ALARM TEXT LABELS
The 1S25 front panel has provision for custom text to identify the
sensor location for each arc fault tripping zone. The required text
may be engraved on the front panel by the factory if specified at
time of order. Alternatively the front panel may be removed for
engraving by the user or contractor. The RMS web site provides
an ACAD file for this purpose.
The front panel is fabricated from flexible plastic sheet with a
white surface & black substrate to provide high contrast black
text when engraved.
Removal of the front label is achieved by drawing out the 1S25
module from the outer case & pulling the label from the edges at
the mid point between the top & bottom draw out handles. This
will cause the label to bend & disengage from the top & bottom
handle retention points. Once free from the 1S25 module the
front label can be placed on an engraving table. Additional factory
engraved labels may be sourced from RMS for later field
installation.
While an engraved label provides the most permanent record
other methods such as laser printed stick on labels or indelible
marker pen may be satisfactorily employed.

labeling information with the 1S25 product ordering code. For

characters.
Text will be left justified.

CONFIGURATION CODE
(Optional specification)
The configuration code can be set in the field by withdrawing the
relay module & following the instructions on the side plate label.
The configuration code may be specified at time of order so that
the relay will be shipped from the factory pre-set to meet
customer requirements. e.g. CONFIG-0101-0101-1111
If a configuration code is not specified the factory default will be
set as indicated below. i.e. CONFIG-1111-1111-1111
