Both closed: Bus termination for the RS485 interface active (1500Ω between
RS485P and RS485N, 3900Ω from RS485P to +5V supply, 390Ω
from RS485N to earth)
Note: Application: When using the optional operator panel OP1S at the basic device
interface SST1 (X100 or X300), DIP switches S1 and S2 must be closed.
0Ω resistances as earth-frame (M) connection
M is connected to earth when the unit is supplied. Remove these resistances only to
avoid faults due to earth loops, i.e. if the electronics frame is connected in some other
way to earth (e.g. through signal leads or the frame terminal of the power supply unit).
If option modules are used, a further earth-frame (M) connection may have to be
removed. (please refer to the description of these modules).
