3.2 Connecting the cables
Connecting the AMC2 power cable (F)
1. Connect the 7-pin plug to the AMC2 connector labeled
POWER.
2. Connect the 4-pin plug to the power supply connector
labeled OK.
3. Connect the 2-pin plug to the power supply connector
labeled DC.
4. Connect the grounding cable to the AMC2 grounding point.
Mounting and connecting the power cable with LED indicator
(I)
1. Pass the cable end through the front of the LED bracket
hole (Figure 1, position 12).
2. Carefully pull the cable through the back of the LED
bracket.
3. Make sure that the LED reaches and fits the LED bracket
hole.
4. Connect the single brown wire to position 3, marked with L
(Figure 3.2).
5. Connect the other end from the brown wire to position 1
(Figure 3.2).
6. Connect the single blue wire to the position 4, marked with N
(Figure 3.2).

Connecting the tamper contact (H)
1. Connect the loose ends of the tamper contact cable to the
two-pin screw connector (marked with T) at the top of the
AMC2.
2. Position the cable in the space between the housing and
the mounting rail.
Danger!
Risk of electric shock
Make sure that all wires have zero potential.
Connecting the main AC supply (X)
1. Connect the ground cable to the main grounding point
(Figure 1.1, position 8).
2. Connect the neutral wire to terminal N (Figure 3.2).
3. Connect the phase wire to terminal L1 (Figure 3.2).
4. Shorten the external supply wires so that the ground wire
is a minimum of 20 mm longer than the live wires.
– This will prevent the ground wire from being
accidentally disconnected.

4.1 UL requirements
i
Notice!
All cables connected to the AMC2 modules and the power
supply are classified as Class 2 conductors. The battery cable
and the AC input cable are non-power limited circuits.
i
Notice!
Maintain a minimum of 6.4 mm spacing between all class 2 or 3
conductors and all electric, light, power, Class 1 conductors,
non-Class 2 or 3 signaling conductors, or medium-power
network-powered broadband communications-circuit
conductors (Figure 3.1, position 1 and 2).
i
Notice!
When the fuse (5A) of cable B (power supply battery) is blown,
replace it with a UL listed fuse and reseal the fuse holder with a
heat shrink tube.
