APPLICATION AND EXPLOSION PROTECTION
The explosion-proof asynchronous three-phase squirrel-cage motors of the type 5KTC are designed for their
application in industrial buildings with highly explosive atmospheres caused by flammable gases, steam or liquids.
Explosion-proof motor versions are:
”Explosion-proof enclosure” for the motor housing and ”Increased safety” for the terminal box according to EN
60079-0: 2009, EN 60079-1: 2007 and 60079-7: 2007. The cover of the terminal box carries the Ex imprint.
”Explosion-proof enclosure” for the motor housing and the terminal box according EN 60079-0: 2009 and EN
60079-1: 2007. The cover of the terminal box carries Ex imprint.
The standard electric motor is suitable for the T4 temperature class.
The exact indication of the explosion protection can be found on nameplate of the motor.
INSTALLATION (MOUNTING) OF THE ELECTRIC MOTOR
THE ELECTRIC MOTOR MUST BE MOUNTED BY QUALIFIED PERSONS IN ORDER TO AVOID POSSIBLE
DAMAGES DURING OPERATION CAUSED BY AN INCORRECT INSTALLATION.
The following rules must be observed during installation:
- strictly adhere to the installation instructions,
- check whether the explosion protection corresponds to the environment or not
(sector, gas group , temperature group),
- check the effects of the environment on the operation of the electric motor (aggressive environment,
temperature, dust ...),
- consider particulars and requirements of room/plant,
- make sure that the correct tools and devices are used,
- observe the motor safety instructions,
- make sure that the means for personal safety are used.
The electric motors are manufactured in such a way as to function in a mildly humid and dusty atmosphere under
temperatures between -50

C to 60

C without requiring additional protection. If ambient temperature is below -
20
0
C then motors must be equiped with space heaters ( Ex d motors only).
If mounted (installed) outdoors, the motors must be protected from direct sunlight. If the motor is mounted and
operated in vertical position, the fan openings must be protected against the ingress of water or any other forein
objects by fixing the cover above them.
Insulation of the electric motors consists of water-resistant materials and high-quality coating. If stored correctly, it
is therefore not necessary to carry out special tests before connecting the motor to the power supply.
When mounting the elements (such as clutch, pulley) on to the motor shaft, please pay particular attention to the
bearings. The axial forces caused by possible impacts during installation must not have any effect on the
bearings.
