Bender PEM353 User manual

Universal measuring device

This quick-start guide does not replace the operating manual. The

manual is available in the download area of our homepage

(https://www.bender.de/en/service-support/downloads).

Make sure that the personnel has read the operating manual and un-

derstood all instructions relating to safety.

Scope of delivery

1 x PEM353, 1 x rubber seal, 4 x retaining clips, 1 x safety instructions

for Bender products (multilingual), 1 x quick-start guide

Intended use

The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective versions as TN, TT and IT

systems. The current measurement inputs of the PEM353 are always connected via external …/1A or …/5A

measuring current transformers. In principle, measurements in medium and high-voltage systems are car-

ried out via voltage transformers.

Use for the intended purpose also includes:



Device-specific settings compliant with local equipment and operating conditions



Adhering to the manual

Any other use than that described in this manual is regarded as improper.

Safety instructions

Installation

Risk of fatal injury due to electric shock!

Touching live parts of the system carries the risk of an electric shock, damage to the electrical installation

or destruction of the device.

Before installing and connecting the device, make sure that the installation has been de-energised.

Observe the rules for working on electrical installations.

Refer to the rated and supply voltage values as specified in the technical data!

Mounting in a front panel

Mounting opening 92 mm x 92 mm (max. 92.8 x 92.8 mm).

1. Mount the rubber seal on the back of the device.

2. Insert the device into the mounting opening of the front panel.

3. Place the four retaining clips over the device corners from behind.

4. Push the retaining clips tightly against the front plate.

5. Check the device to ensure that it is firmly installed.

The device is installed.

No. Connections

1Measuring voltage inputs: The measuring leads should be protected with 2 A fuses.

2Supply voltage: Power protection by a 6 A fuse, quick response.

If being supplied from an IT system, both lines have to be protected by a fuse.

3Measuring current inputs I4(PEM353-N only)

4RS-485 bus connection; Up to 32 devices can be connected to the bus.

The maximum cable length for the bus connection of all devices is 1200 m.

4 Digital inputs, galvanically isolated, 24 V;

An external circuit providing at least a current Imin of 1 mA is

required for triggering the inputs.

Connection diagrams

Connect the device according to the connection diagram. Please observe the technical data.

Measuring current inputs I1…3

Current measurement inputs must not be "protected" by fuses. Provide a shorting block for each

current measurement input as described in IEC 60364-5-55 (edition 2.2) chapter 557.5.3 (wiring

diagrams: disconnect terminal of the measuring current transformers "Y").

The current measurement inputs must not be earthed in low-voltage applications.
