Connecting open-
collector outputs
All the system outputs, except for the relay output on the control panel motherboard,
are open-collector outputs.
•
OC1 and OC2 are open-collector outputs that sink maximum currents in accordance
with the
Table 2: Control panels - electrical and mechanical features
.
•
All the terminals configurable as outputs are open-collector outputs that sink a
maximum current of 150mA.
The wiring diagram below illustrates a series of typical connections which activate the
load of a Normally Open output when it closes to GND (
).

AUXREL32
If you intend installing this board, work carefully through the following steps.
1. Disconnect all sources of power to the control panel (Mains 230V a.c and battery).
2. Insert the plastic supports into their respective locations (
Table 4: Control panels
- description of parts, Z
) on the back of the metal enclosure.
3. Position the board holes on the supports and push the board towards the back of
the enclosure until it locks into position.
4. Insert the cable [A] into the connector [B].
5. Connect the two free wires of the cable [A] to terminals 14 (OC1) and 15 (OC2)
on the control panel motherboard. Ensure that OC1 and OC2 on the control panel
are appropriately connected (
Table 31: AUXREL32 - description of parts, C
).
6. Connect the wire [C] to the connector [D] and to the 2 free pins [E] of the con-
nector on the switching power-supply, as shown in the figure.
