1. Installation, Operation and Maintenance Instructions for safe use.

1.1 Safety rules.
OPTIMA-EX[GD] are designed as Group II Category 2 equipment and is suitable for use for fixed
installation in areas with explosion hazard designated Zone 1/21 and Zone 2/22. These operating
instructions must be kept in safe place for later consultation. Use OPTIMA-EX[GD] only for their
intended duty in the undamaged and clean condition, and only where the resistance of the material to
the surroundings is assured. No modifications are allowed to the OPTIMA-EX[GD] that are not expressly
mentioned in this instruction manual. When installing the OPTIMA-EX[GD] the clearance and creepage
distance shall be duly considered as topic 5.3 table 5.
The OPTIMA-EX[GD] are available in materials GRP with the following rated current 16A, 32A, 63A, 125A.
The plug series OPTIMA-EX[GD] have to be used only with SCAME socket series ADVANCE-GRP[GD], Ex
db eb IIC / Ex tb IIIC , with separated certification. The ADVANCE-GRP[GD] socket switch-handle move a
mechanical interlock mechanism that avoid to separate the plug contacts from the plug outlet when the
contacts are energized. The plug series OPTIMA-EX[GD] can be to pull-out only when the handle is in position
0 (zero).
