8.1 Information relating to electrical connections
CAUTION!
Warning of incorrect operation and defects
– The mains cable enters at the bottom right; all
other electric cables (signal leads) enter
through the top of the control cabinet.
All the electrical supply cables to the plant must pass through the
strain relief screw connections into the inside of the system.
Lay the supply cables in the cable ducts provided there. Following
installation, tighten all the threaded connectors. Tightly seal all the
threaded connectors not in use with the blanking plugs provided.
CAUTION!
– The system is fully wired. It only has to be con‐
nected to the local single-phase mains power
supply. Ensure that the live, neutral and protec‐
tive earth conductors are connected correctly
as per the wiring diagram.
The electrical installation of the system must
use fixed wiring. It must not be connected via a
standard power lead to the local power supply
network! If the connections to the power supply
are incorrect, safety equipment, in particular
the door safety switch, which disables the
system when the door is opened, may not work
correctly.
– The electrical supply equipment must be
capable of being disconnected by an emer‐
gency cut-off switch (emergency command
device). Install this in an easily accessible posi‐
tion in the vicinity of the entrance door to the
operating room.
1.
The ozone generation system together with the feed pump of
the water treatment system must be locked via the Pause
input on the control circuit board -
2.
The gas detector needed to operate the system must have a
potentially isolated contact which must be electrically con‐
nected to the terminals – see 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.
8.2 Electrical inputs and outputs of the system
The system has the following inputs and outputs, which are avail‐
able to the user to control and manage the generation of ozone -
see the terminal connection diagram in the appendix:
