CAUTION

z Make sure the input power is off before wiring.
z When power supply is switched off following operation, wait at least 10

minutes after LED keypad display is off before you start working on it. If
tester is available, check the voltage between P1 and N terminals. Wiring

should be performed after verifying that input voltage in inverter DC circuitry
is all exhausted.

z Applying input power supply to the output terminals U, V and W causes

internal inverter damage.

z Use ring terminals with insulated caps when wiring the input power and motor

wiring.

z Do not leave wire fragments inside the inverter. Wire fragments can cause

faults, breakdowns and malfunctions.

z Never short P1 or P and N terminals. Shorting terminals may cause internal

inverter damage.

z Do not install a power factor capacitor, surge suppressor or RFI filters in the

output side of the inverter. Doing so may damage these components.
