Before installation:
Read this manual completely and gather all information on the product. Make sure that
you understand it fully. Check that your application does not exceed the safe operating
specifications for this product.
WARNING - SAFETY DURING INSTALLATION
The product must be installed by qualified service personnel
and built in to an apparatus cabinet or similar, where access is
restricted to service personnel only.
During installation, ensure a protective earthing conductor is
first connected to the protective earthing terminal (only valid for
metallic housings). Westermo recommends a cross-sectional area
of at least 4 mm2.
Upon removal of the product, ensure that the protective earthing
conductor is disconnected last.
WARNING - HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur
when connected to a power supply.
WARNING - PROTECTIVE FUSE
The power supply wiring must be sufficiently fused.
It must be possible to disconnect manually from the power supply.
Ensure compliance to national installation regulations.
This product has no internal fuse and should be connected via an
external fuse for protection.
WARNING - REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords
with a cable diameter of AWG 26 or larger. Regarding power
cable dimensions, see Interface Specifications.

66641-22410
CAUTION - HOT SURFACE
Be aware that the surface of this product may become hot.
When it is operated at high temperatures, the external surface
may exceed Touch Temperature Limit according to the product's
relevant electrical safety standard.
CAUTION - ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damages to internal electronic
parts by discharging your body to a grounding point (e.g. use a
wrist strap).

Notice:
This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference in a residential installation.
This equipment generates, uses and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful inter-
ference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one
or more of the following measures:
… Reorient or relocate the receiving antenna
… Increase the separation between the equipment and receiver
… Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected
… Consult the dealer or an experienced radio/TV technician for help.

Connection of cables
Recommended tightening torque for the M12 connectors: 0.6 Nm
Note that unused connectors must be covered by a protective cap (delivered with the
unit), tightened to the specified torque, in order to fulfill the specified ingress protection
code.
Removal
Disconnect all cables and unscrew the unit from the wall.
Time For Replacement < 15 minutes
Cooling
This unit relies on convection cooling. Make sure that it is installed so that the ambient
temperature is within the specified temperature range, e.g. by avoiding obstruction of the
airflow around the unit.
Wall mounting
There are four 6 mm bore holes intended for mounting the unit. The unit can be
mounted vertical or horizontal. Use four M5 screws with 12 mm washer on a flat and
stable surface.
