INSTALLATION GUIDE
INSTALLATION
Disconnect power prior to installation.
Any covers that may be displaced during the installation
must be reinstalled before powering the unit.
Mount the meter in an appropriate electrical enclosure
near equipment to be monitored.
Do not install on the load side of a Variable Frequency Drive
(VFD), aka Variable Speed Drive (VSD) or Adjustable Frequency
Drive (AFD).
Observe correct CT orientation.
The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-
mounted to the interior surface of the enclosure.
A. DIN Rail Mounting
1. Attach mounting clips to the underside of the housing by sliding them into the
slots from the inside. The stopping pegs must face the housing, and the outside
edge of the clip must be flush with the outside edge of the housing.
2. Snap the clips onto the DIN rail. See diagram of the underside of the housing
(below).

3. To prevent horizontal shifting across the DIN rail, use two Veris AV02 end stop clips.
B. Screw Mounting
1. Attach the mounting clips to the underside of the housing by sliding them into the
slots from the outside. The stopping pegs must face the housing, and the screw
hole must be exposed on the outside of the housing.
2. Use three #8 screws (not supplied) to mount the meter to the inside of the
enclosure. See diagram of the underside of the housing (below).
