Mains Power Connection
Only appropriately qualified and trained personnel can install and service this equipment.
Mains Power must be connected in accordance with local national wiring rules and
regulations. Building installation shall provide appropriate short-circuit backup protection
rated not higher than 20 A and with a breaking capacity of at least 1500 A.
Always remove input mains voltage (by disconnecting power cord from the mains power
outlet or by switching off an external circuit breaker, depending on installation) before
performing any operation on this product. Failure to do so may cause fire and may result in a
serious personnel injury or even death.
Disconnect power cord from the Power Supply Module and wait for its LEDs on the front
panel to go OFF before wiring, removing or servicing.
Warning
For PERMANENTLY CONNECTED EQUIPMENT, a readily
accessible disconnect device shall be incorporated in the building
installation wiring.
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed
near the equipment and shall be easily accessible.
Earth / Ground Conductors
Earth / Ground conductors should be connected in a tree fashion with branches routed to a
central earth ground point. This ensures that no ground conductor carries current from any
other branch. This method is shown in the following figure.
Recommended System Grounding
Earth / Ground conductors should be as short and as large in size as possible. Braided
straps or ground cables (typically green insulation with a yellow tracer - AWG #12 / 5 mm
2
or
larger) can be used to minimise resistance. Conductors must always be large enough to
carry the maximum short circuit current of the path being considered.
