Illuminator to Power Supply
Connection (2-Wire)
The Illuminator is equipped with a 1.22m (48in), 3-
wire pendant cord. The RED lead is the positive
DC voltage leg. The BLACK lead is the common
DC voltage leg. The WHITE lead is not used.
Wiring must comply with all local codes.
Two jumper clips on the 1040-3060PSA terminal
strip (Figure 6) are required for 2-wire installations.
One jumper clip connects terS and +V
together. The second jumper clip connects
terminals –S and –V together.
These jumper clips remain in place for 2-wire
installations for both 120Vac and 230Vac
operation.
•
Connect the RED Illuminator lead to terminal 7
(+V) on the terminal strip.
•
Connect the BLACK Illuminator lead terminal 6
(–V) on the terminal strip.
•
Secure the unused WHITE Illuminator lead with
insulating tape or a wire nut.
Four-Wire Connections
The 1040-3060PSA Power Supply uses "remote
sensing" to maintain a constant voltage at the
Illuminator. A 4-wire configuration between the
power supply and the Illuminator maintains the
correct load voltage over a long wire run.
Jumper Clip Removal
The 4-wire method does not use jumper clips on
the 1040-3060PSA terminal strip, except for initial
voltage adjustments (see Adjusting the 1040-
3060PSA Output Voltage, page 6).

The Illuminator is equipped with a 1.22m (48in), 3-
wire pendant cord. The RED lead is the positive
DC voltage leg. The BLACK lead is the common
DC voltage leg. The WHITE lead is not used.
Wiring must comply with all local codes.
Note:
Test all power supply outputs for 13.5
±0.1Vdc before connecting to the Illuminator. For
information on setting the 1040-3060PSA Power
Supply output voltage, see page 6.
•
Switch off all 120Vac or 230Vac source voltage.
•
Connect a "sense" lead from terminal 8 (+S) on
the terminal strip to the RED Illuminator wire.
•
Connect a power lead from terminal 7 (+V) on
the terminal strip to the RED Illuminator wire.
•
Connect a power lead from terminal 6 (–V) on
the terminal strip to the BLACK Illuminator wire.
•
Connect a "sense" lead from terminal 5 (–S) on
the terminal strip to the BLACK Illuminator wire.
