Mounting and Assembly
3.1.
Mounting the drive
Directly to the forward
feed unit
A DDC 1 drive has a protection category of IP 65 and can be directly moun-
ted to the forward feed unit.
Cooling
The units must be mounted in such a way that the flow of the cooling air is
not prevented from either entering or exiting the machine.
Safety distances
The bleeder resistor in the DDC heats up during operations. Any flammable
materials or parts that could be affected by this hot air stream (e.g., PVC
cable ducts) should maintain a minimum distance of 300 mm to the air out-
let.

The DDC 1.1 generally requires no maintenace. If it is operated in a
highly polluted environment and the blower mesh and heatsinks are
at risk of becoming excessively dirty (e.g., with foundry dust), then
regular controls are recommended. If the operation of either the
blower or the heatsink are already affected by severe dirt, then
these must be cleaned.
