3 Connection of the Devices
Figure3.1: Connections in the Enclosure
Connect the readers and other peripheral devices as described
in the AMC Installation manuals and in the manuals of the
peripheral devices. Route the device cables through the knock-
outs in the top and right side wall of the housing, or through the
rear of the housing.
Notice!
Make sure that the mains adapter has the correct output
voltage (12V or 24V).
When installing the enclosure, make sure to provide an
appropriate disconnect device for the mains supply voltage.
Removing a fuse or simply pulling the plug is not an appropriate
means to disconnect the device!

Warning!
Risk of electric shock!
Disconnect the mains supply voltage before doing any work at
the devices inside the enclosure.
Notice!
All cables connected to the AMC modules and the power supply
are classified as Class 2 Conductors, with the exception of the
battery cable and the AC input cable. These two are non-power
limited circuits.
Notice!
For UL installations a minimum of ¼” (6.4 mm) spacing is to be
maintained 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 (see areas 3 and 4 in Fig.
3.1).
Mounting Components
1. Mount the AMC on the rail on the right (item 2 – Fig. 1.1)
and left aside the power supply.
2. If rechargeable batteries are used, put them on the bottom
of the housing and secure them using clip 7 (Fig. 1.1).
The components described below refer to Cable A (Figure 1.2):
Cable A - AMC Power Cable
1. Connect the 7-pin plug A1 to the AMC’s power supply
connector (labeled: POWER).
2. Attach connectors A3 to the PS-interface DC and A2 to the
interface labeled OK.
3. Connect the grounding cable A4 at the grounding point 3
(Fig. 1.1).

The components described below refer to Figure 1.1:
Cable 12 - AC Power Cable
Connect the 2-pin plug 13 on the interface AC of the power
supply.
Cable 5 – Tamper Cable
Connect the loose ends of the cover tamper switch to the 2-pin
screw connector on the top of the AMC marked with T. Position
the cable in the space between the housing and the mounting
rail.
Danger!
Risk of electric shock
Make sure that all wires to be connected have Zero potential!
Main AC supply X:
1. Connect the grounding cable to the housing at position 8 in
figure 1.1.
2. Connect the blue (neutral) wire to terminal N.
3. Connect the brown (phase) wire to terminal L1.
Notice!
Shorten the external supply wires so that the ground (yellow/
green) wire is at least 20 mm (0.8 in.) longer than the live (blue
and brown) wires. This ensures that the ground wire cannot be
accidentally disconnected before live wires.
Cable 1 – Cover grounding Cable
1. Connect cable 1 to the grounding point on the cover.
2. Close the cover.

4 Connections for Supporting UPS
Notice!
Before switching to battery operation disconnect the AC Power
Cable (Fig. 1.1 – item 13) from the power supply.
Notice!
Use only 12V 7Ah batteries.
Change lead batteries at least every 5 years
Notice!
In UL installations, if the fuse is blown, order cable No.
F.01U.328.004 with your regional spare part desk to replace the
entire battery cable.
Cable G - Battery temperature sensor cable
1. Attach connector G1 on the PS-interface labeled RTH.
2. Route the cable across the temperature sensor bracket 6 so
that the temperature sensor G2 hangs approximitely 5 cm
(2 in.) above the rechargeable batteries.

The 12 V mode can be configured using one or two rechargeable
batteries. For a one-battery installation, refer to the Figure 4.2
(left), and perform the following procedure:
1. Connect B1 to the power supply position labeled BAT.
2. Connect B2a (black) to the rechargeable battery’s –
terminal, and B2b (red) to the rechargeable battery’s +
terminal.
3. Stick the bracket (Fig. 1.2 – item J) on the back of the
housing next to the batteries.
4. Connectors B3a and B3b remain unused - fix them using
the bracket J.
For the two-battery installation, refer to the Figure 4.2 (right)
and perform the following procedure:
1. Connect B1 to the power supply position labeled BAT.
2. Connect B2a (black) to the rechargeable battery’s –
terminal, and B2b (red) to the rechargeable battery’s +
terminal.
3. Connect B3a (black) to the second rechargeable battery’s –
terminal, and B3b (red) to the second rechargeable
battery’s + terminal.
