Fire prevention
Injury prevention
b
CAUTION:
●
Mount the inverter to incombustible material. Install the inverter on a nonflammable
wall without holes (so that nobody can touch the inverter heatsink on the rear side,
etc.). 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.
●
When using a brake resistor, make up a sequence that will turn off power when an
alarm signal is output. Otherwise, the brake resistor may excessively overheat due
to damage of the brake transistor and such, causing a fire.
●
Do not connect a resistor directly to the DC terminals P/+, N/–. This could cause a
fire and destroy the inverter. The surface temperature of braking resistors can far
exceed 100°C for brief periods. Make sure that there is adequate protection against
accidental contact and a safe distance is maintained to other units and system
parts.

CAUTION:
●
Apply only the voltage specified in the instruction manual to each terminal. Other-
wise, burst, damage, etc. may occur.
●
Ensure that the cables are connected to the correct terminals. Otherwise, burst,
damage, etc. may occur.
●
Always make sure that polarity is correct to prevent damage, etc. Otherwise, burst,
damage, etc. may occur.
●
While power is on or for some time after power-off, do not touch the inverter as it
is hot and you may get burnt.
