Fig.4 Control panel dimensions and fixing opening arrangement
The 230 V/50 Hz mains conductors must be fastened to the mains power supply terminals – Fig.2,
paying attention to careful conductor fixing that precludes accidental touching of bold conductor
endings. The control panel can be used only in the case of application of additional protection against
electric shocks, such as zeroing or protective grounding. Laboratory tests, checking the required by
the standards in force interference immunity, have been carried out with grounding application.
8 CONTROL PANEL SPECIAL APPLICATIONS
8.1 EXPLOSION ENDANGERED PREMISES PROTECTION
Installation of fire detectors and manual call points in zones where explosive mixtures of gases and
liquid vapours occur is possible in intrinsically safe detection circuits. Such circuits provide the [Ex I
b
IIC] safety category.
Intrinsically safe detection lines in the IGNIS 2000 system can be created in conventional lines with an
application of intrinsically safe separators. Detailed information concerning the device installation in
explosion endangered areas is available at the intrinsically safe element manufacturers.
