Thank you for choosing this Mitsubishi transistorized Inverter.
This instruction manual gives handling information and precautions for use of this equipment.
Incorrect handling might cause an unexpected fault. Before using the inverter, please read this manual carefully to use the
equipment to its optimum.
Please forward this 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.
This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the inverter until you have read through this instruction manual and
appended documents carefully and can use the equipment correctly.
Do not use the inverter until you have a full knowledge of the equipment, safety information and instructions.
In this instruction manual, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
CAUTION
Note that the
CAUTION
levels because they are important to personnel safety.
1. Electric Shock Prevention
While power is on or when the inverter is running, do not open the front cover. You may get an electric shock.
Do not run the inverter with the front cover removed. Otherwise, you may access the exposed high-voltage terminals or the
charging part of the circuitry and get an electric shock.
Even if power is off, do not remove the front cover except for wiring or periodic inspection. You may access the charged inverter
circuits and get an electric shock.
Before starting wiring or inspection, check to make sure that the inverter power indicator 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.
This inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local safety
regulations and electrical code. (JIS, NEC section 250, IEC 536 class 1 and other applicable standards)
Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
Always install the inverter before wiring. Otherwise, you may get an electric shock or be injured.
Perform setting dial and key operations with dry hands to prevent an electric shock.
Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise, you may get an electric shock.
Do not change the cooling fan while power is on. To do so will invite a hazardous condition.
2. Fire Prevention
Mount the inverter on an incombustible surface. Installing the inverter directly on or near a combustible surface could lead to 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.
3. Injury Prevention
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 as it is hot and you may get burnt.
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.
level may lead to a serious consequence according to conditions. Please follow the instructions of both
