Connecting the voltage supply/RS 485 at the MA 8-01
Figure 8.2: MA 8-01 - Connection assignment PWR IN HOST/RS485
Attention!
Protection class IP 67 is achieved only if the connectors and caps are screwed into place!
Notice!
For connection of the voltage supply and interface, we recommend our ready-made cables.
For further information, see chapter 11.3 on page 87.
Attention!
Before connecting the device, be sure that the supply voltage agrees with the specified val-
ue.
Connection of the device and cleaning must only be carried out by a qualified electrician.
The power supply unit for the generation of the supply voltage for the BPS 8 and the respec-
tive connector unit must have a secure electrical insulation through double insulation and
safety transformers according to EN 60742 (corresponds to IEC 60742).
Be sure that the functional earth is connected correctly. Error-free operation is only guaran-
teed if the device is connected to functional earth.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.
To then further isolate the error, proceed as described in chapter 10 on page 85.
