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.
