3 Safety Instructions

Finger guards t over the soft starter power terminals to

increase IP rating and prevent accidental contact with live

terminals.

WARNING

ELECTRICAL SHOCK HAZARD

VLT

Soft Starters contain dangerous voltages when

connected to mains voltage.

Models MCD5-0360C ~ MCD5-1600C: The bus bar and heat

sink are live while the unit operates (starts, runs, or stops). If

the soft starter is installed without a main contactor, the bus

bar and heat sink are live whenever mains voltage is

connected. This is also the case when the soft starter is

ready or tripped.

Improper installation of the motor or the soft starter, and

installing or servicing with power connected, can cause

death, serious injury, or equipment failure.

To avoid death, serious injury, or equipment failure:

•

Only use qualied electricians for carrying out the

electrical installation.

•

Disconnect the soft starter from all power sources

before installation or service.

•

Fit nger guards to all terminals, even if no cable is

connected.

•

Treat the bus bar and heat sink as live whenever

the unit has mains voltage connected. Also take

this precaution when the soft starter is tripped or

waiting for a command.

•

Follow the guidelines in these instructions and local

electrical safety codes.

4 Installation

4.1 IP20 Protection for MCD 200, MCD5-0131B

~ MCD5-0215B, and MCD5-0245C

MCD 200 and MCD 500 (enclosure sizes G2 and G3C) models

use rubber nger guards. Rubber nger guards provide IP20

protection when used with cable of diameter 22 mm or

greater.

Installation

1. Place 3 nger guards side by side in 1 retaining

bracket. Align the assembly so that the screw holes

in the bracket match the screw holes in the soft

starter.

MCD 200 only: Remove the 2 top screws from the

casing around the power terminals.

MCD 500 G3C enclosure size models only: Fit the

nger guard base chassis to the MCD 500 enclosure

rst before installing rubber nger guards.

2. Feed each power cable through the narrow end of

each nger guard. Connect the cables to the

appropriate terminals on the soft starter.

3. If the cables do not t through the nger guards,

shorten the nger guards at the narrow end to make

a bigger opening.

4. Screw the retaining bracket to the soft starter.

MCD 200 only: Use the screws from step 1 to attach

the retaining bracket to the soft starter casing.

MCD 500 G3C enclosure size models only: Fit the

nger guard cover over the nger guard base chassis

to complete the arrangement.

5. Repeat steps 1–4 for the other set of terminals.

4.2 IP20 Protection for MCD5-0245B ~

MCD5-0961B

MCD 500 (enclosure sizes G3B and G4B) models use rubber

nger guards. Rubber nger guards provide IP20 protection

when used with cable of diameter 22 mm or greater.

Installation

1. MCD5-0245B ~ MCD5-0396B: Screw the nger guard

plate to the base of the soft starter.

MCD5-0469B ~ MCD5-0961B: Screw the nger guard

bracket to the enclosure of the soft starter.

2. Fit 1 polycarbonate retaining bracket over each nger

guard.

3. Feed each power cable through the narrow end of

each nger guard. Connect the cables to the

appropriate terminals on the soft starter.

4. If the cables do not t through the nger guards,

shorten the nger guards at the narrow end to make

a bigger opening.

5. Screw each retaining bracket to the nger guard

plate/bracket.

4.3 IP20 Protection for MCD5-360C ~

MCD5-1600C

MCD 500 enclosure sizes G4C and G5C use nger guard

chassis enclosures to isolate live bus bars.

NOTICE

Each kit is only sucient for protection of either top or

bottom cable terminals. If both top and bottom cable

termination is used, 2 nger guard kits are required.

Installation

1. Fasten the nger guard base chassis to the main

enclosure of the soft starter using the screws

provided.

2. Drill power cable access holes into the gland plate

using the pilot holes provided. To prevent excessive

heating of the gland plate due to large eddy

currents, cut horizontal slits between the power cable

holes drilled into the gland plate.

3. Fit the gland plate to the nger guard base chassis

using the screws provided.

4. Run the power cables through the holes in the gland

plate and connect to the appropriate bus bar

terminals of the soft starter. To prevent fraying of

cables against the gland plate, t cable bushes or

glands (not supplied) appropriate for the size of

cable used.

5. Fit the nger guard cover over the nger guard base

chassis to complete the arrangement.

6. Repeat steps 1–5 for the other set of terminals.
