3.2 Connecting the cables
Notice!
See chapter Cable assembly, page 21 for a list of UL
approved/listed cables and UL authorized suppliers.
Connecting the AMC2 power cable (A)
1. Connect the 7-pin plug A7 (Figure 4.1) to the power supply
connector (label: POWER) of the AMC2.
2. Attach connector A8 (Figure 4.1) to the power supply
connection labeled OK.
3. Attach connector A9 (Figure 4.1) to the power supply
connection DC.
4. Connect the grounding cable A6 (Figure 4.1) to the AMC2
grounding point.
Connecting the AC power cable (F)
1. Use the cables to connect the three-pin connector (Figure
1.1, position 11) to the AC connector (Figure 4.6, position
F4) of the power supply.
2. Connect the blue wire to the port marked with N (Figure
3.2, positions 2 and 4).
3. Connect the brown wire to the port marked with L (Figure
3.2, positions 1 and 3).

Mounting and connecting the power cable with LED indicator
(G)
Notice!
Use this cable (G) instead of cable F if you are installing a
system that is to be UL approved.
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,
marked with L1 (Figure 3.2).
6. Connect the single blue wire to the position 4, marked with N
(Figure 3.2).
7. Connect the other end from the blue wire to the position 2,
marked with N ( Figure 3.2).
Connecting the tamper contact (E)
1. Mount the micro switch with two screws M2 x 10 mm
(Figure 1.1, position 6) at the right side of the enclosure.
2. Connect the loose ends of the tamper contact cable to the
two-pin screw connector (marked with T) at the top of the
AMC2.
3. 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.
Connecting the cover grounding cable
1. Connect the mounted grounding cable (see position F of
Parts included, page 6 ) to the cover grounding point
(Figure 1.1, position 1) and to the grounding point on the
cover of the enclosure.
2. Make sure that the screws of the two earthing points are
sufficiently tightened.

3.3 Connections for supporting Universal
Power Supply
Precondition: Before switching to battery operation, disconnect
the AC power cable.
Notice!
Use 12V 7 (7,2)Ah lead batteries only.

4.1 UL requirements
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.
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).
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.
Notice!
If the system is to be UL294 compliant, make sure that all the
cables and the respective parts are UL listed or approved.
Notice!
All supplier examples given in chapter Cable assembly, page
21 are UL authorized.
