■ Grounding is required.
• When the device is connected to the power supply of 100VAC, leak current of up to 3.5mA flows for each
device. Be sure to use the grounded outlet. If the power supply is used without grounding, an electric shock
may be caused and failures may occur due to electric noise.
may be caused and failures may occur due to electric noise.
• When the device is connected to the power supply of 200VAC, leak current of up to 5mA flows for each
device. Choose a grounded outlet and make sure that the outlet is grounded to a ground plate in the
building. Request the maintenance personnel or specialized installation workers to check the grounding. If
the power supply is used without grounding, an electric shock may be caused and failures may occur due
to electric noise. The label below is attached to the device.

engineer or maintenance personnel.
• Installing/uninstalling of the DC power cable must be performed by the trained engineer or maintenance
personnel. DC power cable is connected to the power supply via a terminal. Therefore, inadvertent
handling of the DC power cable may result in fire disasters or electric shock.

facilities.
• Before installing or removing a DC power cable, turn off the breaker on power supply facilities. Operation
with the breaker on may cause electric shock.
■ Attach insulation covers on the 0V and -48V terminals of a DC power cable.
• Attach insulation covers on the 0V and -48V terminals of a DC power cable (the side of which connects to
power supply facilities). Operation without insulation covers may cause electric shock.
■ When using the DC power supply, do not leave the terminal board uncovered.
• When using the DC power supply, be sure to attach the cover to the terminal board after connecting the
power cable. Operating it without the terminal board cover can cause an electric shock.
■ Do not touch the potential tap.
• The power supply is provided with the potential tap. This tap is used for inspection at shipment. Customer
should not use this tap. Do not insert a sharp material such as pin or clip into the potential tap. Fire disasters
or electric shock may be caused.
