A visual inspection of the plant should be carried out in order to detect obvious
faults. Make sure that the mechanical installation of components is correct and
that electrical connections are firmly in place (e.g. in the DC link). Make sure
that all electrical connections have been made correctly before switching on the
power supply. Check the 230 VAC and 24 VDC supply voltages as well as the
shields and earthing connections.
The relevant wiring blocks on the MSTT, HHU, PLC I/O components should be
wired up and checked for start-up.
Reference material: /BH/ Device Manual, Operating Components
The MSTT, HHU and PCU components may be switched on in any order if they
are physically present.
Switch on the power supply on all components and on the mains supply mo-
dule. No enabling signals need be present initially on the mains supply module.
The LEDs on the NE module must not indicate any faults in the power supply.
Danger
Before switching on, make sure that the protective cover and connector X181
are attached to the power supply unit.
