3.2 Power Supply
3.2.31 How to connect power supply (only MAC1500, MAC3000 &
MAC4500)
The low voltage (24VDC) 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 Main power (400-480VAC nom.) must be applied according to
the illustration below.
Terminal descriptions:
L1 400-480VAC input (U phase) WARNING: Please be aware that high voltage can be
present also when the terminal is unconnected!
L2 400-480VAC input (V phase) WARNING: Please be aware that high voltage can be
present also when the terminal is unconnected.
L3 400-480VAC input (W phase) WARNING: Please be aware that high voltage can be
present also when the terminal is unconnected!
PE Earth Make sure to connect this terminal to a proper
ground in order to avoid electrical shock.
............
Note: Please use shielded cables only. The shield must be connected to the metal con-
nector housing which is also internally connected to the earth terminal.
3.2.32 Sizing the external fuse (Prefuse).
To met UL requirements, the prefuse must be a class RK5 such as the type FRN-R-8
(8Amp.) for MAC1500 and FRN-R-15 (15Amp.) for MAC3000 and FRN-R-25 (25Amp)
for MAC4500 from manufacturer: Cooper Bussmann INC.
3.2.33 MAC1500, MAC3000 & MAC4500 Grounding
Make sure that the machine part on which the MAC1500, MAC3000 or MAC4500 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.
