PME-MP85
A0897−3.4 en HBM
The shield of each transducer cable should be connected at the PME end by
as short a line as possible (t5 cm) and a blade connector (4.8 mm;
“Faston”).
The lines to connect the power supply and the digital control inputs and
outputs only need to be shielded if the cable length exceeds 30 m or if the
lines are installed outside closed buildings.
When connecting the lines (clip on and pull off clamps) and when replacing
the MMC, measures must be taken against electrostatic discharge to prevent
damage to the electronics.
The MP85/MP85DP module should be operated at a separated extra−low
voltage (SELV) (supply voltage 18 − 30 V DC) that usually supplies one or
more consumers within a control panel.
If the device is operated on a direct voltage network

, additional precautions
must be taken to discharge excess voltages.
Conversions and modifications
The MP85/MP85DP module must not be modified from the design or safety
engineering point of view except with our express agreement. Any
modification shall exclude all liability on our part for any resulting damage.
In particular, any repair or soldering work on motherboards is prohibited.
When exchanging complete modules, use only original parts from HBM.

Distribution system for electrical power with greater spatial expansion (e.g. via several control panels) that
may possibly even supply consumers with high nominal (rated) currents.
