Connecting metering panel to high voltage

Fig. 51: Cable connection in metering panel
For the exact panel dimensions, such as the cable connection height, please refer to the
dimension drawing and arrangement diagram of the switchgear.
Connect the voltage transformer's primary to the cable termination at the desired
point.
Check the tightening torque (37 lbf·ft or 50 Nm) of the bolted joint between the cable
and the block-type current and/or voltage transformers.
Bolt terminated cable to the cable connection terminal and avoid undue strain on
bushing. For the tightening torques of the cable lugs / cable terminations, please
observe the manufacturer's instructions, however do not exceed 37 lbf·ft (50 Nm).
