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.). Mount-
ing 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.
●
Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If a
product is used without any inspection, a burst, breakage, or a fire may occur.

CAUTION:
●
Apply only the voltage specified in the instruction manual to each terminal. Otherwise,
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.
