Description of terminals:
230
and
AC
–
mains power supply inputs (230 V AC).
+U
–
power supply outputs (27.2
–27.6 V DC)
. Total current capacity of outputs
5 A.
COM
–
common ground (0V).
AWT
–
alarm output (OC): excessive permissible working temperature.
AWB
–
alarm output (OC): low battery voltage – below 22 V.
AWP
–
alarm output (OC): excessive permissible overload current – current
consumption over 5 A.
AWS
–
alarm output (OC): loss of 230 V
AC – output activation delay 1800 s or
10 s.
2. Installation
Prior to commencement of installation, load balance of the power supply should be drawn up.
The current derived from the APS-524 by external devices must not exceed 5 A.
The power supply should only operate while being permanently connected to mains supply.
Hence, before making the connections it is necessary to familiarize with the electric system in
the facility. For powering the device choose the circuit which is always live. The power supply
circuit should be protected with a proper fuse.
Before connecting a device to the power supply circuit from which it will be
powered, make sure the circuit is not alive.
1. Attach the mounting (plastic) pins to the back side of the housing.
2. Mount the power supply housing in selected location and connect all electric leads .
3. Put the APS-524 board on the pins.
4. Fix the LED board to the housing lid with two steel sheet metal screws
(green LEDs in
upward position).
5. Connect the 230 V AC power wires to the 230 V and AC terminals of the APS-524.
Connect the grounding wire to the terminal situated inside, on the rear panel of the metal
housing and marked by the ground symbol
.
6. Connect the supply cables for external devices to the terU and COM on the APS-
524 board.
7. If necessary, make use of the trouble signaling outputs (e.g. to control relays or connect
to the control panel zones).
