Routing line voltage cables through the sides of the
enclosure is not allowed as it will violate NEC re-
quirements separating Class 1 and Class 2 circuits.
2.
Plan where to land the line and load conductors
before routing cables. Write down your plan on the
panel schedule in the plastic pocket on the panel
door.
3.
Power supply should be supplied from a dedicated
breaker. Land 120v or 277v on appropriate lugs
and Neutral and Ground as indicated.

Do not power-up the panel electronics until the bus
has been activated (see the Quick Start Guide).
You can check for faults while landing conductors
on the relays with the following steps:
4.
Land Line and Load conductors on the same termi-
nal lug. Label "line" conductor with the breaker ID.
5.
Check the line. Switch breakers on and clear any
faults. Switch breakers off.
6.
Move the load conductors to the load terminal lug
on each relay once tested.

Torque Spec Instructions
The Torque spec for the relay terminal block is 16in-
lbs.
With a 1" diameter = ½" radius screw driver, this
means a turning force of 32 lbs.

Tighten and Wiggle
Copper is "ductile." That means that it can compress
and fl ow. To ensure a good connection in the terminal
