3.3.2 Cutting ring screw connections
w
In the case of cutting ring screw connections, incorrect installation of the
pressure lines can lead to a destruction of the replacement plate due to the
acting forces.
w
The cutting ring screw connection may not be mounted to the device in one
work step.
1. Mount the cutting ring using a pre-assembly connecting piece.
2. Always use a conventional assembly paste
(1)
to avoid cold welding of the
stainless steel parts.
3. Carry out the final assembly work on the device with just one counter-hold.
Mount the cutting ring screw connection with a quarter or half-turn of the
union nut.

3.4 Electrical connections
• By authorized and qualified specialized personnel only.
• When connecting the unit, the national and international electro-technical
regulations must be observed.
• Disconnect the system from the mains, before electrically connecting the
device.
• Install the consumer-adapted fuses.
• Do not connect the connector if strained.
3.4.1 Operation in areas at risk of explosion
WARNING
Do not connect the connector if strained
Sparks can be created, the plug is mounted under tension or replaced.
• If operated in explosive areas, the electrical data of the unit and the valid
local regulations and guidelines for the installation and operation of elec-
trical systems in explosive areas must be observed (e.g. DIN EN 60079).
• If units are used in potentially explosive areas, the personnel must receive
additional training or briefings or have a permit to work on explosion-protec-
ted units in potentially explosive systems.
• A CE-conform mains adapter with a slow 200 mA fuse only may be used in
the power supply circuit.
NOTICE! The outer ground connection must always be connected to the
protective potential equalisation or a similar local potential equalisation.
The ground terminal is suitable for connecting fine-wire conductors up to 4 mm
2
or single-wire conductors up to 6 mm
2
.
