22 Controller Installation

8.3 Mounting, space and ventilation requirements

The PSk2 controller must be mounted to a solid wall or
back-plate. Ensure that the mounting back-plate can sup-
port the weight of the controller. The user is responsible for
correct and safe mounting.
First, mark all drill holes. Refer to "Table 4: Controller di-
mensions for installation" on page 21 and use the values
W2, H3 and d. Fit all screws, leave about 10 mm / 0.4" space
between the screw's head and the wall. Hang the controller
on the wall. Finally, tighten all screws.
PSk2 controllers can be mounted side by side.
CAUTION – The controller must be
mounted directly on a vertical, flat wall or
equipped with a back plate. The controller
must not be installed inside an additional
enclosure, box or any other hollow space
that could result in the controller not
being efficiently cooled. Inefficient cooling
will reduce the system performance and
can damage the controller.

350 mm / 14"
CAUTION – To ensure effective cooling, the
controller must be installed vertically with
at least 30 cm / 12" space above and below
the casing.
CAUTION – When installed in an indoor
location sufficient ventilation must be
ensured by a vent or similar ventilation
device. Do not install in a place which is
exposed to direct sunlight.
CAUTION – The heat sink gets hot during
operation. Do not touch it until it has
cooled down to avoid the risk of burns.
CAUTION – Do not let any swarf (drilling
chips) fall into the controller fins or fan
during installation.
