6. Installation and connection
Î 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.
Î Observe the safety precautions (see Chapter 3).
6.1. Installation
Î Before installation, store the motor at the installation location
for 3 hours to bring it up to room temperature.
WARNING
Danger of explosion from insufficient cooling
Î Install the motor so that the motor fan can intake
sufficient cooling air.
Î Ensure sufficient ventilation and heat dissipation
around the motor.
Î Make sure that the installation location is dry and the motor is
protected against rain, splash, hose and drip water.
Î Protect the motor from dust.
Î Protect the motor from vibrations and jolts.
6.2. Electrical connection
DANGER
Extreme danger from electrical shock!
Î Only have the motor connected by an authorized
specialist.
Î Only have the motor connected when the power
supply is disconnected.
Î The customary national and international regulations on the
set-up of electrical systems in potentially explosive atmos-
pheres must be observed.
Î 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.
Î The general safety and commissioning notes apply to the
electrical wiring.
Î 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.
Î Area A per IEC 34-1 (voltage ± 5%, frequency ± 2%) must be
maintained so that the temperature is kept within the permissi-
ble limits. Exceptions are permitted only if they are indicated on
the motor output plate.
Î Only electrical equipment that is absolutely necessary for
operating the motor should be located in the hazardous area.
Î The installation, or additional measures, must protect the motor
