7.1 Information regarding electrical connections
INFORMATION! Always insert the mains cable at the bottom right;
insert all other electric cables (signal leads) through the top of the
control cabinet.
Route all the electrical supply cables into the system through the
strain relief screw connections.
Route the supply cables in the cable conduits provided there. Fol‐
lowing installation, tighten all threaded connectors. Tightly seal all
the threaded connectors not in use with the blanking plugs pro‐
vided.
n
The system is fully wired. You now need to connect the system
to the local single-phase mains power supply. Ensure that you
connect the live, neutral and protective earth conductors cor‐
rectly as per the wiring diagram.
The electrical installation of the system requires fixed wiring.
Do not use a standard power lead to connect the system to the
local power supply network. If the power supply connections
are done incorrectly, safety equipment, in particular the door
position switch, which disables the system when the door is
opened, may not work correctly.
n
The electrical supply equipment must be capable of being dis‐
connected by an Emergency Stop switch (emergency com‐
mand device). Install the Emergency Stop switch in an easily
accessible position in the vicinity of the entrance door to the
plant operating room.
1.
The ozone generation system together with the water treat‐
ment system feed pump must be locked by the pause input
on the control circuit board.
2.
The gas detector needed to operate the system must have
an isolated contact which must be electrically connected to
the terminals – see terminal wiring diagram in the Appendix.
This ensures that ozone generation is interrupted in the event
of the release of ozone gas.
3.
All other electrical connections must be wired according to
the wiring diagram in the Appendix.
