6.0 METER INSTALLATION
6.1 Mounting the Class 3400 Meter
Use appropriately sized mounting hardware to fasten the meter enclosure to the
selected mounting surface. The four housing mounting holes are centered 8.75” H x 4”
W for the CL3400.
NOTE: Units housed in UL Type 1 enclosures must only be installed in indoor envi-
ronments, where they will not be affected by the elements.
6.2 Main Power Board Connections
1. Installing a temporary ground for ESD protection:
With all circuits de-energized, connect a temporary protective earth ground con-
nection for ESD protection. Prior to performing any unit wiring, be sure to dis-
charge any static on your person.
2. Installing the Class 3400 protective earth ground:
Connect an earth ground wire to the Class 3400 protective earth ground lug with
a torque of 7 N-m.
WARNING
Failure to attach the protective earth ground wire securely to the meter creates
a potential shock hazard. Do not operate the meter without a protective earth
ground connection securely installed.
3. Wire Entry:
CL3400 meters are supplied with two 3/4” conduit K.O.s on the bottom of the 4X
enclosure for all wiring. The Type1 enclosures are supplied with three 3/4” con-
duit K.O.s.
Route the appropriate cabling to and through the respective enclosure opening.
After installing the conduit fitting and conduit, verify that each conduit slip nut is
securely tightened to its respective conduit fitting. Any unused openings must be
sealed with a UL rated plugging device suitable for the rating of the enclosure.
4. Unit MAINS Wiring:
The first four positions of terminal block TB1, located at the bottom left corner of
the main power board, are clearly labeled Phase A, B, C, N (neutral). Earth
Ground MUST be connected to the PCB mounting screw in the lower right cor-
ner.
Connect the NEUTRAL wire to the appropriate terminal block position.
