1 Installation When installing the interference filter in the 3WL circuit-breaker, all instructions in Chapters 2 and 3 must be observed. 1 Switch circuit-breaker to the disconnected position (drawout circuit- breakers only). 2 De-energize the circuit-breaker. 3 Prepare for installation. See Chapter 2. 4 Remove the front panel. See Chapter 2.1.2. 5 Remove the overcurrent release. See Chapter 3.1. 6 Place the EMC filter in the space provided in the ...

7 Attach the yellow-green grounding cable to X100 with the cable lug on the enclosure of the electronic overcurrent release by means of the screw/nut provided. 8 Remove the -X20 connector and, if applicable, the -X24 nconnector from the overcurrent release. Plug the EMC filter into the -X20 con- nector and, if applicable, into the -X24 connector of the overcurrent release. 9 Loosen the cable ties on the circuit-breaker's transformer cable har- ness ...

10 Remove the cable duct cover. Pull the loose -X20 connector of the transformer cable harness into the cable duct. Lay the input (current sensor) cables of the EMC filter in the cable duct. Connect the -X20 plug-in connector of the transformer cable harness to the -X20a plug-in connector of the EMC filter. Secure the cables with cable ties. 11 Replace the cable duct cover. 12 Attach the mounting plate to the left of the circuit-breaker housing nex ...

2 Maintenance The arc chutes and the contact system must be inspected accord- ing to the operating conditions. Before closing again their condition must especially be checked after a short-circuit breaking operation. The slot with the arc-chamber cover must be replaced at the latest after the circuit-breaker has completed 3 short-circuit breaking oper- ations. The arc chutes and the contact system must be replaced depending upon their condition, a ...

Installation Installation is done in reverse order. If an overcurrent release with another configuration than the exist- ing one is installed, the order No. on the type label of the cir- cuit-breaker must be changed according to the catalogue data. The results of the test have to be documented. For that reason the “Announcement of circuit-breaker modification” form should be used. This form can be copied from the end of these operating instruct ...

3.2 Test device The hand-held test device is used to verify the proper operation of the overcurrent release, the energy transformers and current trans- formers as well as the F5 tripping solenoid and the data display. 3.2.1 View 1 LED for operating voltage indication 2 Control buttons 3 6 LEDs to show test results 3.2.2 Preparations - Switch off and isolate the circuit-breaker - Note the setting values of the overcurrent release - Switch off the ...

3.2.5 Operation The status test starts immediately after connecting the voltage sup- ply and queries the various components and parameters of the overcurrent release. If the status test is succesful, the "ETU STA- TUS" LED will light up. Otherwise, the "ETU STATUS" LED will flash. It is possible to draw conclusions about the fault cause from the way in which it flashes. The status test can be repeated any time by pressing the "START" button for at ...

Result of neutral CT check (for ETU release 2) A flashing light (1 second on, 1 second off) indicates an error in the area of the transducer of the neutral conductor. The cause of this will either be a missing transducer (e.g. no external neutral CT con- nected), a missing connection to the transducer or a faulty trans- ducer. A rapid flashing light (0.5 seconds on, 0.5 seconds off) indicates an error in the area of the energy transformer of the ne ...
