NOTE: 1) The wire diagram shows the wiring set up for a high voltage (460VAC) three phase system. To wire the system as a low voltage (230VAC or 208VAC) three phase system, see the transformer diagram in Detail F and motor wiring in Details D & E. 2) Fork Terminals are used to connect to the transformer. The green contacts are grounding terminal blocks and must connect to bare, unpainted DIN rail. 3) The transformer uses IP 2X finger safe protection guards. The electrical box has a keyed cam latch and lift off hinge to secure the door. The transformer is a class 2 transformer and the disconnect / emergency shut off is rated as a motor breaking switch. 4) Primary branch circuit protection consisting of an inverse time fixed trip circuit breaker rated at 30kA IC trip must be provided by the end user. A WS-5 must be attached to a breaker properly sized for the equipment. A single weld station unit must not be attached to a breaker greater than 250% of the FLA of the motor according to NEC Code. The breaker should be rated at 125% of the unit FLA rounded up to the next standard breaker size.

8) The light on the Start / Stop double push button must illuminate when the motor contactor is activated. The push button is wired so that the normally closed contact (NC) is 'STOP' and the normally open contact (NO) is 'START' and activates the motor. 9) See Details D and E for motor wiring. Clean Air America has standardized on "Wye" or "Star" voltage wiring method. Wiring connections in the motor’s pecker head must be made using the screw terminals of the distribution block. The distribution block must be screwed to the inside of the pecker head. 10) All wires and air tubing leaving the electrical box should be bound together and prevented from laying lose on the cabinet floor. The wires must be routed out of the electrical box and attached to the floor of the cabinet using the wire routing tracks. The cables should then turn up the first valve and route under the reservoir to the second valve. The motor cable is attached to the conduit and then through the 3/4" strain relief. Wires should be tight, but not stressed. 12) Once attached, the door must open fully at least 90 degrees with out interference. The door is also removable for eased maintenance. 13) Main power for the lights is drawn from the electrical box to a main junction box in the valve compartment. The lights for the main unit are connected directly to the terminal strip inside this junction box. A similar junction box is located on the top of secondary booths. Power for the lights in the secondary booth is run from the junction boxes back though the conduit and wire tracks to the main light distribution box and connected to the terminal strip. Electrical connection for the secondary booth to the main booth is done using the quick connects shown in Detail C. These connectors are located inside the wire track beneath the intake. 14) WIKA and Dwyer sensors are wired and operate identically. If a Kavlico sensor is used, a voltage regulator is used to drop the 24VDC down to 5VDC. If a Dwyer sensor is used see Detail J; no voltage regulator is needed. If Dwyer sensor is used, an additional mounting hole must be drilled. See Detail M for wiring of the Kavlico sensor. 15) The following labels must be applied: (2) “Ground Symbol” labels applied to the box next to the grounding terminal blocks. (1) “Danger High Voltage, Disconnect power before servicing” label applied to the outside of the electrical door next to the disconnect. (1) “Laminated Electrical Diagram” applied to the inside of the electrical door. (1) “NEMA 12” label applied to the inside of the electrical box. 16) When adding an economizer, a hole must be drilled in the bottom of the electrical box for each economizer lead. Next, 18-2 SOOW cable is run as shown in Detail G. There is no polarity on the economizer. 17) When adding a Remote Start / Stop button, a hole must be drilled in the bottom of the electrical box. Next, 16-3 SOOW cable is run as shown in Details H and L. The jumper from 20 to 34 must be removed. 18) SOOW cable and THHN wires are rated for 600V. All 480V wires are isolated from other wires by 30mm. Wires for the pressure sensor are isolated from all wires carrying voltage higher than 24VDC by at least 30mm; additionally, the sensor circuit is protected using a 3A breaker.
