Pull cables

1. Check cable type, size and maximum distances

2. Pull cables for all inputs and outputs

3. Check device power requirements

Cable distance

Cable type	Cable format*	Single HBUS device – data only	Single HBUS device – data and power	Multiple HBUS devices – data only	Multiple HBUS devices – data and power
CAT 5e or better**	4 twisted pair Each 2 x 0.2 mm2 (24 AWG)	500 m (1640 ft)	50 m (165 ft)	500 m (1640 ft)	50 m (165 ft)
SEC472	4 x 0.2 mm2 Not twisted pairs (24 AWG)	400 m (1310 ft)	50 m (165 ft)	–	–
SEC4142	4 x 0.4 mm2 Not twisted pairs (21 AWG)	400 m (1310 ft)	100 m (330 ft)	–	–

* The matching of wire sizes to equivalent wire gauges are only approximate. ** Recommended cable types for optimal HBUS RS485 performance.

Shielded cable may reduce the obtainable cable length. Shielded cable should be grounded at the Controller end only.
