Levelling the Controller
Note: The mounting surface for the equipment is to be flat within
±1 mm per meter. Installation of metal shims is an acceptable
method of compensating for mounting surfaces that are out of
tolerance. Mounting surfaces that are not flat may inhibit
proper set-up and operation of latches and interlocks of the
equipment.
1. Do not remove the controller from the shipping skid until it is at
the installation area.
2. The controller is bolted to the shipping skids at the front and back
of the cabinet. At the rear, lag bolts hold angle brackets to the
mounting channel at the base of the cabinet. The front lag bolts
are located just inside the lower cabinet door at the corners of the
cabinet bottom. Remove the lag bolts and the angle brackets,
then remove the controller from the shipping skid.
3. It is important to position the controller on a level surface at the
final destination, especially if it will be joined to another one. A
flush mating surface between the controllers is required to ensure
a proper attachment. A level concrete surface should be prepared
for the controller; however, shimming the controller is suitable,
provided the shimming object is dense enough to bear the weight
of the controller for an extended period of time. Sheet metal
shims are suggested (wooden shims are not recommended).
A T T E N T I O N A T T E N T I O N Refer to the technical drawings and installation
manual for your controller’s mounting instructions.
Failure to correctly anchor the cabinet may result
in damage to the equipment or injury to personnel.
