DBC1220GL Installation Manual Rev I.docx
Select A Suitable Location
This device is designed for indoor use only. If
installing in an external location, the
DBC1220GL must be housed in a suitable
well-ventilated enclosure. Choose a dry
location that will be accessible after the
installation is complete. The DBC1220GL
should be mounted
vertically, the right way
up.
An air gap of 100mm on each side and at
the top and bottom of the device should be
adhered to. This air gap is required to ensure
the serviceability of the DBC1220GL without
its 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 DBC1220GL has integral mounting
brackets attached to the inside of the
enclosure. The brackets are designed to
accommodate 4 fixing screws up to 8mm
diameter. The DBC1220GL can be fixed to
the wall without opening the cabinet or
removing covers. 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 the internal components.
Allow for Cable Entry
Supply and load cables enter the
enclosure at the top. If these cables are
fed from below the mounting position,
they should be routed around the
enclosure to enter at the top, or
alternative knockouts are provided on the
right side below the lid line. An
alternative method is to stand the
enclosure 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 enclosure
and the mounting surface, and enter the
enclosure via the cutout provided on the
mounting face. The control cables enter
at the bottom of the enclosure. Control
cables should never be run in the mains
