To meet surge protection requirements, the shield on any open-ended cable must be
grounded by attaching the shield to a convenient chassis ground point, using hardware
suitable to provide a solid electrical and mechanical connection. In addition, ensure that
there is sufficient strain relief to remove any mechanical strain on the ground connection
due to cable movement.
The intra-building port(s) of the equipment or sub-assembly is suitable for connection to
intra-building or unexposed wiring or cabling only. The intra-building port(s) of the
equipment or sub-assembly must not be metallically connected to interfaces that connect
to the Outside Plant (OSP) or its wiring. These interfaces are designed for use as intra-
building interfaces only (Type 2 or Type 4 ports as described in GR-1089-CORE) and
require isolation from the exposed OSP cabling. The addition of primary protectors is not
sufficient protection in order to connect these interfaces metallically to OSP wiring.
Connection to external OSP wiring must be made through an external CSU prior to
exiting the building.
Bare conductors must be coated with an appropriate antioxidant compound before crimp
connections are made. All unplated connectors, braided strap, and bus bars must be
brought to a bright finish and then coated with an antioxidant before they are connected.
The 7705 SAR-F is suitable for both DC-I and DC-C power configurations. However,
when used in a DC-I configuration, the battery returns must remain isolated until they
reach the main power bus.
Only electrical service personnel should perform wiring and cabling to the system.
Power cable(s) must meet local electric code requirements.
All power to the equipment rack or cabinet should be disconnected before the installation.
An external circuit breaker or fuse with a minimum 5 A and maximum 10 A rating must be
located within a readily accessible distance from the equipment. This is intended as the
disconnect device.
When removing DC power cables from the system, first disconnect the power from the
source and then disconnect the cables from the 7705 SAR-F.
