Adept EX SmartContoller - Manual (Page 22)

Chapter 2: Installation
NOTE: The power requirements for the user-supplied power supply will vary depending on the
configuration of the Adept SmartController EX motion controller and connected devices. A mini-
mum configuration of the controller, front panel, and pendant will require 2 A at 24 VDC. How-
ever, a 24 V, 5 A power supply is recommended to allow for additional current draw from
connected devices, such as external IEEE 1394 devices and digital I/O loads.
24 VDC Power Cabling
In order to maintain compliance with many standards, DC power must be delivered over a
shielded cable, with the shield connected to the frame ground at both ends of the cable, as
shown in the following figure. Conductors should be 1.5 mm

- 1.85 mm
2
(16 to 14 AWG) in
size. The maximum length for the 24 VDC cable is 10 meters.

Daisy-Chaining Power
The Adept SmartController EX motion controller is equipped with two DC power connectors.
These connectors allow the daisy-chaining of power from one controller to another or to an
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.
CAUTION: Use only one 24 VDC power supply per circuit. Failure to do
this could result in damage to the equipment.
CAUTION: The SmartVision EX vision controller has a higher current
demand and should be wired independently. Do not daisy-chain its
power from a Adept SmartController EX motion controller.
