READ THIS FIRST!
100 mm free space must be left on the top and bottom.
Electronics, regardless of enclosure, are intended for use in a controlled indoor envi-
ronment.
Ventilation must not be covered.
Only authorized persons should install and maintain the system.
It is the installer's responsibility to ensure that the system is suitable for its intended
use.
Documents accompanying the system must be kept in or in its immediate vicinity.
Mains voltage should be disconnected during installation.
All information subject to change.
Upon installation of this product, the installer acknowledges and accepts the limitations
of this product as described in this manual.
ABOUT GLASS TUBE FUSES ON CERTIFIED
DEVICES
There are glass tube fuses on the circuit board's load outputs, these
have a tripping time of approx. 150 ms. In the event that a glass tube
fuse trips on ONE load output, the voltage on ALL load outputs drops
to 0 V for 150 ms.
The installer is responsible for ensuring that there is an energy buffer
of at least 150 ms in systems that the battery backup supplies power
to or accepts a power failure of 150 ms.

F3 T2A Reading protection 1 + (for P2: 1)
F4 T2.5A / T4A Mains fuse, the lower valute for units 5 A - 15 A and the higher value for 25 A units.
F5 T16A Load fuse 1+ (for P2: 2)
FUSE REPLACEMENT WARNING (A)
There is a risk of damage if the fuse is changed to a larger one than what the unit
is delivered with. The function of the fuse is to protect the connected load and cables
against damage and fire. It is not possible to change the fuse to a larger one to
increase the power output.
6.2. Connect the mains to the motherboard (PCB)
6.2.1. Connect mains
Pull wiring through the cable entry on the cabinet.
If possible, secure the mains cable with cable ties where possible.
Electrical network cabling shall be kept separate from other cabling to avoid EMC interference.
Figure 6. Connect the mains to the motherboard
Connect the mains cable to the terminal before it is put back on the motherboard. Secure F and N with
cable ties for electrical safety.

BOARD
Check that the marking on the circuit board matches the cable arrangement on the
terminal block.
6.3. Connect load
MAX CURRENT
Maximum current must not be exceeded. Maximum current is indicated on the CE-
marking on the unit.
If there are one or more connection cards (to increase the number of load outputs), load must be
connected there and not on the main board.
Table 7. Load connections
Circuit board number Explanation
P2: 1 Connection for load 1 +
P2: 2 Connection for load 1 -
P2: 3 Connection for load 2 -
P2: 4 Connection for load 2 +
CAUTION
Load may only be connected to the motherboard in 5 A and 10 A units. For other units,
load must be connected via power board or option board.
6.4. Connection of load 15 A - 25 A units
For units with a effect card, which is available to handle the higher currents (15 ampere and above), the
load must be connected on an optional board.
See documentation for option board for how to connect load.
WARNING
Load must not be connected to the motherboard if the device is a 15 A or 25 A, as it
will be destroyed during commissioning. Motherboards that are faulty due to incorrect
connections are not covered by warranty.
14

Figure 7. Effect card
The effect card increases the current for 15 A and 25 A units.
6.5. Load cards with blade fuses
The card replaces the load output on the motherboard.
The load card has a different type of fuse that is easier to change and at the same time the card
provides a easier connection of the load.

6.8. Configuration of communication via RS-485
Communication via RS-485 is connected to P2: 7- & P2: 8+.
The address is set binary on the switch.
ADDRESS configuration:
Table 10. S1 Dip switch
Dip switch Value
Dip switch 1= 1
Dip switch 2= 2
Dip switch 3= 4
Dip switch 4= 8
If all dip switches are set to OFF, the address is 0+0+0+0=0.
If dip-switch 1 and 3 are ON, the address is 1+0+4+0= 5.
If dip-switch 2 and 4 are ON, the address is 0+2+0+8=10.
For Sentrion only: addresses in Sentrion add +1. This means that 1 must always be added to the
configuration.
If all dip switches are set to OFF, the address is 0+0+0+0(+1*)=0 (1*).
If dip-switch 1 and 3 are ON, the address is 1+0+4+0(+1*)= 5(6*).
If dip-switch 2 and 4 are ON, the address is 0+2+0+8(+1*)=10(11*).

to set the alarm.
Table 13. Mains failure delay
Alarms for mains failure are given after: Dip 5 Dip 6
10 seconds OFF OFF
30 minutes OFF ON

6.9.3. Low battery level (dip 7)
Dip: 7 has the same function regardless of whether the unit is in mains or battery operation or whether
the tamper switch is held down.
Table 14. Low battery level
Alarm for low battery level is given Dip 7
22,8 V* ON
24 V OFF
*25% of battery capacity remains.
6.9.4. LED (dip 8)
LED/battery-test always lights up when the door is open.
Dip-switch 8=ON turns off the LED.
Dip-switch 8=OFF turns on the LED.
6.9.5. Battery test (dip 8)
To do a battery test, dip 8 needs to change position and five seconds need to pass before the test is
initiated.
• If dip 8 in original position is on OFF then switch dip 8 to: ON (wait 5 seconds) and then switch back
to OFF.
• If dip 8 in original position is on ON then switch dip 8 to: OFF (wait 5 seconds) and then switch back
to ON.
This activates the battery test after 3-8 seconds. The battery test lasts for about 6 seconds and then
the LED flashes yellow quickly. Aged battery alarms may be indicated while the battery test is being
performed.
Only reset dip 8 when the test is complete.
6.10. Reboot to confirm changes in address, battery and alarm set-
tings to parent system
After the dip-switch has been set for various parameters, the device's software needs to be restarted.
This is for the new settings to be stored and take effect.
Restarting the device software is done by jumpering J13 (PRO2)
IMPORTANT
Reboot must be done every time a change is made to the device.

6.11. Alarm card for PRO2
Relay card - description, connections and alarm outputs.
• All fault arm relays must be in the drawn state. Check that there is a gap between CO and NC. Put
the measuring instrument on continuity measurement and test closure. This should then indicate a
short circuit.
• All relay outputs are normally live and give an alarm in the event of no voltage.
