Observe the safety precautions (see Chapter 3).
6.1. Installation
Before installation, store the motor at the installation location
for 3 hours to bring it up to room temperature.
Danger of explosion from insufficient cooling
Install the motor so that the motor fan can intake
sufficient cooling air.
WARNING
Ensure sufficient ventilation and heat dissipation
around the motor.
Make sure that the installation location is dry and the motor is
protected against rain, splash, hose and drip water.
Protect the motor from dust.
Protect the motor from vibrations and jolts.
6.2. Electrical connection
Extreme danger from electrical shock!

is certain that it can be safely operated in the potentially explo-
sive atmosphere that is present.
The general safety and commissioning notes apply to the
electrical wiring.

ried out by a person qualified to do so, who is authorized to
connect electrical equipment in hazardous environments.
Area A per DI EN 60034-1 (voltage ± 5%, frequency ± 2%)
must be maintained so that the temperature is kept within the
permissible limits. Exceptions are permitted only if they are in-
dicated on the motor output plate.
Only electrical equipment that is absolutely necessary for
operating the motor should be located in the hazardous area.
The installation, or additional measures, must protect the motor
