Pre-Operation Checks
Wait for 5 minutes after disconnecting power before working on any part of the system or removing the
Initial checks before applying power:
Check for damage to equipment.
Mains power supply voltage is correct.
Motor is of correct voltage rating and is connected in either star or delta, as appropriate.
Check all external wiring circuits - power, control, motor and earth connections.
Completely disconnect the drive before point to point checking with a buzzer, or when checking
Note:
insulation with a Meggar.
Check for loose ends, clippings, drilling swarf etc. lodged in the drive and system.
If possible check that the motor can be turned freely, and that any cooling fans are intact and free from obstruction.
Ensure the safety of the complete system before the drive is energised:
Ensure that rotation of the motor in either direction will not cause damage.
Ensure that nobody else is working on another part of the system which will be affected by powering up.
Ensure that other equipment will not be adversely affected by powering up.
Prepare to energise the drive and system as follows:
Remove the supply fuses, or isolate using the supply circuit breaker.
Disconnect the load from the motor shaft, if possible.
If any of the drives control terminals are not being used, check whether these unused terminals need to be tied high
or low.
If the motor thermistor terminals are not connected to a motor thermistor, connect these terminals together.
Check external run contacts are open. Check external speed setpoints are all zero.

The drive can be started in either Remote Control or Local Control. By default, the drive will
start in Local Control.
These routines assume that the drive's control terminals are wired as shown in the Control
Wiring Connections in Chapter 3.
