Control System and Shade Wiring Details
The power supply connections
1
–
10
are powered by two separate power feeds which are isolated from each other—
1
,
3
,
5
,
7
, and
9
are powered separately from
2
,
4
,
6
,
8
, and
10
. If the continuous load rating is exceeded on either
feed, the power LEDs for that feed scroll down to indicate that the level of current can only be sustained for
2 minutes on 2 minutes off limited duty cycles. The power draw should be lowered if continuous use is expected. If
this situation occurs, rearrange the loads between the two power feeds to evenly distribute the power draw.
Maximum Wire Runs
The cable length between the motor and power supply is limited by voltage drop along the cable. The following
limits should be observed for reliable performance.
NOTE
: Wiring must be home run from the power supply to each shade motor.
Maximum total length of Cresnet cable run on each hub segment is 3000 ft (~915 m). Observe the following
maximum lengths for Cresnet cable between the power supply and shade:
•
Cresnet-P (Plenum Rated, 2x #18 Power, 2x #22 Twisted Data) 130 ft (~40 m)
•
Cresnet-NP (2x #18 Power, 2x #22 Twisted Data) 130 ft (~40 m)
•
Cresnet-HP-NP (2x #12 Power, 2x #22 Twisted Data) 500 ft (~153 m)
