Safety instructions

This instruction manual contains important safety information.

Read this instruction manual.

Keep this instruction manual in a safe place. Always include this instruction manual when passing the system on to third parties.

Heed all warnings.

Follow all instructions.

WARNING: To reduce the risk of fire or electric shock, do not expose the device and the mains unit to rain or moisture.

Disconnect the mains connector from the wall socket to completely discon- nect the device from the mains during lightning storms or when unused for long periods of time.

Use only the supplied mains unit.

Ensure that the mains unit is:

always readily operable and easily accessible,

properly plugged into the wall socket,

only operated within the permissible temperature range (see “Specifi- cations” on page 11)

not covered or exposed to direct sunlight for longer periods of time in order to prevent heat accumulation.

Use of the MO 2000 CU central unit

The MO 2000 CU central unit has been designed for use with the MO 2000 H optical microphone.

Rack mounting

When installing the device in a closed or multi-rack assembly, please consider that, during operation, the ambient temperature within the rack may signi- ficantly rise above room temperature. However, the ambient temperature within the rack must not exceed the temperature limit specified in the speci- fications.

When installing the device in a rack, take good care not to affect the ventila- tion required for safe operation or provide additional ventilation.

Make sure the mechanical loading of the rack is even to avoid a hazardous condition such as a severely unbalanced rack.

When installing the device in a closed or multi-rack assembly, please note that intrinsically harmless leakage currents of the individual devices may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.
