3.2.15 How to connect the power supply
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.
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.
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 (only MAC800), page 67.
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 68.
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 (only MAC800), page 67.
- Screened cables is recommended.
3.2.16 MAC800 Grounding
Make sure that the machine part on which the MAC800 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.
