ELECTRICAL CONNECTIONS
This section gives an overview of the external connections that are made to the
SDB670 Base Station. It also provides details of the pin-outs for these connections.
GENERAL
All cabling should be installed so that the equipment can be accessed for servicing
purposes without straining the cables or connectors used.
Where equipment is rack mounted, cables must be run so that the unit can be fully
withdrawn on its runners without straining, catching or pinching any of the cables.
Cables should be dressed into cable trays etc where available and run so as to reduce
likelihood of damage from vermin or adverse environments.
Multi-strand wires must be used wherever the wire will be flexed by accessing the
equipment.
