Precautions for Operation
Before Turning ON Power
CAUTION
Choose the appropriate power source with correct voltage settings for the input
voltage specification of the Inverter.
WARNING
Special care must be taken while wiring the primary circuitry panel. The L1, L2 and L3
terminals must be connected to the input power source and must not be mistakenly
connected to T1, T2 or T3 output terminals. This may damage the Inverter when the
power is turned ON.
CAUTION
z
Do not attempt to transport the Inverter by the front cover. Securely hold the
Inverter by the heatsink mounting chassis to prevent the Inverter from falling.
Failure to do so may cause personal injury or damage to the Inverter.
z
Install the Inverter onto a firm metal baseplate or a non-flammable type material.
Do not install the Inverter onto or nearby any flammable material.
z
An additional cooling fan may need to be installed if several Inverters are installed
into one control panel. The temperature inside an enclosed panel should be below
104
o
F (40
o
C) to avoid overheating.
z
Turn OFF the power supply before performing any work in the control panel. Carry
out installation procedures according to instructions. This will help avoid a situation
that may result in an operational malfunction.
