Wiring of Master Module

Terminal Blocks Wire Sizes and Screw Torques
Observe all wire lug sizes and screw torques. Refer to
Appendix C, Specifications.

Chassis Grounding

Electrically bond the Master

Module to the wiring installation via a bonding
terminal. Refer to Technical Specifications,
Appendix C. This protective earthing terminal shall
have no other function per local codes (ground bond

largest measured conductor size). All ground wires

should be kept as short as possible; 30cm (12 in.) or
less is suggested.

Control Power

The power required by the Master Module is less
than 25VA to facilitate retrofit applications, but the
terminal block connections accept up to #12 AWG

(4 mm

2

) wire with lugs. The Master Module can be

powered directly from a local branch circuit. It
should be fused per local code.

Voltage and Current Inputs

Voltage Input and Potential Transformer (PT) Selection

All Bulletin 1403-xM Powermonitor II devices
handle direct connection for line to neutral voltages
of 120, 277, and 347 (line to line voltages of 208,
480, and 600V, respectively).

!

ATTENTION: Failure to comply
with these mounting requirements
may cause damage to the Display
Module or compromise the IP65
[NEMA/UL 508, Type 4X (Indoor)]
degree of protection per International
Standard IEC 529.
