Prerequisites for the Installation

Warning

Statement 1028 More Than One Power Supply

This unit might have more than one power supply connection. To reduce risk of electric shock, all connections

must be removed to de-energize the unit.

Warning

Statement 1030 Equipment Installation

Only trained and qualified personnel should be allowed to install, replace, or service this equipment.

Warning

Statement 1024 Ground Conductor

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or

operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical

inspection authority or an electrician if you are uncertain that suitable grounding is available.

Warning

Statement 1046 Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be

made first and disconnected last.

Warning

Statement 445 Connect the Chassis to Earth Ground

To reduce the risk of electric shock, the chassis of this equipment needs to be connected to permanent earth

ground during normal use.

Warning

Statement 338 Prevent Accidental Discharge

To prevent accidental discharge in the event of a power line cross, route on-premise wiring away from power

cables and off-premise wiring, or use a grounded shield to separate the on-premise wiring from the power

cables and off-premise wiring. A power line cross is an event, such as a lightning strike, that causes a power

surge. Off-premise wiring is designed to withstand power line crosses. On-premise wiring is protected from

power line crosses by a device that provides overcurrent and overvoltage protection. Nevertheless, if the

on-premise wiring is in close proximity to or not shielded from, the off-premise wiring or power cable during

a lightning strike or power surge, the on-premise wiring can carry a dangerous discharge to the attached

interface, equipment, or nearby personnel.
