Warnings for UL/cUL M

a

rking

• 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 servicing the Inverter.

Then, wait at least one minute after the power supply is disconnected and all indicators are OFF.

• Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses semiconductors and is vulnerable to high voltage.

• Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never touch the printed control board (PCB) while the power supply is turned ON.

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

18,000 RMS symmetrical amperes, 250volts maximum (200V class units) or

18,000 RMS symmetrical amperes, 480volts maximum (400V class units).

CAUTION

(Ref. page)

Low voltage wires shall be wired with Class I Wiring.
