Safety instructions

General safety instructions

These safety instructions are intended for all personnel who work on the drive. For

complete safety instructions, see the drive manuals.

Ignoring these instructions can cause physical injury or death, or damage the

equipment. All electrical installations and maintenance work on the drive should be

carried out by qualified electricians only.

WARNING!

• Make sure that the drive and all adjoining equipment are properly

earthed.

• Do not attempt any maintenance on powered drive.

• After switching off the mains, always allow the intermediate circuit

capacitors 5 minutes to discharge before doing any maintenance

work on frequency converter, the motor or the motor cable.

• It is good practice to check (with a voltage indicating instrument) that

the drive is in fact discharged before beginning work.

WARNING!

If the demo unit is operated within the transportation enclosure, please

note that the motors and drives have less air available for cooling, which

may result in overheating.

Safety input connections

The safety connections in the demo are made as in the picture below. Safety inputs

2, 3 and 4 are not in use by default. Note that if the IO-cable is not connected, it will

automatically result in activation of the STO (safe torque off).
