Installation and connection

 Only install and operate the motor under the operating pa-
rameters and conditions described in Chapter 4, Technical da-
ta, and Section 2.3, Use in hazardous areas.
 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!
 Only have the motor connected by an authorized
specialist.
DANGER
 Only have the motor connected when the power
supply is disconnected.
 The customary national and international regulations on the
set-up of electrical systems in potentially explosive atmos-
pheres must be observed.
 The motor may only be connected to the electrical supply, if it
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.
 Connection of the motor to the electrical supply must be car-
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
against water as well as against electrical, chemical, thermal,
