Nortech Systems RS-232/TERM User Manual

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 

. 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.

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.

The SmartController is equipped with a grounding point. See 

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.

Use only one 24VDC power supply per circuit. 

Failure to do this could result in damage to the equipment.
