This section is specifically about safety matters
Do not attempt to install, operate, maintain or inspect the converter unit until you have read through this Installation Guideline and
appended documents carefully and can use the equipment correctly. Do not use the product until you have a full knowledge of the
equipment, safety information and instructions.
Installation, operation, maintenance and inspection must be performed by qualified personnel. Here, qualified personnel means person-
nel who meets all the conditions below.
A person who took a proper engineering training. Please note if you can take a proper engineering training at your local Mitsubishi Electric
office. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations.
A person who can access operating manuals for the protective devices (e.g. light curtain) connected to the safety control system.
A person who has read and familiarized himself/herself with the manuals.
In this Installation Guideline, the safety instruction levels are classified into "WARNING" and "CAUTION".
WARNING
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
CAUTION
cause physical damage only.
Note that even the
CAUTION
of both levels because they are important to personnel safety.
Electric Shock Prevention
While the converter power is ON, do not open the front cover or the wiring cover. Do not run the converter with the front cover or the wiring
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 converter circuits
and get an electric shock.
Before starting wiring or inspection, check to make sure that the operation panel indicator 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.
A neutral-point earthed power supply for converter unit in compliance with EN standard must be used.
Any person who is involved in the wiring or inspection of this equipment should be fully competent to do the work.
Always install the converter unit 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. Otherwise you may get 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 replace the cooling fan while power is on. It is dangerous to replace the cooling fan while power is on.
t touch the printed circuit board or handle the cables with wet hands. You may get an electric shock.
Do no
Fire Prevention
Mount the converter unit to incombustible material. Install the converter unit on a nonflammable wall without holes (so that nobody
can touch the converter unit heatsink on the rear side, etc.). Mounting it to or near combustible material can cause a fire.
If the converter unit has become faulty, switch off the converter unit power. A continuous flow of large current could cause a fire.
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.
Injury Prevention
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 converter unit as it is hot and you may get burnt.
level may lead to a serious consequence according to conditions. Please follow strictly the instructions
