(Note 5) Grounding (e.g., mesh grounding) other than Class D grounding can be applied to the
system under a condition which achieves the equivalent effect as with Class D grounding.
For grounding other than Class D, the user shall check for the effect of the grounding.
Note
Avoid installing the Unified Controller nv Series type1 light in places like below.
• A place where the ambient temperature exceeds the range of 0 to 55°C (when the controller is
housed inside the panel, the ambient temperature means the temperature inside the panel)
• A place where the relative humidity exceeds the range of 10 to 95%
• A place with condensations due to a sudden temperature change
• A place where impermissible vibration is applied
• A place where impermissible shock is applied
• A place where corrosive or flammable gas exists (e.g., SO
• A place with lots of dust, salt, or iron powder
• A place exposed to direct sunlight
Observe the following precautions when installing the panel in which the controller unit is housed.
• Install it away from the high-voltage and power panels as far as possible.
• If there is high-frequency equipment or facility, ensure to ground the panel.
• When sharing the channel base with other panels, check for leakage currents from the other
panels or equipment.
