4.1 Wiring Safety

Danger
 Turn off all the power to the equipment before wiring. Wiring during power on could cause
electrical shocks to personnel.
 Allow only qualified personnel for installation, wiring, repairing and parts replacement.
 Capacitors in the drive may still be charged for a short time after shutting off the power.
Wait for the amount of time specified on the drive before any maintenance.
Never touch input or output power cables. Do not connect any circuit to drive enclosure.

Warning
 Properly connect the motor ground terminal. Contacts between the motor ground
terminal and motor enclosure could cause electrical shocks or a fire.
 Ensure terminal screws are all tightened. Loose connection to the main circuit could cause
overheat or a fire.
 Verify if the rated voltage of the drive matches the voltage of the incoming power supply
before applying power.
 Perform all wiring as specified in the wiring diagrams provided when installing braking
unit. Failure to comply could result in drive, braking unit or resistor damage on fire.
 Do not disconnect the motor from the drive while the drive is outputting voltage.
 Do not use unshielded cable for control circuit wiring. Failure to comply could cause
abnormal operation of drive.
 Use shielded twisted-pair cables and connect the shield to ground terminal of the drive.
 Do not modify the drive circuits. Failure to comply could cause drive damage.
 Ensure all connections are correct after connecting the drive with other devices.
 Integral solid state short circuit protection does not provide branch circuit protection.
Branch circuit protection must be provided in accordance with the National Electrical Code
and any additional local codes", or the equivalent
 Overtemperature protection is not provided by the drive.
