Fujitronic Programmable Operation Display UG520H-x - Manual (Page 4)

CAUTION
[Notes on System Design]
•
Never bundle control cables and input/output cables with high-voltage and large-current
carrying cables such as power supply cables. Keep these cables at least 200 mm away from
the power supply or high-voltage cables. Otherwise, malfunction may occur due to noise.
•
For use in a nuclear energy facility, or other facility of such official importance, please consult
your local distributor.
[Notes on Installation]
•
Operate (or store) POD under the conditions indicated in this manual and related manuals.
Failure to do so could cause fire, malfunction, physical damage or deterioration.
•
Understand the following environmental limits for use and storage of POD. Otherwise, fire or
damage to the unit may result.
-Avoid locations where there is a possibility that water, corrosive gas, flammable gas,
solvents, grinding fluids or cutting oil can come into contact with the unit.
-Avoid high temperature, high humidity, and outside weather conditions, such as wind, rain
or direct sunlight.
-Avoid locations where excessive dust, salt, and metallic particles are present.
-Avoid installing the unit in a location where vibration or physical shock may be transmitted.
•
Equipment must be correctly mounted so that the main terminal of POD will not be touched
inadvertently.
•
Tighten the POD mounting screws to the specified torque. Excessive tightening may distort the
panel surface. Loose tightening may cause POD to come off, malfunction or be short-circuited.
•
Tighten terminal screws on the power input terminal block equally to a torque of 0.5 Nom.
•
Check the appearance of POD when it is unpacked. Do not use the unit if any damage or
deformation is found.
•
POD has a glass screen. Do not drop or give physical shock to the unit.
[Notes on Cable Connection]
•
Connect the cables correctly to the terminals of POD in accordance with the specified voltage
and wattage. Over-voltage, over-wattage or incorrect cable connection could cause fire,
malfunction or damage to the unit.
•
Be sure to establish a ground of POD. The FG terminal must be used exclusively for the unit
with the level of grounding resistance less than 100W.
•
Prevent any conductive particles from entering into POD. Failure to do so may lead to fire,
damage or malfunction.
