Safety Instructions; Fire Prevention - Mitsubishi Electric FR-A500L Series Instruction Manual

SAFETY INSTRUCTIONS

1. Electric Shock Prevention
While power is on or when the inverter is running, do not open the front door. You may get an electric
shock.
Do not run the inverter with the front door opened. Contact with the exposed high-voltage terminals or
charging part of circuitry will cause an electric shock.
If power is off, do not open the front door except for wiring or periodic inspection. You may access the
charged inverter circuits and get an electric shock.
Before starting wiring or inspection, switch power off, wait for more at least 10 minutes and check for the
presence of any residual voltage with meter (see chapter 2 for-further details.) etc.
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.
Operate the switches 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.

2. Fire Prevention

Install the inverter on an incombustible cubicle. 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.
Do not connect the 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.
After the inverter has been operating for a relatively long period of time, do not touch the inverter as it
may be hot and you may get burnt.
