ACCEPTANCE TESTS
4.4
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 –
B6 – B7 – B8
Group 2 (LATCHING RELAY coils):
A1 – A4 – B9 – B12
Group 3 (Pushbutton):
C5 – C6 – C7 – C8
Group 4 (Analog Group):
C10 – C11 – C12 – D6 – D7 – D8 – D2 – D3 – D4
Consumption will not be higher than 20 mA.
