INSTALLATION AND WIRING
MOUNTING THE CONTROLLER
The outline and mounting hole dimensions are shown for the 1204M and 1205M
controllers in Figure 2, and for the 1209M and 1221M controllers in Figure 3.
The controllers meet the IP54 requirements for environmental protection against
dust and water. Nevertheless, in order to prevent external corrosion and leakage
paths from developing, the mounting location should be carefully chosen to
keep the controller as clean and dry as possible.
It is recommended that the controller be fastened to a clean, flat metal
surface with four M6 bolts, using the holes provided. The mounting surface is
an integral part of the overall heatsinking of the controller, and affects its ability
to dissipate heat. Although not usually necessary, a thermal joint compound
can be used to improve heat conduction from the controller heatsink to the
mounting surface.
