[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) GV 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 GV. 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 GV will not be touched
inadvertently.
•Tighten the GV mounting screws to the specified torque. Excessive tightening may distort the
panel surface. Loose tightening may cause GV to come off, malfunction or be short-circuited.
•Tighten terminal screws on the power input terminal block equally to a torque of 0.5 N•m.
•Check the appearance of GV when it is unpacked. Do not use the unit if any damage or
deformation is found.
•GV 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 GV 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 GV. The FG terminal must be used exclusively for the unit with
the level of grounding resistance less than 100Ω.
•Prevent any conductive particles from entering into GV. Failure to do so may lead to fire,
damage or malfunction.
