3.2.2.7 Remote Temperature Sensor
Provision is made on the 3.0A and 5.0A PSE
models for the connection of a remote battery
temperature sensor (Mxp-501). This is for
applications where the modules are installed in
rack mount enclosures or in large enclosures and
where the batteries are not located immediately
next to the module.
A latching pin header, PL3, is provided for
connection of the temperature sensor
– see
opposite and below.
If a remote temperature sensor is not used,
ensure the jumper is fitted to the centre two pins.

If neither a jumper nor a remote sensor is fitted, the PSE
module will indicate a charger fault condition.
Remove the jumper and plug the Mxp-501 into the connector. Route the sensor cable along with the battery
leads. Use the supplied tie-wraps to tie the sensor cable to the battery leads so that the encapsulated sensor is
located close to the batteries. The sensor cable is 500mm in length.
