Mitsubishi Electric FR-V500 Instruction Manual page 2

Thank you for choosing this Mitsubishi vector inverter. This Instruction Manual (detailed) provides instructions for advanced use of the
FR-V500 series inverters. Incorrect handling might cause an unexpected fault. Before using the inverter, always read this Instruction
Manual and the Instruction Manual (basic) [IB-0600064] packed with the product carefully to use the equipment to its optimum
performance.
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. 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
CAUTION
Note that even the
both 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 or 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 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 codes. (NEC section 250, IEC 536 class 1 and other applicable standards).
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
Install the inverter on an incombustible wall without holes, etc. 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.
When a brake resistor is used, use an alarm signal to switch power off. Otherwise, the brake resistor will overheat abnormally due to
a brake transistor or other fault, resulting in 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 or brake resistor as they are hot and you may get burnt.
4. Additional Instructions
Also note the following points to prevent an accidental failure, injury, electric shock, etc.
1) Transportation and installation
When carrying products, use correct lifting gear to prevent injury.
Do not stack the inverter boxes higher than the number recommended.
Ensure that installation position and material can withstand the weight of the inverter. Install according to the information in the
instruction manual.
Do not operate if the inverter is damaged or has parts missing.
When carrying the inverter, do not hold it by the front cover; it may fall off or fail.
Do not stand or rest heavy objects on the inverter.
Check the inverter mounting orientation is correct.
Prevent screws, wire fragments, other conductive bodies, oil or other flammable substances from entering the inverter.
Do not drop the inverter, or subject it to impact
Use the inverter under the following environmental conditions:
Ambient temperature
Ambient humidity
Storage temperature
Ambience
Altitude, vibration
*Temperature applicable for a short time, e.g. in transit.
