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.
