Type 0(A)7-3704-2***/**** (gas)
To put the APEX (SILAS) pressurized cabinet into operation, proceed as follows:
-
Make sure that the operating pressure of the purging gas for the
pressurized encapsulation is set at the pressure reducer station to the
pressure specified on the type plate.
-
Close and lock the main door of the APEX (SILAS) pressurized cabinet.
An overpressure is then built up in the pressurized enclosure due to the
inflowing purging gas.
As soon as the inner pressure exceeds the set minimum limit, the purging time
starts to count down. After expiry of the purging time, the internally protected
assemblies and components are switched on as follows:

APEX pressurized cabinet, type “pxb“: the internal fitted components are
automatically switched on.

APEX (SILAS) pressurized cabinet, type “pyb“ and “pzc“: the internal
components are either switched on automatically or manually by the
operator.
The APEX (SILAS) pressurized cabinet is ready for operation from this point in
time.

Dust the enclosure
-
Make sure that the operating pressure of the purging gas for the
pressurized encapsulation is set at the pressure reducer station to the
pressure specified on the type plate.
-
Close and lock the main door of the APEX (SILAS) pressurized cabinet.
An overpressure is then built up in the pressurized enclosure due to the
inflowing purging gas.
As soon as the inner pressure exceeds the set minimum limit, the APEX (SILAS)
pressurized cabinet is in a safe state. The internally protected assemblies and
components are switched on as follows:

APEX pressurized cabinet, type “pxb“: the internal fitted components are
automatically switched on.

APEX (SILAS) pressurized cabinet, type “pyb“ and “pzc“: the internal
components are either switched on automatically or manually by the
