NOTES
1. DO NOT GROUND THE SHIELD INSIDE THE ELECTRICAL PANEL. All Modbus wires,
including the shield, should be insulated to prevent accidental contact with high
voltage conductors.
2. The Modbus cable should be mechanically secured where it enters the electrical
panel.
3. All Modbus devices should be connected together in a daisy-chain fashion. The
first and last devices in the chain should have a 120Ω terminating resistor between
(+) and (-).
4. The Modbus cable should be shielded twisted pair wire BELDEN 1120A or similar.
WARNING: After wiring, remove all scraps of wire or foil
shield from the electrical panel. This could be DANGER-
OUS if wire scraps come into contact with high voltage
wires!

Note: The Enercept cannot communicate on the network bus without power.
Therefore, it is best to connect the voltage leads ahead of switching devices.
5. For information regarding software setup, see the Modbus protocol specifications
available at www.veris.com/Modbus/.
6. Check power reading (these calculations are approximations only).
Expected power:
kW = Volts x Amps x 1.732 x PF / 1000
kW = Horsepower x 0.746
