Important Notes

Please read before installing.

1. Caution: To avoid overheating and possible damage to other equipment, do not use to control

receptacles or transformer-supplied appliances.

2. Install in accordance with all national and local electrical codes.

3. The Electronic Switch (MA/MSC-S8AM) requires a neutral wire for operation. If no

neutral wire is present, contact a licensed electrician for installation. No neutral wire is

necessary for the installation of the Accessory Switch (MA/MSC-AS).

4. When no “grounding means” exist in wallbox, the 2011 National Electrical CodeR (NECR) allows

a control to be installed as a replacement if 1) a nonmetallic, noncombustible faceplate is used

with nonmetallic attachment screws or 2) the circuit is protected by a ground fault circuit inter-

rupter (GFCI). When installing a control according to these methods, cap or remove green wire

before screwing control into wallbox.

5. Do not paint front or back of Electronic Switch (MA/MSC-S8AM) or Accessory Switch (MA/

MSC-AS).

6. The Maestro® Electronic Switch (MA/MSC-S8AM) is not compatible with standard 3-way or

4-way switches. Use only with MaestroR Accessory Switches (MA/MSC-AS).

7. In any 3-way/4-way circuit use only one Electronic Switch (MA/MSC-S8AM) with up to 9

Accessory Switches (MA/MSC-AS).

8. Do not use where total load is greater than rating indicated in the Derating Chart below.

9. Do not use where total lighting load is less than 5 W.

10. Operate between 32 °F (0 °C) and 104 °F (40 °C).

11. It is normal for the Electronic Switch (MA/MSC-S8AM) to feel warm to the touch during opera-

tion.

12. Recommended minimum wallbox depth is 2.5 in (64 mm).

13. Maximum wire length between the Electronic Switch (MA/MSC-S8AM) and the furthest

Accessory Switch (MA/MSC-AS) is 250 ft (76 m).

14. When controlling a combined fan and light load, the total load may not exceed 3 A.

15. Clean switches with a soft damp cloth only. Do not use any chemical cleaners

16. Electronic Switch (MA/MSC-S8AM) must be installed on the load side of the circuit.

(2.5 or 1.5 mm²) ground wire with

one 18 AWG (0.75 mm²) switch

ground wire.

Twist wire con-

nector tight.

Push-in Terminals: Insert wires fully.

NOTE: Push-in terminals are for use with

14 AWG (1.5 mm²) solid copper wire only.

DO NOT use stranded or twisted wire.

Screw Terminals: Tighten securely.

Screw terminals are for use with 12 or

14 AWG (2.5 or 1.5 mm²) solid copper wire

only. DO NOT use stranded or twisted wire.

Trim or strip wallbox wires to the length indicated by the strip gauge on

the back of the switch

Multigang Installations

When combining controls in the same wallbox, remove all inner side sections prior to wiring (see

diagram). Using pliers, bend side sections up and down until they break off. Repeat for each side

section to be removed. Refer to the Derating Chart below for maximum Electronic Switch capac-

ity. Please note that the Electronic Switch is not derated for fan loads, but when controlling a

combined fan and light load, the total load may not exceed 3 A.

Please call the Lutron Technical Support Center at +1.800.523.9466 for an up-to-date listing.

* Note: The maximum lamp wattage is determined by the efficiency of the transformer, with

70–85% as typical. For actual transformer efficiency, contact either the fixture or transformer

manufacturer. The total VA rating of the transformer(s) shall not exceed the VA rating of the

switch.

For Two-Location Control wiring, follow Figures A and B. One location will be replaced with

an Electronic Switch and the other with an Accessory Switch.

Note: Electronic switch must be installed on the load side of multi-location wiring.

For Three-Location Control (or more) wiring, follow Figures A, B and C. One location will

be replaced with an Electronic Switch and the others with Accessory Switches. Only one

Electronic Switch can be used with up to 9 Accessory Switches.

Wiring the Accessory Switch on Line side:

•Connectthegreen ground wire on the Accessory

Switch to the bare copper or green ground wire
