Connecting-up

SIMOVERT MASTER DRIVES are operated at high voltages.
The equipment must be in a no-voltage condition (disconnected from the supply) before any
work is carried-out!
Only professionally trained, qualified personnel must work on or with the unit.
Death, severe bodily injury or significant material damage could occur if these warning
instructions are not observed.
Extreme caution should be taken when working-on the unit when it is open, as external
power supplies may be connected. The power terminals and control terminals can still be at
hazardous potentials even when the motor is stationary.
Hazardous voltages are still present in the unit up to 5 minutes after it has been powered-
down due to the DC link capacitors. Thus, the appropriate delay time must be observed
before opening-up the unit.
Forming the DC link capacitors:
The storage time should not exceed one year. The converter DC link capacitors must be
formed at start-up if the unit has been stored for a longer period of time.
Forming is described in the Instruction Manual, Part 2.
When the DC link is supplied from a central unit, it must be ensured that the converter is
reliably isolated from the DC link voltage!
The user is responsible, that the motor, converter and any other associated devices or units
are installed and connected-up according to all of the recognized regulations in that
particular country as well as other regionally valid regulations. Cable dimensioning, fusing,
grounding, shutdown, isolation and overcurrent protection should be especially observed.
♦ Cabling/wiring: Connecting cables should be dimensioned according to the local regulations and according
to section „Power connections". The insulation should be suitable for 75°C.
