Wiring
Tools Required
Flat-blade screwdriver if terminal block is specified
Wire strippers
DISCONNECT ALL SUPPLY CIRCUITS BEFORE WIRING UNIT. WIRE IN ACCORDANCE WITH
NATIONAL AND LOCAL ELECTRICAL CODES. MAXIMUM RECOMMENDED WIRE SIZE IS 14 AWG.
THE RECOMMENDED TIGHTENING TORQUE FOR FIELD WIRING TERMINALS IS 6.5 IN/LBS.
ELECTRICAL RATINGS STATED IN LITERATURE AND ON NAMEPLATES MUST NOT BE EXCEEDED.
OVERLOAD ON A SWITCH CAN CAUSE FAILURE.
ALTHOUGH THE ONE SERIES INCORPORATES REVERSE POLARITY AND SURGE PROTECTION
ON THE POWER SUPPLY INPUT, IT IS HIGHLY RECOMMENDED THAT POLARITY AND VOLTAGE
LEVELS BE CONFIRMED PRIOR TO POWERING THE UNIT. IF SWITCHING OF THE OUTPUT ON START-UP
WILL HAVE ADVERSE AFFECTS ON THE SYSTEM, ENSURE THAT THE OUTPUT(S) ARE NOT CONNECTED
UNTIL THE PRODUCT HAS BEEN CONFIGURED APPROPRIATELY.
NOTE: If unexpected changes in the output will have an adverse affect on your system, it may be
best to configure the product off-line by applying temporary power to the device and programming
the mode, set point and deadband values. The inputs and outputs of the One Series product are
protected against reverse polarity and over voltage. However, correct wiring is essential to ensure
proper operation of the switch. Optional configurations may change the terminal designation,
location, wire color or size. Be certain to choose the proper wiring diagram for the product being
installed. See Diagrams 4 to 14 for wiring/terminal designations.
Ground Connections for Products Beginning with D1D
Connect ground wire to the Ground Screw in the upper left hand corner of the AC Power
Supply enclosure (see Diagram 3 - 115 VAC Power Supply Configuration).
Power Supply Connections (Models D1A, D1B, & D1C only)
The One Series is powered using an 18-30 VDC power source.
The power supply circuit common is shared internally with:
n
the IAW switched output (all models)
n
the 100 mA open drain switch output (models D1A & D1B only)
n
the optional 4-20 mA signal (all models)
Connect the positive (+) lead to the Red, 20 AWG wire (Model A) or
the terminal marked V+ (Models B & C).
Connect the negative (-) lead to the Black, 20 AWG wire (Model A) or the terminal marked circuit
common (Models B & C). See Diagram 4.
