Installation
Disconnect and lock out all power sources during installation and configuration.
If making connections to the meter through more than one metallic conduit, use a bonding
plate (Veris part number AH11 or equivalent) to prevent electric shock.
1. Verify that the serial number on the meter matches the serial numbers on the current transformers (CTs). These are calibrated
as a set, and mixing transformers with non-matching meters may damage the device when power is applied. The meter’s serial
number is printed on the label affixed to the inside of the front cover, and the CT serial number is on the CT label. If using 100 A
CTs, serial number matching does not apply.
Match serial numbers
between meters and CTs.
Serial number matching does
not apply if using 100 A CTs.
2. Mount the meter.
3. Attach the CTs to the conductors. Local code requirements may require a mounting bracket. For maximum accuracy, run the
conductor through the center of the current transformer window.
4. Optional step, per NEC and local regulations:
Attach external fuses (not included with the H81xx devices). Verify that the fuse
rating is adequate for the applied voltage, with a current rating of ½ Amp (T) slow blow. Select fuses with a fault current rating
that matches the power source rating.
