The main grounding point at the AMC2 4W will be connected 

with pin 2 of the power supply connector - see Figure 7.6.

It is good practice to shield all wires carrying low level signals. 

The AMC2 4W enables you to set up a central ground or shield-

ing point, simply by setting a couple of jumpers. Set these 

jumpers only if ground or shield is not connected otherwise.

For short distances below 25m (75 feet) use AWG18 conduc-

tors. For higher distances install an additional power supply 

close to the AMC.

Please, calculate the voltage drop by checking the conductor 

specifications for characteristic resistance values. The voltage 

drop shall not exceed 2V.

Example:

Length = 100m/328 ft

The cables used in the AMC2 4W access control system are not 

prone to electrical interference. However, you should avoid 

routing cables close to heavy load switching cables and equip-

ment. If this is unavoidable, cross the cable at right angles every 

1 to 2 m (3 to 6 ft) to reduce interference.

Risk of damaging equipment!

When using multiple AMC2 4W devices, set the ground main 

jumper only once to assure a central point star connection.
