*13
Do not ground the control circuit terminals AC or connect them to the drive chassis.
NOTICE
Do not ground the AC control circuit terminals and only connect the AC
terminals according to the product instructions. If you connect the AC terminals incorrectly, it can
cause damage to the drive.
*14
Connect the positive lead from an external 24 Vdc power supply to terminal PS and the negative lead to
terminal AC.
NOTICE
Connect terminals PS and AC correctly for the 24 V power supply. If you
connect the wires to the incorrect terminals, it will cause damage to the drive.
*15
Set DIP switch S2 to
“
ON
”
to enable the termination resistor in the last drive in a MEMOBUS/Modbus
network.
*16
Use only Sourcing Mode for Safe Disable input.
*17
Use multi-function analog monitor outputs with analog frequency meters, ammeters, voltmeters, and
wattmeters. Do not use monitor outputs with feedback-type signal devices.
*18
Jumper S5 sets terminal AM for voltage or current output. The default setting for S5 is voltage output (

side).
*19
Disconnect the wire jumpers between H1 and HC and H2 and HC to use the Safe Disable input.

Main Circuit Terminal Block Wiring Procedure
DANGER
Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an
energized drive. Before servicing, disconnect all power to the equipment and wait for the time specified on
the warning label at a minimum. The internal capacitor stays charged after the drive is de-energized. The
charge indicator LED extinguishes when the DC bus voltage decreases below 50 Vdc. When all indicators
are OFF, measure for dangerous voltages to make sure that the drive is safe. If you do work on the drive
when it is energized, it will cause serious injury or death from electrical shock.

Wire to the Main Circuit Terminal Block
Wire to the main circuit terminal block correctly as specified by the instructions in the
manual.
Read these instructions before wiring the terminal block.
Notes on Wiring the Main Circuit Terminal Block
Read these notes before you wire the main circuit terminal block.
•
Use UL-Listed, vinyl-coated insulated copper wires for operation with a continuous
maximum permitted temperature of 75 °C at 600 V.
•
Remove all unwanted objects that are near the terminal block connections.
•
Remove the insulation from the connection wires to the wire stripping lengths shown in
the manual.
•
Do not use bent or crushed wires. Remove the damaged end of the wire before you use
it. Incorrect connections can cause death or serious injury from fire.
•
Do not solder stranded wire. Soldered wire connections can become loose over time
and cause unsatisfactory drive performance.
•
If you use stranded wire, make sure that all of the wire strands are in the connection.
Also, do not twist the stranded wire too much. Incorrect connections can cause death or
serious injury from fire.
