• DOK-DIAX02-DDC01******-PRJ1-EN-E1,44 • 01.97
Safety Clearances The bleeder resistor in the DDC heats up during operation. Flammable
materials or parts which could deform in the hot air stream, e.g., polyvinylchloride
cable conduits, must maintain a minimum clearance of 300 mm to the air
outlet.
4. Mounting the DDC 1.2
The DDC 1.2 generally needs no maintenance. If it is operated in a
very dirty environment, and if heatsink could become clogged, e.g.,
by foundry dust, then these should be regularly checked. If the device
function is inhibited by dirt, then both the blower and the heatsink
should be cleaned.
