Preparation for wiring
Determination of wire and fuse sizes
The maximum motor current in your application determines the
recommended wire size. The following table gives the wire size in
AWG. The “Power Lines” column applies to the inverter input
power, output wires to the motor, the earth ground connection,
and any other component. The “Signal Lines” column applies to
any wire connecting to the two green 7 and 8-position connectors
just inside the front enclosure panel.
Danger!
“Use 60/75 °C Cu wire only” or equivalent.
Danger!
“Open Type Equipment”.
Danger!
“A Class 2 circuit wired with Class 1 wire” or equivalent.
Danger!
“Suitable for use on a circuit capable of delivering not
more than 5000 r.m.s. symmetrical amperes, 240 V
maximum”. For models DF51-322.

Field wiring must be made by a UL-listed and CSA-
certified closed-loop terminal connector sized for the wire
gauge involved. Connector must be fixed by using the
crimping tool specified by the connector manufacturer.
h
Be sure to consider the capacity of the circuit-breaker
to be used.
h
Be sure to use larger wires for the power lines if the
distance exceeds 20 meters.
