so that a tug on the cable will not

pull out the connector on the controller.

Subnet Wiring with the ECL‑600 Series Controller

ECx-400 series IO Extension Modules are connected to the SUBNET– and SUBNET+ terminals of the ECL‑600 series controller. The Network Guide

provides extensive information and requirements to implement the subnetwork for the ECx-400 series IO Extension Modules. It contains information

about network length, cable type, controller addressing, etc. It can be downloaded from our website. See also the Hardware Installation Guide supplied

with the ECx-400 series IO Extension Module.

Communications Wiring

The recommended cable type for LONWORKS® communications is 22AWG (0.65 mm), twisted pair, unshielded. The LONWORKS communication wire is po-

larity insensitive and can be laid out in a bus, star, loop or free topology. For loop topology, polarity is important, special care must be taken when con-

necting the LONWORKS network to avoid short circuit.

It is recommended to use the bus topology network configuration for all LONWORKS communication wiring, as it allows

for easy network troubleshooting.

Connect both wires to the LON+ and LON‑ terminals of the controller. If inserting multiple wires in the terminals, ensure to properly twist wires together

prior to inserting them in the terminal connectors.
