Black-out System Installation
SPLICE DRIVE SHAFT
1. Position all four drive pipe runs in the CLOSED position. In this position, the open bay--or the bay without the drive
pipes--will be the bay at the end wall to which the 113650 wire tensioners are attached. Verify that 2" of drive pipe
extends into the open bay. See diagrams below.
2. Once in place, the four rack arms should be sitting
in the rack drives in the same position across the
power rafter. If not, adjust as needed so that all four
rack arms are identically sitting in the four rack drives.
Temporarily secure drive pipes in place.
3. Return to the drive shaft and motor couplers. Field
drill through-holes and splice all coupler connections
