AMC Power Supply – Diagnostic LED‘s When AC is ≥85V~ green LED AC is ON and relay AC is closed When DC is ≥12V or ≥24V the green LED DC in ON and the relay DC is closed When battery voltage is ≥11V (12V operation) or ≥22V (24V operation) the green LED BAT is ON and the relay BAT is closed For battery operation When input voltage is <85V~ ≥24V the power supply changes to mode “Battery operation” and yellow LED BOP goes ON The button POWER OFF is enable in battery operation mode only. Push it to switch off the output voltage A restart is only possible when AC mains voltage is already switched on 5 4 3 2 1

AMC Power Supply – Diagnostic relays When AC mains is ≥85V~ green LED AC is ON and relay AC is closed When DC is ≥12V or ≥24V the green LED DC in ON and the relay DC is closed When battery voltage is ≥11V (12V operation) or ≥22V (24V operation) the green LED BAT is ON and the relay BAT is closed Relay common 4 1 3 2

AMC Power Supply – Voltage output selection The power supply can operate in 12V- or 24V-mode. To change between the two modes, disconnect the input voltage and set the switch as shown in the figure.

Connecting the Bosch power supply Warning: Never shortcut pin 1 and pin 6 respectively and pin 3 and pin 7 to share the power supply for internal electronics and peripherals like this was arranged with the AMC version 1! With AMC 2 this is now arranged with jumper settings.

AMC Grounding and shielding (Host interface) The main grounding point at the AMC2 will be connected with pin 2 of the power supply connector. It is good practice to shield all wires carrying low level signals. The AMC enables you to set up a central ground or shielding point, simply by setting a couple of jumpers. Set these jumpers only if ground or shield is not connected otherwise. Setting jumper JP1 connects the AMC’s internal ground to the RS-485 host interface ground. Jumper JP2 manages the signal ground (PAG). Setting jumper JP1: If the ground conductor and the shield are are not connected and no partyline exists, JP1 is set as under A2 a partyline exists, JP1 is set at the first device only as under A2 Setting jumper JP2: If the ground conductor and the shield are not connected and no partyline exists, JP2 is set as under A3 a partyline exists and PAG is connected, JP2 is set at the first device only as under A3 a partyline exists and PAG is not connected, JP2 is set at all devices as under A3 If the AMC is set to RS-232 mode, JP1 must be set as under A2.

AMC Grounding and shielding (extension interface) Jumper B connects the AMC’s internal ground to the RS485 ground of the slave interface. Jumper B shall only be set (B2) if the AMC powers all other peripheral devices which are directly connected to the AMC!
