Installation Instructions
CAUTION
Installation and maintenance of the switchboard meter should only be performed by qualified personnel
who have appropriate training and experience with high voltage and high current devices.
If the switchboard case is included with your meter, draw the meter chassis out of
the case to facilitate its installation into the mounting hole. Installing and setting
up the switchboard meter is summarized in the following steps.
1. Review the unit’s dimensions and prepare a mounting hole for the
switchboard case. If you are retrofitting your switchboard meter into an
existing case, you may have to drill or punch a 29mm (1.13”) round hole in the
back of the case to accommodate communications, I/O, and/or auxiliary power
wiring.
NOTE
For retrofitting S1 style switchboard cases, a pre-drilled backplate is included. To use it, remove the
backplate from the old switchboard case and replace it with the supplied backplate.
2. Place the supplied 29mm (1.13”) nylon bushing into the drilled hole if desired.
Refer to “Unit Dimensions” on page161.
3. Place the switchboard case into the prepared mounting hole. Attach the
mounting screws.
4. Wire the phase voltages and currents to the terminal posts on the rear of the case.
5. Read the warning label on the green captured-wire plug.
6. Connect any communications, I/O, and/or auxiliary power wiring to the meter.
For the P24 power supply option, ensure that the auxiliary power cable is
powered off.
Pass all wiring through the switchboard case using the round hole in back.
Connect the communications and I/O wiring to the meter; for the P24 power
supply option, also connect the auxiliary power cable to the meter’s power
supply terminals.
Slide the meter chassis into position while feeding the excess wiring
through the hole in the rear of the switchboard case, making sure none of
the wires are pinched.
Secure the meter by locking the two chassis levers into position.
Wire any external communications and I/O; for the P24 power supply
option, connect the other end of the auxiliary power cable to an external
dedicated 20 to 60VDC source that is powered down.
7. Connect the ribbon cable to the back of the display on the case cover.
8. Energize the meter as follows:
For the P24 power supply option, power up the auxiliary power
(20 to 60VDC) source.
