Thank you for choosing this Mitsubishi transistorized inverter option unit. This instruction manual provides
handling information and precations for use of the equipment. Before using the inverter option, always read
this instruction manual carefully to use the equipment to its optimum.
Please forward this instruction manual to the end user.
This instruction manual uses the International System of Units (SI). The measuring units in the yard and
pound system are indicated in parentheses as reference values.
1. Electric Shock Prevention
2. Fire Prevention
3.Injury Prevention
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you have read through the instruction
manual and appended documents carefully and can use the equipment correctly.In this instruction manual, the
safety instruction levels are classified into "WARNING" and "CAUTION"
.
Assumes that incorrect handling may cause hazardous conditions, resulting in
death or severe injury.
Assumes that incorrect handling may cause hazardous conditions, resulting in
medium or slight injury, or may cause physical damage only.
Note that even the level may lead to a serious consequence according to conditions. Please
follow the instructions of both levels because they are important to personnel safety.
z While power is on or when the inverter is running, do not open the terminal block cover. You may get an
electric shock.
z Do not run the inverter with the terminal block cover removed. Otherwise, you may access the exposed
high-voltage terminals or the charging part of the circuitry and get an electric shock.
z Before starting wiring or inspection, switch off power, check to make sure that the charge lamp is off, wait
for at least 10 minutes after the power supply has been switched off, and check that there are no residual
voltage using a tester or the like. The capacitor is charged with high voltage for some time after power off
and it is dangerous.
z Earth (ground) the inverter.
z Any person who is involved in wiring or inspection of this equipment should be fully competent to do the
work.
z Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured.
z Perform setting dial and key operations with dry hands to prevent an electric shock.
z Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may get
an electric shock.
z Mount the power regeneration common converter unit and dedicated stand-alone reactor unit to
incombustible material. Mounting it to or near combustible material can cause a fire.
z Do not connect a resistor directly to the DC terminals P/L+, N/L-. This could cause a fire.
z Apply only the voltage specified in the instruction manual to each terminal to prevent damage etc.
z Ensure that the cables are connected to the correct terminals. Otherwise damage etc. may occur.
z Always make sure that polarity is correct to prevent damage etc.
z While power is on and for some time after power-off, do not touch the power regeneration common
converter unit and dedicated stand-alone reactor unit as they are hot and you may get burnt.
zWhen changing the fan, take care not to get injured.
