2000 ECS/GPS Battery Plant J85500G-2
3 - 24 Engineering, Planning and Ordering
Issue 6 May 1999
AC Service: The ac distribution system is sized to accomodate
the current requirements of the powered equipment.
Cable Rack and
Routing
To help plan for the routing and support of battery plant cabling,
typical arrangements are shown in Figure 3-4.
Grounding
The ECS battery plant is designed for compatability with most
grounding systems. The standard dc discharge return bus is
located in the initial bay. Alternatively, the battery plant return
bus system may be mounted in the overhead cable rack.
When the discharge return bus is in the initial bay, a connection
point is provided on it specifically for grounding. This point may
be used to tie the battery plant to the building grounding
electrode. Two holes for .250-20 self tap screws are provided at
the rear of the top crossmember of the bay uniframe to
accommodate a two-hole cable lug on .62" centers. If the frame
ground lead is calculated to be larger than 2 AWG, the
corresponding lug has 3/8" diameter holes on 1" centers. In this
case, the adapter that is always provided with the bay should
always be used. Refer to Figure 3-5.
Growth
Building systems should be designed for ultimate growth. Cable
rack support and ac distribution cabinets should be sized for the
maximum anticipated battery plant capacity. Floor space and
weight capacity should also account for any increase in battery
reserve.
Ordering
Reference
Material
This manual contains all the needed planning and ordering
information for the ECS Battery Plant J85500D-3. Some
customers may prefer to prepare plans and orders from
manufacturing, wiring and schematic drawings. Read the
following sections to learn how to order Lucent Technologies
equipment from these drawings.
Coding and
Terminology
The two main categories of Lucent Technologies hardware are
called apparatus and equipment. The battery plant ordering
process primarily involves equipment for the system and
apparatus for components and replacements.
