■ Do not use power not specified.
• Do not use a supply voltage not specified. Fire disasters or electric shock may be caused.
■ The current capacity supplied to the power distribution panel must be larger than the
operating current of the breaker.
operating current of the breaker.
• The current capacity supplied to the power distribution panel must be larger than the operating current of
the breaker. Otherwise, the breaker may not work in the event of a failure and cause fire disasters.
■ Grounding is required.
• For the AC power supply model, AC power supply (PoE) model, redundant power supply model (with AC
power supplies mounted), and external power unit (EPU), be sure to use a grounded outlet. If the power
supply is used without grounding, electric shock may be caused and failures may occur due to electric
noise.

noise.
• For the DC power supply model and redundant power supply model (with DC power supplies mounted),
be sure to use a grounding cable. If the power supply is used without grounding, electric shock may be
caused and failures may occur due to electric noise.

• 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 and fire disaster.
■ Attach insulation covers on the G terminal and -48V terminal of a DC power cable.
• Attach insulation covers on the G terminal and -48V terminal of a DC power cable (the side of which
connects to power supply facilities). Operation without insulation covers may cause electric shock.
■ Observe the specified margin of length when ripping the power cable sheath.
• When using the -48VDC power cable for the redundant power supply model, rip the power cable sheath
(on the device side) with the margin of 8 to 10 mm (0.3 to 0.4 in)..
If the margin is too small, loose connection or cable disconnection may be caused. On the other hand, too
large margin may cause conductor exposure, resulting in electric shock.
