Caution: Do not use power factor correction capacitors on the input power lines to the inverter or damage to the control may result.
All external control wiring to the inverter should be run in a separate conduit from all other wiring. The use of shielded twisted pair wire is recommended for all control wiring. The shield of the control wiring should be connected to control terminal CM of the inverter only. The other end of the shield should be taped to the wire jacket to prevent electrical shorts.
Conduit openings are provided at the bottom of the inverter housing to allow power and control wiring entrance to the control. Please refer to the inverter outline drawings located in Section 5 of this manual for sizes of the conduit openings.
The following tables show recommended wire size and protection devices along with recommended terminal tightening torques.
