WARNING:
FIRE AND PERSONAL INJURY HAZARD
This drive is designed for variable-speed opera-
tion of three-phase induction motors. It cannot
be used with single-phase motors or for any
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.

as a metal surface, otherwise fires may result.
Do not place the drive near flammable materials,
otherwise fires may result.

porting. The drive could be damaged and cause
injury to personnel.
Do not let any scraps of thread, paper, sawdust,
dirt, metal shavings or other foreign objects get
inside the drive or onto the cooling fins, other-
wise fire or problems with operation may result.
Do not install and operate the drive if it is dam-
aged or if some of the parts are missing. Doing
so may result in severe personal injury.
Do not touch the drive cooling fin because the
cooling fin reaches high temperatures during
operation, otherwise personal injury may result.

WIRING

WARNING:

FIRE AND ELECTRIC SHOCK HAZARD.

When connecting the drive to a power supply, be
sure to connect it via a circuit breaker, a leakage
current breaker or a fuse, otherwise fires may
result.
AC input fuses are required to validate the UL
listing of this device.
Use only fuses and circuit breakers with rated
capacities that are suitable for use with the drive.
Failure to do so may result in fire.
Connect the drive with a secure ground, other-
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
drive has been installed, otherwise electric
shocks or injury may result.
