FACTORY WIRING
FIELD WIRING
TERMINAL BOARD
SYMBOL LEGEND
USE 18 AWG WIRE MINIMUM. TO MINIMIZE INTERFERENCE
PROBLEMS:
USE SHIELDED WIRE ON ALL ANALOG INPUTS AND
OUPUTS. DO NOT RUN 0-10 VOLT DC SIGNAL WIRING
IN THE SAME CONDUIT AS LINE VOLTAGE WIRING OR
WITH WIRING THAT SWITCHES HIGHLY INDUCTIVE
LOADS SUCH AS CONTACTOR AND RELAY COILS.
GROUND ONE END OF THE DRAIN (SHIELD) WIRE.
WHEN 0-10 VOLT DC SIGNAL WIRING MUST CROSS
CLOSE TO CABLE OR NONMETALLIC CONDUIT
CONTAINING LINE VOLTAGE WIRING OR WIRING THAT
SWITCHES HIGHLY INDUCTIVE LOADS, IT MUST CROSS
PERPENDICULAR (90 DEGREES) TO IT.
KEEP THE 0-10 VOLT DC SIGNAL WIRING AS SHORT AS
POSSIBLE.
USE SHIELDED WIRE FOR ALL
ANOLOG OUTPUTS
WIRE ALL SHIELD WIRES TO CLOSEST TB-A
“GND” TERMINAL AT THE CONTROL PANEL

Adjustable Power Supply
0843P-0524
Failure to properly configure the 0843P-
0524 adjustable power supply before
applying power may result in damage to the
power supply or connected equipment.
The “J1” & “J2” jumpers should be
configured for “HALF” wave mode.
Before applying power for the first me
remove the wires from VDC + & - and
connect a volt meter, then apply power.
LED1 should light.
Adjust the “P1” adjustment screw by
turning the screw to 24VDC.
If the desired voltage is less then the
current voltage shown by the volt meter
turn the “P1” adjustment screw clockwise.
If it is more then the current voltage turn
counter clockwise
