SIMOVERT MASTERDRIVES units are operated at high voltages.
All work carried out on or with the equipment must conform to all the
national electrical codes (VBG 4 in Germany).
Maintenance and service work may only be executed by qualified
personnel.
Only spare parts authorized by the manufacturer may be used.
The prescribed maintenance intervals and also the instructions for
repair and replacement must be complied with.
Hazardous voltages are still present in the drive units up to 5 minutes
after the converter has been powered down due to the DC link
capacitors. Thus, the unit or the DC link terminals must not be worked
on until at least after this delay time.
The power terminals and control terminals can still be at hazardous
voltage levels even when the motor is stationary.
If it is absolutely necessary that the drive converter be worked on when
powered-up:
♦ Never touch any live parts.
♦ Only use the appropriate measuring and test equipment and
protective clothing.
♦ Always stand on an ungrounded, isolated and ESD-compatible pad.
If these warnings are not observed, this can result in death, severe
bodily injury or significant material damage.
A fan is mounted at the lower section of the inverter for cooling the
power section.
The fan is fed by the 24 V supply voltage and switched on and off by
electronic control according to the heat sink temperature.
The fan is designed for a service life of L
ambient temperature of
T = 45 °C. It must be exchanged in good time to ensure the availability
u
of the unit.
