Ignition hazard
Protective measures to be observed by the customer
Ignition hazard with bought-in motor components
Refer to the documentation for the motor.
Comply with the monitoring intervals.
The insulation resistance needs to be greater then 5
MOhm.
Provide a time-delay residual current device.
Provide overload protection by means of a motor protec‐
tion switch or an equivalent protective device.
Observe the minimum spacing between the air inlet on the
fan hood and any obstacles.
Avoid deposits of dust more then 5 mm deep.
Connect the earth wire.
Max. installation height: 1,000 m.a.s.l.
Ignition hazard with bought-in actuator or control drive
components
Refer to the documentation for the actuator.
Wait 3 minutes after switching off before opening the
housing.
Ignition hazard caused by bought-in proximity switch
NJ1.5-8GM-N (stroke sensor)
Refer to the documentation for the proximity switch (elec‐
trical installation, maintenance, ...).
WARNING!
ATEX pumps in areas at risk from explosion
–
The operator must observe the Operator Directive
when operating equipment in areas at risk of explo‐
sion.
–
Only clean plastic parts carefully with a damp cloth
to avoid electrostatic charges and sparks.
WARNING!
Motor may overheat
If the necessary cooling air supply is not guaranteed, the
motor may overheat. In an area at risk from explosion, it
could trigger an explosion.
–
Maintain sufficient clearance between the air intake
opening and the walls. The distance should be
greater than 1/4 of the diameter of the air intake
opening.
–
The fan must not suck in the exhaust air from other
devices.
WARNING!
ATEX pumps in areas at risk from explosion
–
Metering pumps must have an appropriate safety
relief valve on the discharge side (to protect against
excessive heating due to overloading or impact
sparks caused by the breakage of power end parts).
