10.3 Connection to the Network
There are the following different versions:
• Encoder with link adapter – connection via cable fitting
(*1)
• Encoder with bus link adapter – connection via screw-in system M12
(*1)
• Encoder without bus link adapter – connection directly via screw-in system M14

Not all versions are available for each encoder type
10.3.1 Installation Notes re: Voltage Supply
The operating voltage is generally supplied via a separate line and is not designed as a line
structure. If, for the voltage supply, the same cabling arrangement as used by the bus is imple-
mented, the following limitation applies:
Max. current flow across the plugs or terminal block in the bus link adapter is lim-
ited to 2 A
.
Max. number of encoders [series connection] is 10.
10.3.2 ATM 60 with Bus Link Adapter – Cable Fitting
ATM 60 with bus link adapter – connection via 3 cable fittings. The electrical wiring is via the in-
ternal terminal block (X1).
