DC Input / Frame
Solid/Stranded wire; 12-24 awg (2.5-0.2mm). Strip length – 0.28” (7mm).
Torque rating: 4.5 – 7 lb-in (0.50 – 0.78 N-m).
DC- is internally connected to I/O V-, but is isolated from CAN V-.
A Class 2 power supply must be used.

3.1 - CAN Communications
CAN
Solid/Stranded wire; 12-24
awg (2.5-0.2mm). Strip
length – 0.28” (7mm).
Locking spring-clamp, two-
terminators per conductor.
Torque Rating: 4.5 lb-in
(0.50 N-m). V+ pin is not
internally connected, the
SHLD pin is connected to
Earth ground via a 1 M
ȍ
resistor and 10 nF capacitor.
