HBM MP85A Operating Manual page 8

8
When connecting cables (fitting and extracting terminals) and when changing
the MMC/SD Card, measures must be taken to prevent electrostatic
discharge which could damage the electronics.
The MP85A process controller must be operated with a separated extra-low
voltage (18 ... 30 V DC supply voltage), which usually supplies one or more
consumers within a control cabinet.
Should the device be operated on a DC voltage network
tions must be taken to discharge excess voltages.
Conversions and modifications
The MP85A process controller must not be modified from the design or safety
engineering point of view except with our express agreement. Any modifica-
tion shall exclude all liability on our part for any damage resulting therefrom.
In particular, any repair or soldering work on motherboards is prohibited.
When exchanging complete modules, use only original parts from HBM.
The device is delivered from the factory with a fixed hardware and software
configuration. Changes can only be made within the possibilities documented
in the manuals.
