If you must inspect the circuitry while the power is

on, do not touch the live parts.

(Failure to observe this warning may

result in electric shock.)

Check insulation

Upon completing repair work, always measure the insula-

tion resistance. Verify that it is at least 10 MΩ(with a 500

V DC insulation resistance tester), and then turn on the

power.

(Inadequate insulation may result in

electric shock.)

Improper handling of the product may

result in serious injury or death.

Caution Improper handling of the product may result in injury or

damage to properties including buildings and equipment.

may result in electric shock and/or fire.)

Replace damaged and/or degraded parts

Be sure to replace the power cord and lead wires if

they are damaged and/or degraded.

(Failure to observe this warning may

result in electric shock and/or fire.)

Use proper parts and tools

For repair, be sure to use the parts listed in the parts

catalog of the applicable model and use the proper

tools.

(Failure to observe this warning may

result in electric shock, fire and/or injury.)

Caution against

electric shock

Prohibited

Turn off the power supply

Be sure to shut off the circuit breaker before

disassembling the unit for repair.

(Failure to observe this warning may

result in electric shock.)

Make sure that the product operates properly upon completion of repair. Clean the product and the surrounding

area, and then notify the customer of the completion of repair.

Caution for injury
