HARDWARE INSTALLATION
HARDWARE INSTALLATION
CONTROLLER
The controller can be oriented in any position, but
the location should be
carefully chosen to keep the controller as clean and dry as possible. If a clean,
dry mounting location cannot be found, a cover must be used to deflect dirt
and water splash.
1209B, 1221B, and 1221C
The controller should be fastened with four screws to a clean,
fl
at metal surface
that provides an adequate heat sink. The mounting surface is an integral part of
the overall heatsinking of the controller, and affects its ability to dissipate heat.
The case outline and mounting dimensions are shown in Figure 2.
