(INPUT)
The total cumulative sum of the 24VDC output (power limited + non-power limited)
must not exceed 12A. Over current draw will initiate a PSX-12C shut down.
The main AC power line must be turned OFF prior to installation.
Normally OFF . When illuminated, indicates
that the 24VDC non-power limited output
has a trouble condition or the PSX-12C
has disconnected the 24VDC output due
to current overload or short circuit.
Normally OFF . When illuminated, indi-
cates that the 24VDC power limited
output has a trouble condition or the
PSX-12C has disconnected the 24VDC
power output due to current overload or
short circuit.
24VDC Power Limited Output Terminal. This terminal
output is limited to 4A. When it is exceeded, it will shut
down, light its associated diagnostics LED and send a
fault condition to the
PMI-S.
This output is normally connected to the modules and
cards located on the door of the enclosure or to the
remote CAN network modules. This output is power
limited to NFPA 70 per 760. All wiring must be in
accordance with Article 760 of NEC or local building
codes. (See Figure 2.)
Output Voltage: 24VDC +10%, -15%
Output Current: 4A max

24VDC Non-Power Limited Output Terminal. This
terminal is non-power limited and can supply up to 12A.
When the current draw is exceeded, it shuts down,
lights its associated LED and sends a fault condition to
the PMI-S.
This output is normally connected to the input terminals
of the CC-5. All wiring must be in accordance with
Article 760 of NEC or local building codes. (See Figure 2.)
