If in doubt, about its safe usage, the unit must be put out of service to prevent any accidental use.

You must assume that safe usage is impossible if:

1. the unit shows visible signs of damage.

2. the unit does not function (for example with autotest or with the trip test unit).

3. the unit has been damaged in transit.

WARNING: Prior to servicing and/or replacing, the circuit-breaker must be open.

Also remember to disconnect all power supplies connected.

11.1.1. Notes for dielectric stiffness tests

WARNING: Dielectric stiffness tests on the releases, inputs and outputs, are not permitted.

Relè also called “protection unit” or “protection release”

RMS Root mean square value

TC Trip Coil (opening solenoid)

SdZ Zone selectivity

UI/O External toroid (SGR)

SW Software

i-Test "i-Test" button on the front of relay

Trip CB opening, generated by the release

11.2.2. Notes

A. Use the “Belden 3105A”- type two-wire cable for instance (not supplied by ABB SACE).

B. Use the “Belden 3106A”- type three-wire cable for instance (not supplied by ABB SACE).

C. The unit has a “backup-protection” function; if the first command to the opening solenoid does not open immediately the circuit-

breaker (TC partially fault), TRIP commands are repeatedly sent until the circuit-breaker opens (providing a Vaux is present) or

the current disappears (if self-power supplied). The “backup” condition can be signalled by configuring the unit relays; using

the “YO back” selection, it is possible to command the “opening coil(YO)” accessory as another opening device if TC does

not work.
