PTS 400.3 PLUS Operation Manual_R02 Page 252/306
Connections to test terminals
Use the delivered adapter pins and cables or if available special adapters and cables delivered with
the test terminals for the connections to the PTS 400.3 PLUS.
Attention! The current transformers must be short connected on the secondary side
during the time the current connections to the meter are changed to the PTS 400.3
PLUS.
The voltage paths from voltage transformers to the meter must be interrupted, before
making the connections between test terminals and PTS 400.3 PLUS voltage outputs.
Regard the instructions for the use of the installed test terminals and observe local
safety regulations.
Warning! The current path on secondary side of an active current transformer must al-
ways remain closed. Dangerous high voltages can occur and the current transformer
and the instrument can be damaged, if the current path is opened during measure-
ments.
