terminals cover.
LEDs indicating the power supply status:
– red LED – power output status:
OFF – normal operation, current consumption up to14 A,
flashing – overload, current consumption exceeds 14 A.
– yellow LED – battery status if the mode of operation with battery is enabled:
OFF – no battery or blown fuse of the battery charging circuit,
ON – battery OK,
flashing – low battery (battery voltage below 11.5 V or battery internal resistance
too high).
– green LED – AC power status:
ON – AC power OK,
flashing – no AC power or blown fuses of the AC circuit (battery operation).
– blue LED – flashing when the operating temperature exceeds 75°C (prolonged
high temperature may cause harm to the power supply).
If all LEDs are off when the 230 VAC power is connected, it means that the power
supply has been put into emergency mode as a result of shorting the power output to
ground – see section “Installation”.

In the normal state, the OC type outputs are shorted to ground (0 V), but when a trouble
occurs, the output is disconnected from ground.
2.2 Configuring the power supply
You can configure the power supply working parameters by using the DIP switches 1, 2, 4
and 5 (see Table 1). By factory default, all switches are set to OFF position.
Switch number Description
1
audible signaling of trouble
Enables (ON) / disables (OFF) the audible signaling of trouble
(short beep every 3 seconds).
2
operation with battery
Enables (ON) / disables (OFF) the mode of operation with
battery. When the mode of operation with battery is enabled, the
power supply is testing the battery state.
4
5
AC power failure reporting delay
Defines the time that must elapse after AC power loss before the
WS output turns on. The delay you can set according to Table 2.
Table 1.
If a battery is connected to the power supply, it is recommended that you enable the
mode of operation with battery. Thus, the backup supply operation will be supervised.

The switches 3 and 6 must be set to OFF position (Fig. 4).
3 Installation
Disconnect power before making any electrical connections.
Making connections with the power on may lead to blowout of the battery circuit
fuse or cause the power supply unit to enter emergency mode. To deactivate the
emergency mode, disconnect the 230 VAC power supply and reconnect it after
about 30 seconds.
The power supply should be connected to the 230 VAC mains supply. Before you connect
the power supply to AC power, familiarize yourself with the electrical installation of the facility.
Make sure that the circuit you choose for powering will be always alive. This circuit should be
protected by a suitable safety device.
As the backup power supply source, use a 12 V sealed lead-acid battery or other 12 V
battery with similar charging characteristics. The battery capacity must be selected to match
the system current consumption. If the battery is to meet the requirements of EN 50131 for
Grade 2, refer to the “Standard requirements for battery”.
After the battery voltage drops to 10.5 V, the battery will be disconnected to protect it against
deep discharge and damage.
Do not use batteries other than the recommended ones.
Do not connect a battery with less than 17 Ah capacity to the power supply.
The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
The sum of currents consumed by the devices to be supplied via the APS-1412 power supply
may not exceed:
12 A if a battery is connected to the power supply,
14 A if no battery is connected to the power supply.

1. Remove the screw securing the cover of power supply terminals (Fig. 5).
2. Remove the cover of power supply terminals (Fig. 6).
3. Use the DIP switches to configure the power supply (see “Configuring the power supply”).
4. If the power supply is to be integrated with a SATEL device, use the cable delivered with
the power supply to connect the power supply and the device. Pass the cable through the
opening in the enclosure (Fig. 7).
5. Connect devices to the power supply outputs (terminals +Vout and COM).
Remember that the cables connecting the + Vout power outputs to the devices
should be evenly loaded with current.
If you want to use the maximum power supply current of 14 A, connect the loads
so that each + Vout output supplies devices with a total current consumption of
about 5 A. To make connections, it is advisable then to use wires with
a minimum cross section of 1.5 mm2.
6. To the trouble signaling outputs, you can, for example, connect LEDs, relays, or connect
them to the inputs of control panel or other device which is to supervise the power supply
operation.
7. Connect the battery to the - BAT + terminals.
If the +Vout power supply outputs are loaded with 12 A current, it is
recommended that you use a minimum 4 mm2cross-section wires for battery
connection. The wires should be as short as possible.
8. Replace the cover of power supply terminals.
9. Replace and tighten the screw to secure the power supply terminals cover.
10.Connect the power cable to the power supply socket (Fig. 8).
11.Insert the power cable plug into the 230 VAC socket. The power supply will signal the
presence of voltage with 1 beep, and the LED will go on.

3 Standard requirements for battery
If the power supply is to be used in an alarm system which is to meet requirements of the
EN 50131 standard for Grade 2, the battery should provide 12 hours of system operation in
the event of mains power loss.
The power supply should ensure that the battery can be charged to 80% of its capacity in 72
hours. Tables 3 provides instructions on what battery to use so that the EN 50131
requirements for Grade 2 are met.
