WARNINGS 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 turnd 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 indecators 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.
• This 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).
Use 75°C copper wires or equivalent.
Low voltage wires shall be wired with Class I Wiring.
WARNINGS 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
conform to CE requirements.
• For conformance to EMC directives, refer to the relevant manuals for the
requirements.
