Disconnect the mains supply voltage before you work on the
devices inside the enclosure.
Installing the components
1. Mount the Access Modular Controller (AMC2) on the right-
hand side of the mounting rail.
2. Mount the power supply unit on the left-hand side of the
mounting rail.
3. If you are using rechargeable batteries, install the batteries
at the bottom of the enclosure and secure them with a
fixing bracket.

3.2 Connecting the cables
Notice!
See chapter Cable assembly, page 22 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 12) 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 13).
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 2).
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 (D)
1. Connect the grounding cable D to the cover grounding
point (Figure 1.1, position 1) and to the grounding point on
the cover of the enclosure.
2. Close the cover.
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.
Notice!
Change the lead batteries every 5 years.
