Wiring
CAUTION: Use care when removing the
knockout. Do not damage the circuit board.
If possible, use the top knockout position.
Do not use autotransformers. Use earth ground
isolating step-down Class 2 transformers.
Determine supply transformer rating by summing total
VA of all actuators used. The maximum rating for a
Class 2 step-down transformer is 100 VA.

• Wiring for SKB/C62U is shown in Figures 22
and 23.
• Wiring for SKB/C82…U is shown in Figures 24
through 26.
• The position output signal U will switch from 0
to 10 Vdc to 4 to 20 mA when a 4 to 20 mA
input signal is selected and used on the
terminal.
