• Wireless devices and other equipment that generates electromagnetic waves should never
be installed in the same control panel with the Inverter.
• The DC power supply used for communications should have reinforced or double insulation.
• An Inverter control terminal has only basic insulation. More insulation is required if the termi-
nal is wired to parts people are likely to touch.

• Always connect the Inverter and power supply via a molded case circuit breaker
(MCCB) suitable to the Inverter for protecting the Inverter from damage that may result from short-cir-
cuiting.
• Use one MCCB per Inverter.
• Select a suitable MCCB from the following table.
• With a 400-V-class Inverter, be sure to ground to a neutral point of the power supply.
