HUB-SDM8
4. Installation and Wiring
A U-bolt is used to mount the HUB-SDM8 to a 1.25 inch NPT pipe.
The spring-loaded guillotines are opened with a small flat blade (2.5 x 50 mm)
screwdriver (p/n 8125). Orient the screwdriver blade so that the blade edge is
perpendicular to the orange separators. Gently insert the small flat blade
screwdriver into the square slot located next to the circular wire port until it
bottoms out. For the cluster of four wire ports located on the left hand side of
the HUB-SDM8, the guillotine release slot is located to the right of the wire
port. For the wire ports on the right hand side of the HUB-SDM8, the
guillotine release slot is located to the left of the wire port. Once the
screwdriver has been completely inserted and has bottomed out, firmly press
the screwdriver down until the guillotine snaps open. Insert and hold the wire
as the screwdriver is removed.
4.1 Wiring SDM Devices and Power Wires for Daisy-Chain
Before connecting the cable to the terminals, strip the wire insulation back to
expose 1/4 inch of bare wire. Feed the cable through the bulkhead fitting.
Neatly separate the wires, and connect them, using the technique described in
section 4 above. The figures below show how two SDM devices (CSAT3 and
LI-7500) and their power wires are connected within a daisy-chain network.
