3.2.2.4 Remote LED indication:
A pin header, J1, provides a means for remote/ external
indication of “Power” and “Fault” indications.
The Mxp-049, Mxp-050 & Mxp-051 models are supplied
fitted with separate Green and Amber LED Indicators.
Refer to diagram below for how to connect these
assemblies to the PSU.
Replacement parts are available. Green = Mxs-026-GRN
and Amber = Mxs-026-YEL
The Mxp-549, Mxp-550 & Mxp-551 are supplied with an
LED PCB mounted on the cover. This is connected to the
PSE module using a 4-Way cable.

The Green “Power” indicator will be ON continuously
when the power supply is being supplied with mains
power. This indicator will flash when the mains supply is
off and the power supply is being powered from its
battery source.
The Amber “Fault” indicator will be ON continuously if
any of the Fault conditions listed opposite are present:
Note: Faults may not be indicated immediately. They will
be indicated within the times permitted in EN54-4 (see
opposite for nominal times).
