PRECAUTIONS FOR UL/cUL MARKING

• Do not connect or disconnect wiring, or perform signal checks while the

power supply is turned ON.

• The Inverter internal capacitor is still charged even after the power supply

is turned OFF. To prevent electric shock, disconnect all power before ser-

vicing the Inverter, and then wait at least one minute after the power sup-

ply is disconnected. Confirm that all indicators are OFF before

proceeding.

• Do not perform a withstand voltage test on any part of the Inverter. The

Inverter is an electronic device that uses semiconductors, and is thus vul-

nerable to high voltage.

• Do not remove the Digital Operator or the blank cover unless the power

supply is turned OFF. Never touch the printed circuit board (PCB) while

the power supply is turned ON.

• This Inverter is not suitable for use on a circuit capable of delivering more

than 18,000 RMS symmetrical amperes, 250 V maximum (200 V Class

Inverters) or 18,000 RMS symmetrical amperes, 480 V maximum (400 V

Class Inverters).

PRECAUTIONS FOR CE MARKINGS

• Only basic insulation to meet the requirements of protection class 1 and

overvoltage 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 con-

form to CE requirements.

• For conformance to EMC directives, refer to the relevant manuals for the

requirements.

Document No. EZZ008389 for Japanese version,

Document No. EZZ008390 for English version

• Use 75°C copper wire or equivalent.

Low voltage wires must be wired with Class I Wiring.
