2. Fire Prevention
CAUTION
Mount the inverter to incombustible material. Mounting it to or near combustible
material can cause a fire.
If the inverter has become faulty, switch off the inverter power. A continuous flow
of large current could cause a fire.
Do not connect a resistor directly to the DC terminals P(
+
), N(
−
). This could
cause a fire.
3. Injury Prevention
CAUTION
Apply only the voltage specified in the instruction manual to each terminal to
prevent damage etc.
Ensure that the cables are connected to the correct terminals. Otherwise,
damage etc. may occur.
Always make sure that polarity is correct to prevent damage etc.
While power is on and for some time after power-off, do not touch the inverter or
brake resistor as they are hot and you may get burnt.
4. Additional instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
(1) Transportation and installation
CAUTION
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the Instruction Manual.
Do not operate if the inverter is damaged or has parts missing.
When carrying the inverter, do not hold it by the front cover or setting dial; it may fall off
or fail.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent screws, wire fragments, other conductive bodies, oil or other flammable
substances from entering the inverter.
Do not drop the inverter, or subject it to impact.
Use the inverter under the following environmental conditions:
