3.4 Main Circuit Terminal Block Wiring
DANGER! Electrical Shock Hazard. 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 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.
•
Put the wire all the way into the terminal block. Remove the insulation from the wire to the recommended wire
stripping length to fit the wire with insulation in the plastic housing.
• Use a torque driver, torque ratchet, or torque wrench for the screws. A slotted driver or a hex tool will be
necessary to wire the screw clamp terminal. Use applicable tools as specified by the recommended conditions in
the product manual.
• If you use power tools to tighten the terminal screws, use a low speed setting (300 to 400 r/min). Failure to obey
can cause damage to the terminal screws.
•
Wire gauges on existing drive models to be replaced may not match wire gauge ranges on new drives.
•
Do not tighten the terminal screws at an angle of 5 degrees or more. Failure to obey can cause damage to the
terminal screws.
Figure 3.19 Permitted Angle
• Put the bit all the way into the hex socket to tighten the hex socket cap screw.
• When tightening slotted screws, hold the straight-edge screwdriver perpendicularly to the screw. Do not allow
the tip of the screwdriver to shift or protrude from the groove of the screw.
