Main Board Wiring Specifications
There are several wiring requirements to consider before connecting circuits to the main board: (1) the circuit separation,
and (2) wiring types.
Circuit Separation
Proper separation between the different types of circuits must be maintained between Power Limited, Non-Power Limited, and
High Voltage wiring to reduce electrical interferences, transient voltage or voltage ratings.
y y Separations between the different wiring types must be maintained by at least ¼ inch and the wire insulation must be for the
higher voltage.
y y The control panel cabinet has sufficient knockouts located around the periphery allowing the installer to maintain separation
between power limited and non-power limited connections.
Wiring Types
Wiring specifications must be followed to prevent damage or other consequences.
Refer to table below for a breakout of the different wiring requirements shown by circuit type:
