2.8 ATEX Zone 22 for SK 1x5E
(in preparation)
General information
The SK 1x5E can be used in explosion hazard areas with a suitable modification. For this it is important that
all the safety information in the operating instructions is strictly complied with for the prevention of personal
injury and material damage. This is essential to prevent injury and damage.
Qualified personnel
Qualified personnel must be used to carry out work involving the transport, assembly, installation,
commissioning and maintenance. Qualified personnel are persons who due to their training, experience and
instruction, and their knowledge of the relevant standards, accident prevention regulations and operating
conditions are authorised to carry out the necessary activities for commissioning the motor starter. This also
includes knowledge of first aid measures and the local emergency services.
ATTENTION
All work must only be carried out with the power to the system switched off.
If the motor starter is connected to a motor and a gear unit, the EX labelling of the motor and
the gear unit must also be observed.
Safety information
The increased danger in areas with inflammable dust demands the strict observation of the general safety
and commissioning information. The drive unit must comply with the specifications in Planning Guideline
No. 6052101. Explosive concentrations of dust may cause explosions if ignited by hot or sparking objects.
Such explosions may cause serious or fatal injuries to persons or severe material damage.
It is essential that the person responsible for the use of motors and motor starters in explosion hazard areas
is trained in their correct use.
ATTENTION
Before opening the device for the connection of electric cables or other work, the mains
voltage must always be switched off and secured against switching on again !
Temperatures may occur within the motor starter and the motor, which are higher than the
maximum permissible surface temperature of the housing. The device may therefore not be
opened or removed from the motor in an atmosphere of explosive dust!
Impermissibly heavy dust deposits must not be permitted, as these impair the cooling of the
motor starter!
All cable glands which are not used, must be closed with blind screw plugs which are
approved for explosion hazard areas.
Only the original seals may be used.
The protective film covering the diagnostic LEDs in TU4 modules must not be damaged.
Repairs may only be carried out by Getriebebau NORD.
