ture. The sensor is conveniently encapsulated with thermally conductive epoxy
in an isolated copper lug which may be mounted directly to a battery terminal
or affixed to the side of a battery. Route the sensor cable to the MPT-3024 and
through a knockout in the enclosure, using a cable clamp or suitable bushing.
Plug the sensor cable’s connector into the matching jack on the circuit board.
Although the MPT-3024 includes noise-canceling circuitry, it is best not to run
the sensor’s cable near any possible sources of electrical noise, such as house
wiring or fluorescent light fixtures.
!
Connecting the sensor to the MPT-3024 while the power is on may
cause erratic operation, but will cause no damage – plug the sensor in only
when power is disconnected from the unit. Use only the supplied tempera-
ture sensor with the MPT-3024. Using other sensors, or attempting to plug
telecommunications equipment into the temperature sensor’s jack may
damage the MPT-3024 and will void the warranty.
11.8 Remote battery voltage sense connection
A 15-foot twisted-pair cable is included with the MPT-3024. One end of this
cable has tinned leads — connect the black wire from this end to the “-”
screw on the SNS terminal block in the MPT-3024, and the red wire to the
“+” screw (see Figure 11.2.1). The other end of this cable has ring terminals
installed — connect these to your battery bank. The black wire is negative,
and the red wire is positive. For most accurate measurement, the wires from
this cable should connect to your battery bank at the same posts where
power is taken off of the bank.
!
Always make the connection to the MPT-3024 SNS terminal block
before making the connection to your battery bank. If it becomes necessary
to disconnect this cable, always remove it from the battery bank
before
disconnecting it from the controller.
S
The MPT-3024 requires a correctly polarized connection to the SNS
terminal block for proper operation. Reverse polarity at the SNS terminal
block won’t damage the unit, but the unit won’t initialize without a properly
polarized connection.
