Grounding Rail
The Sidecar enclosure contains an Input Power Panel (IPP), one or two Service Power Inserters
(SPI),and the Enclosure Grounding Rail. The Power Supply rests on the upper shelf, and a
36 or 48 VDC battery pack on the lower two shelves.
A cooling fan is required any time a Power Supply is housed in the side car. The
fan is thermostatically controlled to turn on at ~140 deg F and off at ~110 deg
F. The fan cable has a 'T' connector that attaches to the Power Supply output
connection. Replace fuse only with a 1/4” X 1-1/4”, 5 Amp, 250 Volt
