1.3.3.2 Maintenance   
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. Failure to comply could 
cause electrical shocks to personnel. Besides, do not touch the heatsink which can be very hot 
during operation. Replace the cooling fan only when the heatsink has cooled down after 
shutting off the power. In addition, when a synchronous motor is coasting to stop, it 
regenerates voltage to keep the drive terminals live even when the drive power is off. Wait 
until the motor is fully stopped before drive maintenance. Failure to comply could cause 
electrical shocks to personnel.   
1.3.3.3 Wiring Tools 
Use only the tools suggested by the terminal supplier during drive maintenance.   
1.3.3.4 Transportation and installation 
Do not explore the drive to the environment containing the halogens or DOP gas during 
transportation or installation.
