INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off and the D-48-T unit connector is disconnected.
1. LAMPS OPERATED
The D-48-T can be used with most 2´-5´ lamps. If you have any questions regarding specific lamps, contact
Customer Service.
2. MOUNTING THE D-48-T
Remove the ballast channel cover. Mount the D-48-T in the ballast channel at least
1
/
2
″
away from the A.C. ballast(s).
When the D-48-T is remote mounted, the remote distance can not exceed
1
/
2
of the distance from ballast to lamp
specified by the A.C. ballast manufacturer. For example, if the A.C. ballast manufacturer recommends no more
than 25
′
remote distance, then the D-48-T should not exceed 12
1
/
2
′
.
Under no circumstances should
the D-48-T exceed a distance of 50
′
from the lamp.
3. WIRING
Refer to the wiring diagrams on the back page for the appropriate wiring of lamp(s) and ballast. Install in accordance
with the National Electrical Code and local regulations. For additional wiring diagrams consult Customer Service.
4. WIRING THE D-48-T
A. The D-48-T and A.C. ballast
must be on the same branch circuit.
B. The D-48-T requires an
unswitched A.C. power source of either 120 or 277 volts. Select the proper voltage
lead and cap the unused lead.
C. When the D-48-T is used with a switched fixture, the A.C. input to the D-48-T must be connected ahead of the
fixture switch. Refer to
Illustration 1 for switched and unswitched fixture wiring diagrams.
