Select a suitable location
This device is designed for indoor use only. If
installing in an external location, the device
must be housed in a suitable well-ventilated
enclosure. Choose a dry location, that will be
accessible after the installation is complete.
To ensure the cooling system functions
correctly, the device should only be mounted
vertically, the right way up. The device will
generate heat when operating, approximately
2 Watts per Amp of load, and requires an air
gap of 200mm on each side and at the top and
bottom of the device. This air gap is also
required to ensure serviceability of the device
without complete removal from the mounting
surface. This device may emit some
mechanical noise. Take this into account
when deciding the mounting location.
Fixing the Device
The device has integral mounting brackets
attached to the enclosure. The brackets are
designed to accommodate fixing screws up to
8mm diameter. The device can be fixed to the
wall without opening the cabinet or removing
the cover. Make sure no dust or other debris
enters the device during installation. Do not
leave the front cover off for any length of time.
Excessive dust and dirt can degrade the
cooling of internal components.
Allow For Cable Entry
Supply and Load cables should enter the
device at the top. If these cables are fed from
below the mounting position, they should be
routed around the device to enter at the top.
An alternative method is to stand the device off
from the mounting surface by mounting it on a
cable tray or a ‘Unistrut’ style product. The
cables can then be routed between the device
and the mounting surface, and enter the
device via the cutout provided on the mounting
face. The control cables enter at the bottom of
the device. Control cables should never be
run in the mains voltage sections of the device.
