DLE220-S Instruction Manual Rev F.doc
Select a Suitable Location
This device is designed for indoor use only. If
installing in an external location, the DLE220-
S must be housed in a suitable well-ventilated
enclosure. Choose a dry location, that will be
accessible after the installation is complete.
The DLE220-S should be mounted
vertically,
the right way up
. The DLE220-S requires an
air gap of 100mm on each side and at the top
and bottom of the device. This air gap is
required to ensure serviceability of the
DLE220-S 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 DLE220-S has four mounting brackets
that attach to the rear of the enclosure. The
brackets are designed to accommodate 4
fixing screws up to 8mm diameter. The
DLE220-S 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 internal components.
Allow for Cable Entry
Supply, load and load control 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. 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 cut-out provided on the mounting face.
The control cables enter at the bottom of the
enclosure. Control cables should never be
run in the mains voltage sections of the
enclosure.
