all other equipment in the office to engineer the appropriate
aspects of the building.
The four categories of floor plan data relevant to battery plants
are listed below.
Floor Space: Space must be adequate for the battery plant
footprint and for aisles.
Floor Load: The building structure must support the intended
weight per unit floor area, and equipment must be spaced out to
distribute the load, as necessary.
Heat Load: The air conditioning and ventilation systems are
sized to maintain the environment given the heat dissipation of
the equipment.
AC Service: The ac distribution system is sized to accomodate
the current requirements of the powered equipment.
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 3-4.
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.
