Mitsubishi Electronics FR-V500 instruction manual Electric Shock Prevention

This Instruction Manual (basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (basic) to the end user.

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 (basic) and appended documents carefully and can use the equipment correctly. In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION".

WARNING

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 CAUTION level may lead to a serious consequence according to conditions. Please fol- low the instructions of both levels because they are important to personnel safety.

1. Electric Shock Prevention

WARNING

!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-volt- age terminals or the charging part of the circuitry and get an electric shock.

!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 that power lamp display is turned off and check for residual volt- ages with a meter etc. more than 10 minutes after power-off.

!Earth (Ground) the inverter.

!Any person who is involved in 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. It is dangerous to change the cooling fan while power is on.

2. Fire Prevention

CAUTION

!Mount the inverter to incombustible material. 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.

!Do not connect a resistor directly to the DC terminals P, N. This could cause a fire.

3.Injury Prevention

CAUTION

!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 or brake resistor as they are hot and you may get burnt.
