Power Plug And Power Cord Precautions - Ricoh D117 Service Manual

Power Plug and Power Cord
Before serving the machine (especially when responding to a service call), always make

sure that the power plug has been inserted completely into the power source. A partially
inserted plug could lead to heat generation (due to a power surge caused by high
resistance) and cause a fire or other problems.
Always check the power plug and make sure that it is free of dust and lint. Clean it if

necessary. A dirty plug can generate heat which could cause a fire.
Inspect the length of the power cord for cuts or other damage. Replace the power cord if

necessary. A frayed or otherwise damaged power cord can cause a short circuit which
could lead to a fire or personal injury from electrical shock.
Check the length of the power cord between the machine and power supply. Make sure

the power cord is not coiled or wrapped around any object such as a table leg. Coiling the
power cord can cause excessive heat to build up and could cause a fire.
Make sure that the area around the power source is free of obstacles so the power cord

can be removed quickly in case of an emergency.
Make sure that the power cord is grounded (earthed) at the power source with the ground

wire on the plug.
Connect the power cord directly into the power source. Never use an extension cord.

When you disconnect the power plug from the power source, always pull on the plug, not

the cable.
