Installation Chapter 2
Back Panel
Use the four brackets on the GuardPLC 1200 controller to mount it
onto a back panel.
If the mounting brackets are not flat before the nuts are tightened, use
additional washers as shims, so the controller does not bend when
you tighten the nuts.

IMPORTANT
For effective cooling:
•
mount the device horizontally.
•
provide a gap of at least 100 mm (3.94 in.) above and below the device and at
least 20 mm (0.79 in.) horizontally between devices.
•
the wire duct can run in the 100 mm (3.94 in.) of free space above and below
the controller if it is no deeper than 40 mm (1.58 in.). If the depth is greater
than 40 mm (1.58 in.), the devices must be placed on stand-offs that match the
depth of the duct. If stand-offs are not used, you must provide a gap of at least
80 mm (3.15 in.) between the device and the duct.
•
select a location where air flows freely or use an additional fan.
•
do not mount the controller or I/O module over a heating device.
•
do not block the ventilation slots on the side of the device.
