Access Modular Controller 2

Closing the Case
Before aligning the covers, unplug any pluggable screw connectors. Insert the hooks on the
lower edge of the front cover into the lugs on lower edge of the plastic back cover [1]. Please
ensure that the BOSCH logo is not upside-down. The upper edge of the front cover now aligns
with the two-point snap-in closures on the upper edge of the back cover [2], and may thus be
clicked gently into place.
Hence the closing process is the reverse of the opening process.

Notice!
Risk of damage to equipment
If excessive force is required to close the front cover then it is probably incorrectly hooked
into the back cover. In such cases the display 'Dialog' button in the front cover will be
misaligned and will not function correctly.

Cabling
Notice!
Risk of malfunction
The cables used in the AMC2-4R4 access control system are not prone to electrical
interference. However, you should avoid routing cables close to heavy load switching cables
and equipment. If this is unavoidable, cross the cable at right angles every 1 to 2 m (3 to 6 ft)
to reduce interference.
4.5.1
Conductor data for power to AMC2
With the calculation below you can find out which cable type must be used. If you connect the
power supply and the AMC-device with the delivered cable set from the enclosure the
calculation is not necessary.
For distances below 25 m (75 ft) use AWG18 conductors (1mm²). For longer distances, install
an additional power supply close to the AMC2 controller.
