Brother 4000CN User Manual page 23

To prevent fire or electric shocks, connect the green earth wire bundled with the
power cord to one of the following:
• The earth terminal of the power outlet
• A piece of copper buried in the earth 650 mm or deeper
Make sure that the earth wire on the power cord is connected before you use
the printer. If it is not possible to make an earth connection, consult your dealer
or Brother authorized service representative.
Never connect the earth wire to any of the following:
• Gas pipes that could ignite and explode
• Telephone line earth wires or lightning rods, which can draw an excessive
electric current if hit by lightning
• Water faucets or pipes whose electrical conductivity is broken by a
non-metallic part
If the power cord is broken or insulated wires are exposed, ask your dealer or
authorized Brother service representative. Using a damaged cord can cause fire
or electric shocks.
Do not plug or unplug the printer when it is on. Unplugging a live connector can
deform the plug and cause fire.
When unplugging the printer, grasp the plug instead of the power cord. Forcibly
pulling the power cord can damage it and cause a fire or electric shocks.
Be sure to turn off and unplug the printer before accessing the interior of the
printer for cleaning, maintenance, or troubleshooting. Accessing the interior of a
live printer can result in electric shocks.
Once a month, turn off the printer and check the power cord for the following. If
you notice any unusual conditions, contact your dealer for assistance.
• The power cord is plugged firmly into the power outlet.
• The plug is not excessively heated, rusted, or bent.
• The plug and outlet are dust free.
• The cord is not cracked or frayed.
