other applications, otherwise fire may result.
The drive cannot be used by itself for elevators,
life-preservation equipment or other equipment
which is directly related to human safety. In such
situations, sufficient consideration should be
given to overall system configuration, not just to
the drive, otherwise serious accidents could
result.

wise electric shocks or fires may result.
Wiring work should only be carried out by suit-
ably qualified personnel, otherwise electric
shocks may result.
Make absolutely sure that the power supply is
turned off (open) before wiring, otherwise electric
shocks may result.
Wiring work should only be carried out after the
