NEC IP8800/S6700, IP8800/S6600, IP8800/S3600, IP8800/S2400 manual Do not use power not specified

Safety Guide [IP8800/S3600] [IP8800/S2400]

■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.

•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.

•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.

•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.

■Before installing or removing a DC power cable, turn off the breaker on power supply 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.
