Fig. 4-22 Wiring system bus
RA1, RA2 Bus terminating resistors 120 Ω (included in the accessory kit)
• Connection via pluggable screw terminals (double terminals can be used).
• Only connect terminals of the same designation.
• Features of the system cable:
Total cable length up to 300 m 300 m to 1000 m
Cable type LIYCY2x2x0.5mm
2
twisted-pair with shielding
Pair 1: CAN-LOW (LO) and CAN-HIGH (HI)
Pair 2: 2*GND
CYPIMF2x2x0.5mm

• Connection of the bus terminating resistors:
– One resistor 120
Ω each on the first and last bus device.
– On the 93XX controller the resistor can be screwed directly under the terminals X4/HI and
X4/ LO.
