4 DATA-A1* (-)
5 DATA-A1 (+)
14 DATA-A2* (-)
13 DATA-A2 (+)
3 Surge Protection
In terms of voltage, DATA is negative with respect to DATA*.
NOTE: Surge protection must be grounded to be effective.
NOTE: Ground each segment of the cabling at only one point to prevent ground loops, which can affect system
performance. Verify the actuator is properly grounded.
Limitorque defines an effective local earth ground as the M3 taps on the housing next to the terminal block. See figure
3.21.
NOTE: Safety ground may not be disturbed.
NOTE: Shielding is not sufficient to prevent induction of stray voltages onto signal leads from the power lines.
A network wiring diagram for a loop is shown in Figure 3.20.
