 Have the start-up with the bypass key switch approved by the
operations manager or his representative. Approval may only be

the risk of explosion have been taken (fire permit).

is deactivated when the key switch is activated must be attached in
the direct area of the key switch.
A bypass key switch can be connected separately to the APEX / SILAS control
unit.

be attached in the immediate vicinity of the bypass key switch.
The position of the bypass key switch is queried by the control electronics in an
