DANGER
Danger due to damaged seals
Damaged seals can result in the failure of the explosion protection.
This can cause faults which can result in eventual or immediate death, serious injury or
material damage.
Only operate the machine with intact, undamaged seals.
4.4 Machines without final paint coating
For machines, which are only delivered with primer, you must paint them to comply with the
applicable guidelines
for the specific application. The primer alone does not provide adequate
corrosion protection.
The paint applied must conform to the requirements to avoid electrostatic charging, see
EN 60079-0.
Note
Please contact the Service Center for recommendations relating to the paint finish.
4.5 Corrosion protection for bare metal surfaces
The lower side of the machine mounting feet or the flange surface is bare metal. Ensure that
there is adequate corrosion protection, e.g. using grease, sealing paste or a similar product.
The terminal box cover also has bare metal surfaces. Here, only use a suitable grease to
guarantee protection against corrosion.
4.6 Ensuring adequate cooling
Ensure that the machine is sufficiently cooled by the cooling air flow at the installation site:
●
Ensure that the cooling air can flow in and out unobstructed. The full air flow provided by
the fan is only possible if air can freely enter the impeller. In the axial direction, ensure a
clearance of at least 1 x air intake diameter.
● Make sure that the machine does not draw in the hot discharged air again.
● For machines with a vertical type construction with an air intake from above, ensure that
the air inlets are protected against the ingress of foreign bodies and water.
