MAINTENANCE OF EXPLOSION PROTECTION

Maintenance o explosion protection during operation. Electric machines must

be protected against overheating due to overloads. The type o protection
depends on the type o operation as well as the electric machine and its use.
Explosion-proo electric motors are usually certi ed or S1 type o operation, i.
e. continuous operation. Other duties are allowed only i the temperature o the
motor is controlled by reliable devices.

Maintenance o explosion protection/Construction

Explosion-protected electric motors are used in industrial plants with a potentially CONSTRUCTION
explosive atmosphere containing in ammable umes (vapours) or gases (i. e.
chemical industry, oil re neries...) as well as in mines where methane is present.
Explosion protection standards taken into consideration during manu acturing
These are the three-phase, asynchronous electric motors with short-

EN 60079-1, EN 60079-7 (IEC 60079-0, IEC 60079-1) standards. The
enclosures o electric motors are designed to be “ ameproo “ according to Standard IEC EN-CENELEC

Terminal box
The terminal box is tted to the top o the motor with the cable entering rom the an end o the motor. It can be repositioned in steps o 90° to 180° to suit the
application. The motors with direct starting are equipped with 3 connection terminals. 6 connection terminals are tted to Star-Delta, two speed and dual voltage
machines. The electric motors with sizes 71 to 132 inclusive and Ex e terminal boxes have 6 additional connection terminals or PTC sensors, heaters etc. The
motors with Ex d terminal boxes are also equipped with 6 connection terminals. Exception is the 71 motor with only 4 connection terminals. Each terminal box
has one connection terminal or the protective conductor. Ex d terminal boxes include a threaded entry to accept Ex d cable glands (see table below). Ex d thread
reducers or adaptors can be included as an option or other thread sizes and thread orms.
