Environmental Considerations
• The UNIPLAY are to be used indoors as built
in displays. Make sure that the display are
installed correctly and that the operating limits
are followed.
• Do not operate the unit in areas subject to
explosion hazards due to flammable gases,
vapours or dusts.
• The unit should not be installed where large
temperature variations and/or high humidity
is present. This will cause condensation in the
device.
• Do not install UNIPLAY in environments where
have inflammable gases.
MOUNTING
Care should be taken when locating equipment
behind the unit to ensure that a.c. power
wiring, PLC output modules, contactors, starters
and relays, and any other source of electrical
interference are located away from the back of
the unit. Particular note should be taken to the
position of variable speed drives and switching
power supplies. Their input and load cables
should be screened to a central star earth point.
Making a NEMA-4 Mounting Panel Details
The unit can be mounted into panels with a depth
of 105mm. It is recommended that the unit be
mounted on the front panel of a steel enclosure,
through an appropriate opening.
Allow a clearance of 25mm around the sides of
the unit for mounting hardware. Allow clearance
for cable connections to the back of the unit.
Unit depth may vary according to cable type
used. Typically, plan a depth to accommodate at
least 105mm behind the panel.
This device should be mounted in the vertical
position on a flat surface of the enclosure.
NEMA-4 Mounting
Put the unit through the panel cut out (See
drawings at the back of this guide). Slide the
clamps (packed with product) into the 4 holes
provided around the case. Tighten the clamping
screws in an even pattern until the unit is secured
in the panel. Screw torque: 0.29 - 0.39 Nm. This
ensures a waterproof seal and prevents the panel
from being deformed.
VESA Mounting
There are 4 holes on back panel for attaching a
VESA mount. 4 x M4 screws of length shorter then
8.0mm required. Screw torque: 0.29 Nm.

DO NOT OVER TIGHTEN MOUNTING CLAMPS!
To seal to NEMA-4 specifications, all
supplied mounting clamps must be
used and panel cannot flex more than
0.253mm.
POWER CONNECTIONS
Make sure that all local and national electrical
standards are met when installing the unit.
Contact your local authorities to determine which
codes apply.
Power Requirements
The UNIPLAY is powered by d.c. power only. The
specified voltage range is 24±20% Volts d.c. This
insures compatibility with most controller d.c.
systems.
