3.2 Power Supply
3.2.8 How to connect power supply (only MAC400)
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 115VAC input (phase) WARNING: Please be aware that high voltage is pres-
ent also when terminal is unconnected!
L2 230VAC input (phase) WARNING: Please be aware that high voltage is pres-
ent also when terminal is unconnected!
N115/230VAC input (neutral).
PE Earth must be used with the DC-bus and the PD terminals.
PD Power dump out - see also Connecting an external power dump resistor, page 104.
BO Bus output (nom. 325VDC).
CM Common. Ground for the internal DC-bus.
............
Note: Please use screened cables only. The screen must be connected to the metal con-
nector housing which is also internally connected to the earth terminal.
3.2.9 MAC400 Grounding
Make sure that the machine part on which the MAC400 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.

Control power (+18-32VDC) must
be connected to the P+ and P- terminal
at the expansion module.
See the actual module used, for details
of connection.
Main power, internal bus voltage and power
dump are accessible through these connectors.
Mains power must be 115 or 230VAC.
