2.1. General
2. Installation
Installation and commissioning of GDMS-OMD14 is conducted or supervised by
personnel from MSS AG or its authorized representatives.
A training for the on-site operation personnel and/or the commissioning data on a
CD are available on request.
The wiring diagram and schematic given here are guidelines only. The actual wiring
will be adapted to the existing alarm and monitoring system on-site.
The GDMS-OMD14 has to be installed to the engine wall in the manner specified,
that the appropriate component (electronic system) sits in the non explosive engine
room outside the crank case and the intrinsically safe component (Sensor) sits
inside the crank case with its Ex-category 2G requirements.
For non intrinsically safe electric circuits (current supply and RS 485 interface) Um
of DC 30 V is compulsory.
For the connection to the 230V power supply the current supply of the GDMS-
OMD14, inclusive the devices, connected to the RS485 interface have to:
• either be supplied by an electric power supply unit with safe galvanic isolation
• or the supply current circuit and the current circuits of the RS 485 interfaces have
to be carried by an engineered safety barrier. Special instructions/requirements,
constituted in the certificates of these engineered safety barriers, have to be
necessarily carried out.
For further installations instructions refer to the Installation Manual.
