Installation walk-through for 045488
Lutron document 045488 gives five steps, in the document's order, after the fixings it lists.
The clearance, the check and the warning under a step are the document's own.
Fixings
- Power cord supplied, or an approved cord with an IEC C13 connector
- Cord: 18 AWG (1.0 mm²) 3-conductor, 300 V, 140 °F (60 °C)
- Cord length 6 ft (1.83 m) to 10 ft (3 m)
- Fasteners suited to the mounting surface, through the tabs (optional)
- One twisted, shielded pair of 22 AWG (0.5 mm²), communication link
- Power and common conductors sized from the run length table
- Conductor sizes: 12 AWG (4.0 mm²), 16 AWG (1.5 mm²) or 18 AWG (1.0 mm²)
Mount the power supply (optional)
Fix the supply through its mounting tabs with fasteners that suit the surface, tightened by hand.
Lutron recommends a location that stays accessible. The supply must not interfere with the window treatment or any other moving device.
Check: Supply reachable later and clear of the shade's travel
Warning: Hand tighten only; no power tool on the fasteners
Prepare the conductors
Strip 1/4 in (6 mm) of insulation from each conductor. Tighten every terminal screw firmly to 5 in-lb (0.5 N·m) as each wire is landed.
Clearance: Strip 1/4 in (6 mm); torque 5 in-lb (0.5 N·m)
Check: No insulation inside the terminal block
Connect the drive or the power draw units
Land the power and common wires on the matching 35 V and COM terminals. In a wired control installation, land the communication wires on the matching MUX and MUX terminals.
A wireless control installation leaves those terminals empty.
Clearance: 35 V and COM run, one drive: 250 ft (75 m) on 12 AWG (4.0 mm²), 100 ft (30 m) on 16 AWG (1.5 mm²). On 18 AWG (1.0 mm²), 50 ft (15 m).
Check: One drive and at most one PDU, or up to 8 PDUs with no shade
Warning: +35 V is never connected between devices that supply power draw units
Connect further supplies on the link (optional)
Several supplies, each with its own devices, may be daisy-chained along the wired communication link. Land the incoming link wires on one side of the pass-through and the outgoing wires on the other.
Clearance: All QS link wiring in the system not over 2000 ft (610 m)
Check: Only the communication link joins the supplies
Warning: No +35 V conductor runs from one supply to the next
Connect the AC cord
Use the cord supplied, or any approved cord that suits the installation site and meets the IEC C13 cord requirements. Plug the cord into the supply first, then into a standard receptacle.
Clearance: Cord 6 ft (1.83 m) minimum, 10 ft (3 m) maximum
Check: Cord is 18 AWG (1.0 mm²) 3-conductor, rated 300 V and 140 °F (60 °C)
