SAFETY INSTRUCTIONS
SET-2000 level switch must not be installed in explosive atmosphere.
Sensors connected to it may be installed in explosive atmosphere
zone 0, 1 or 2.
In case of installations in explosive atmospheres the national
requirements and relevant standards as IEC/EN 60079-25 and/or
IEC/EN 60079-14 must be taken into account.
If electrostatic discharges can cause hazards in the operating
environment, the device must be connected into equipotential ground
according to requirements with regards to explosive atmospheres.
Equipotential ground is made by connecting all conductive parts into
same potential e.g. at the cable junction box. Equipotential ground
must be earthed.
The device does not include a mains switch. A two pole mains switch,
which isolates both lines (L1, N), must be installed in the main power
supply lines in the vicinity of the unit. This switch facilitates
maintenance and service operations and it has to be marked to identify
the unit.
When executing service, inspection and repair in explosive
atmosphere, the rules in standards IEC/EN 60079-17 and IEC/EN
60079-19 about instructions of Ex-devices must be obeyed.
