INSTALLATION INSTRUCTIONS

WARNING:

 

TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL

CODES AND REGULATIONS.

WARNING:

 

IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT A

QUALIFIED ELECTRICIAN.

WARNING:

 

TO REDUCE THE RISK OF OVERHEATING AND POSSIBLE DAMAGE TO THIS DEVICE AND

OTHER EQUIPMENT, USE ONLY WITH THE APPROPRIATE ADVANCE MARK X™ 120V ELECTRONIC
DIMMING BALLASTS FOR CONTROLLING THE SPECIFIC FLUORESCENT LAMPS.

OTHER CAUTIONS:

1.

BOTH LIGHTING FIXTURE AND DIMMER MUST BE 

GROUNDED

.

2.

DISCONNECT POWER WHEN SERVICING OR CHANGING LAMPS.

3.

USE THIS DEVICE ONLY WITH COPPER OR COPPER CLAD WIRE. WITH ALUMINUM WIRE USE ONLY
DEVICES MARKED CO/ALR OR CU/AL.

MULTI-GANG INSTALLATION:

When ganging dimmers, the side sections of the mounting strap must be removed. Use pliers to carefully bend
side sections back and forth until they break off 

(refer to Figure 1)

. The side sections dissipate heat, so removing

them requires a derating of the dimmer's capacity 

(refer to chart)

.

MAXIMUM BULB WATTAGE:

Advance Mark X™ dimmers are rated in Volt-Amps (VA). The maximum bulb wattage is determined by the efficiency
of the Advance Mark X™ ballast. 

Table 1 

shows the maximum number of ballasts that can be connected to a

single dimmer for different Advance Mark X™ ballasts. Also note the table shows maximum ballasts for multi-
gang installations.

NOTE:

 For multiple ballasts on one dimmer, use only the same model ballast.

TO INSTALL:

1.

WARNING:

 

TO AVOID FIRE, SHOCK, OR DEATH; 

TURN OFF POWER

 AT CIRCUIT BREAKER OR FUSE

AND TEST THAT POWER IS OFF BEFORE WIRING!

2.

Remove existing wallplate and switch or dimmer, if applicable.

3.

Remove 3/4" (1.9 cm) of insulation from each circuit conductor. Make sure that ends of conductors are straight.

4.

Connect lead wires per appropriate WIRING DIAGRAM as follows: Twist strands of each lead tightly and,
with circuit conductors, push firmly into appropriate wire connector 

(see chart for  allowable wire

connector and number of conductor combinations)

. Screw connectors on clockwise making sure that no

bare conductor shows below the wire connectors. Secure each connector with electrical tape.

5.

Carefully position all wires to provide room in outlet box for dimmer. Mount dimmer into box with mounting
screws supplied.

6.

Restore power at circuit breaker or fuse. Turn the dimmer ON by pressing the upper half of the rocker. The
GREEN LED will turn OFF to indicate power to the dimmer (when the dimmer is OFF, the LED is ON).

NOTE:

 This model incorporates a trim adjustment which will allow the installer to precisely set the low end of the

dimming range to suit each installation. This adjustment is preset at the factory and should require no further
adjustments for most installations. If adjustment is required proceed as follows, otherwise continue with step 9:

7.

The brightness adjustment is located on the side of the dimmer 

(refer to Figure 1)

. Using a small, insulated

screwdriver, depress the brightness adjustment switch. To increase the minimum brightness, press the upper
half of the rocker.
To decrease the minimum brightness, press the lower half of the rocker.

8.

Release the rocker. Release adjustment switch and minimum brightness is set. Check for
proper operation by tapping the lower half of the rocker so the lights turn OFF, then
tapping the upper half of the rocker so the lights turn ON.
The lights will turn ON to the new minimum brightness set. If operation is not satisfactory,
repeat step 7.

9.

Attach Decora

®

 wallplate (not included). 

INSTALLATION IS COMPLETE.

NOTE:

 On the lower left corner of the switch frame, there is an air-gap switch. When

servicing a controlled fixture, pull lever out (OFF position). This will cut the power to the
fixture. After servicing is complete, push the lever in (ON position) to restore power. The lever
must be pushed in all the way (ON position) for normal operation.
