Use 75 C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.
Precautions for CE Markings
• Only basic insulation to meet the requirements of protection class I and over voltage category II is
provided with control circuit terminals.
Additional insulation may be necessary in the end product to conform to CE requirements.
• For 400 V class Inverters, make sure to ground the supply neutral to conform to CE requirements.
• For conformance to EMC directives, refer to section 3 in this document. For details, refer to the
following document: Document No. EZZ008390 for English version
Receiving
• Do not install or operate any Inverter that is damaged or has missing parts.
Failure to observe this caution may result in injury or equipment damage.
Mounting
• Lift the Inverter by the heatsink. When moving the Inverter, never lift it by the plastic case
or the terminal covers.
Otherwise, the main unit may fall and be damaged.
• Mount the Inverter on nonflammable material (i.e., metal).
Failure to observe this caution may result in a fire.
• When mounting Inverters in an enclosure, install a fan or other cooling device to keep
the intake air temperature below 122°F (45°C) for IP20 (open chassis type), or below
105°F(40°C) for NEMA1 (TYPE1).
Overheating may cause a fire or damage the Inverter.
• The Inverter generates heat. For effective cooling, mount it vertically.
Refer to the figure in Mounting Dimensions on section 3.
