and
34
.
No internal or external adjustments are required to use any of the voltages included in the two
indicated intervals.
For the external protection, IPR-D has no internal fuses.
2.9 SYSTEM
GROUNDING
On the rear side of the relay there are two separate grounds [
Æ
Fig. 2.2]:
•
Internal metal chassis parts and external shield safety ground terminal
...................................................................
31
•
Surge suppression components ground terminal (grounded to separate filter ground)
.........................................
33
For reliable operation both grounds must be connected directly to the ground bus bars of the switchgear. Do not
connect the ground connection to the switchgear metal frame because low impedance to ground cannot be
guaranteed.
2.10 HIPOT
TESTING
Hipot testing carried out by the Manufacturer:
•
Voltage
.........................................................................................................................................................
2000 Vac, 50 Hz
•
Time (under voltage)
...............................................................................................................................................
1 minute
Disconnect the communication terminals and filter ground during dielectric strength testing (hipot) or
damages to the internal surge protection devices may occur.
If hipot testing is to be performed on an installed relay for insulation verification, all remaining terminals except for:
•
Safety ground te external shield
.........................................................................................................................
31
•
Surge suppression components ground terminal (grounded to separate filter ground)
.........................................
33
should be connected in parallel.
