ISOLATION TEST

IMPORTANT:
During all tests, the screw located on the rear of the relay must be grounded.
For verifying isolation, independent groups will be created, and voltage will be applied as follows:
2500 RMS volts will be applied progressively among all terminals in a group, short-circuited between them
and the case, during one second. In case the Hi-Pot device used to test the relay trips due to excessive
consumption, apply the test between each group and ground one at a time.
2500 RMS volts will be applied progressively between groups, during one second.
Group 1 (LATCHING RELAY contacts): A5 – A6 – A7 – A8– A9 – A10 – A11 – A12– B1 – B2– B3 – B4– B5 –
Group 2 (LATCHING RELAY coils):
Group 3 (Pushbutton):
Group 4 (Analog Group):
Consumption will not be higher than 20 mA.
