3 Electrical Installation
• Do not loop the ground wire when using more than one drive.
Control Circuit Wiring Precautions

Consider the following precautions for wiring the control circuits.
• Separate control circuit wiring from main circuit wiring and other high-power lines.
• Separate wiring for control circuit terminals MA, MB, MC (contact output) from wiring
to other control circuit terminals.
• For external control power supply use a UL Listed Class 2 power supply.
• Use twisted-pair or shielded twisted-pair cables for control circuits to prevent operating
faults.
• Ground the cable shields with the maximum contact area of the shield and ground.
• Cable shields should be grounded on both cable ends.

Control Circuit Terminals

The figure below shows the control circuit terminal arrangement.
There are two DIP switches, S1 and S3, located on the control board.
SW1
Switches analog input A1 between voltage and current input.
Used to select sourcing (PNP)/sinking (NPN, default) mode for the digital inputs (PNP requires
SW3
external 24 Vdc power supply).

Connects line power to the drive.
Drives with single-phase 200 V input power use terminals R/L1
and S/L2 only (T/L3 is not used).
Connects to the motor.
For connecting a braking resistor.
Linked at shipment. Remove the link to install a DC choke.
For 200 V class: Ground with 100  or less
For 400 V class: Ground with 10  or less
