Mitsubishi FR - S500 instruction manual

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.

4. Additional instructions

Also note the following points to prevent an accidental failure, injury, electric shock, etc.

(1) Transportation and installation

CAUTION

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 or setting dial; 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	-10°C to +50° C (14° F to 122° F) (non-freezing)
	temperature
	Ambient humidity	90%RH or less (non-condensing)
Environment	Storage	-20°C to +65° C * (-4°F to 149° F)
	temperature
	Ambience	Indoors (free from corrosive gas, flammable gas,
		oil mist, dust and dirt)
		Maximum 1000m (3280.80feet) above sea level for
		standard operation. After that derate by 3% for
	Altitude, vibration	every extra 500m (1640.40feet) up to 2500m
		(8202.00feet) (91%).
		5.9m/s2 or less (conforming to JIS C 0040)
*Temperatures applicable for a short time, e.g. in transit.
		A-2
