24VDC Power Cabling
In order to maintain compliance with EN standards, DC power must be delivered over a
shielded cable, with the shield connected to the return conductors at both ends of the
cable as shown in
Figure 2-6 . Conductors should be 1.5 mm 2 - 1.85 mm 2 (16 to 14 AWG) in
size. The maximum length for the 24VDC cable is 10 meters.

Daisy-Chaining Power
The SmartController is equipped with two DC power connectors. These connectors allow
the daisy-chaining of power from one controller to another or to a sDIO module. When
daisy-chaining power, the power supply circuit must be limited to the lesser of 8 Amps or
the ampacity of the cabling. This can be done with a circuit breaker or a fuse. The DC
power can be applied to either the XDC1 or XDC2 connector.
Grounding
The SmartController is equipped with a grounding point. See Figure 2-7 . Adept
recommends connecting a ground wire from the ground point on the controller to earth
ground and that all other interconnected Adept components share the same electrical
ground potential. The ground wire must meet all local regulations. Additional grounding
information for other Adept products are provided in the documentation for those
products.
NOTE: The maximum length for the ground wire for the SmartController
is 3 meters.
CAUTION: Use only one 24VDC power supply per circuit.
Failure to do this could result in damage to the equipment.
