2.4.2 Remarks for Pumps with

EExe II T3-Motors

There are no objections against using the vacuum pump

in an explosion hazard area of ZONE 1, a temperature

class T3 and explosion group IIB provided the following

conditions will be fulfilled:

Caution

Install a suitable motor protection switch in

front of the vacuum pump’s electric motor. If

the vacuum pump is supplied as ready-to-

plug-in unit the customer himself must

install the motor protection switch and in a

pressure-resistant encapsulation version.

If the vacuum function fails the vacuum

pump must be switched off automatically

via an interruption of the power supply.

Due to the measures taken the vacuum

pump is not suited to pump oxygen and

explosive atmosphere.
