2.6.2.2 Mx-4400V/LE & Mx-4800V
The diagrams opposite show the
recommended location and orientation
for the batteries within the panel for
17Ah, 25Ah and 38Ah batteries. The
diagram shows the arrangement for the
Mx-4800V .
The Mx-4400V/LE is only equipped with
the upper chassis. Batteries up to 38Ah
should be placed on the upper battery
shelf. Batteries up to 48Ah can be
supported
– these should be formed by
the parallel connection of 24Ah batteries
located on both battery shelves.
Note: A separate power supply chassis
can be fitted in the lower chassis position
to provide power and mounting positions
for peripheral options. Batteries for this
can be located at the bottom of the
enclosure.
For battery sizes greater than 12AH, it
will be necessary to remove the spade
terminals fixed to the battery leads and
replace these with connection fixings
suitable for the installed batteries.
Each battery shelf can hold batteries up
to 38Ah.

2.6.2.3 Battery Temperature Monitoring
Each of the base cards contains an on-
board thermistor device to monitor the
temperature in the enclosure.
For the Mx-4200 / Mx-4400 standard
enclosures, this on-board thermistor is
ideally situated to monitor the
temperature of the batteries.
As the batteries installed in the Mx-4800
and Mx-4400/LE enclosures are located
remote from the on-board sensor then
the temperature gradient in the panel
may result in an incorrect charging
voltage (too low) being applied
(depending on panel loading and internal
heating effects).
A separate plug-in thermistor assembly
should be used on the Mx-4800 and Mx-
4400/LE (supplied with these panels).

To use the plug-in thermistor:
Remove the jumper from, and plug-in the thermistor cable
assembly to, the connector shown above. Route the
thermistor cable assembly along with the battery wires and
use the supplied tie-wrap to hold the thermistor sensor
close to the top of the batteries.
DO NOT remove the jumper when an external thermistor is
not employed.
