3.2 Power Supply
3.2.23 How to connect the power supply (MAC800/1200)
The power supply for the control circuitry is connected through the expansion module
at the terminals called P+ and P- or directly at the internal power supply connector.
The power circuitry must be applied according to the illustration below.
Terminal descriptions:
L1 115/230VAC input (phase). (The voltage range is set by solder jumper)
N 115/230VAC input (neutral). (The voltage range is set by solder jumper)
See Using 115V supply voltage (MAC800/1200), page 103.
PE Earth must be used with the DC-bus and the PD terminals.
PD Power dump output - see also Connecting an external power dump resistor, page
104.
BO Bus output (nom. 325VDC).
CM Common. Ground for the internal DC-bus.
Important notes:
- If 115VAC is used as supply voltage the MAC800 must be set up for this. See Using
115V supply voltage (MAC800/1200), page 103.
- Shielded cables is recommended.
3.2.24 MAC800/1200 Grounding
Make sure that the machine part on which the MAC800/1200 is mounted is properly
grounded to the main part (body) of the machine in order to avoid major ground/earth
current to flow through the motor and cause interference to other signal groups such as
interface cables.

Main power, internal bus voltage and power
dump are accessible through these spring
contacts placed under the top lid.
Mains power must be 115 or 230VAC.
Control power (+18-30VDC) must
be connected to the P+ and P- terminal
at the expansion module.
See the actual module used, for details
of connection.
