HONEYWELL E-MON® MMU-STYLE METERS
6.3 RS485 Communication Wiring
The RS485 Communication wiring is installed by connecting the leads to the
appropriate terminals on the 3-position RS485 terminal strip mounted on the
back panel of the enclosure. The wiring terminals are labeled GND, HIGH, and
LOW to correspond to the appropriate connections of the communication
cabling. Tighten the terminals to 9 in-lbs of torque. Class 1 rated, Belden 1120A
cable (600V) is to be used for communication wiring in MMU enclosures. The
communication cabling must be routed away from the mains wiring.
