Anleitung Zusammenfassung
Proceed with the following steps: Step 1: Verify that the line and load cables comply with applicable electrical codes. Step 2: Verify that the transfer switch rated current and voltage (see identification plate on the door of the transfer switch) agree with system current and voltage. Step 3: After the transfer switch is mounted, provide the conduit or cable openings as required. Ensure that no metal filings contaminate the transfer switch components. Step 4: Test all power cables before connecting them to the unit to insure that the conductors or the cable insulation have not been damaged while being pulled into position. Step 5: Carefully strip the insulation from the power cables. Avoid nicking or ringing of the conductor strands. Prepare the stripped conductor termination end by cleaning it with a wire brush. If aluminum conductors are used, apply an appropriate joint compound to the clean conductor surface area. Refer to Figure 13 for the approximate locations of the power connections. Power cables are to be connected to solderless screw type lugs located on the transfer switch switching devices. Refer to the separate Customer Wiring Diagrams supplied with the transfer switch equipment for power termination. Verify that the lugs supplied will accommodate the power cables being used. Also verify that the cables comply with local electrical codes. Standard transfer switch equipment, as supplied from the factory, will accommodate the wire sizes shown in Table 5. Table 5. Wire Size for Available Power Cable Connections.

Step 6: Tighten the cable lugs to the torque identified on the label affixed to the door. Step 7: Make the necessary connections of any options using the wiring diagrams supplied with the unit. Step 8: Connect the engine start wires to the logic connector J5-1 & J5-2 on the ATC-600/ATC-800 Controller.

FAILURE TO DO SO MAY CAUSE SERIOUS INJURY OR DEATH. • Remove the transformer pack cover by loosening the 4 screws located at each corner of the transformer pack assembly. • The transformers are factory set on the 600 volt tap. (See illustration above for location of various taps and voltages) • Detach the spade connector from the 600 volt tap and place on the tap that is suitable for your application. . CAUTION BE SURE THAT THE CORRECT VOLTAGE IS SELECTED TO MATCH THE SYSTEM VOLTAGE. AN IMPROPER SELECTION AND/OR CONNECTION COULD RESULT IN EQUIPMENT DAMAGE. • After changing the taps on both transformers, replace the transformer pack cover and tighten all four screws. 4.7 Mounting the Switching Device in the Drawout Mechanism In structures equipped for drawout circuit breakers, a bolted-in cassette with movable extension rails supports the circuit breaker (Figure 22). The extension rails must first be pulled all the way out. Once the rails are fully extended, the circuit breaker can be carefully placed on the extension rails. Figure 22. One Side of Drawout Circuit Breaker Properly Seated on Extension Rails. IB01602011E For more information visit: Instructional Booklet Page 20 Effective: March 2007 Fixed and Drawout Magnum Transfer Switches CAUTION IT IS IMPORTANT TO TAKE GREAT CARE WHEN PLACING A DRAWOUT CIRCUIT BREAKER ON ITS EXTENSION RAILS. IF THE CIRCUIT BREAKER IS NOT PROPERLY SEATED ON THE EXTENSION RAILS, IT COULD FALL FROM THE RAILS CAUSING EQUIPMENT DAMAGE AND/OR BODILY INJURY. Carefully lower the circuit breaker down onto the extension rails. Be certain that the circuit breaker’s four molded drawout rail supports are fully seated in the extension rail cutouts on both sides (Figure 22). Do not remove the lifting yoke from the circuit breaker until it is properly seated on the rails. Once the circuit breaker is on the extension rails and the lifting yoke is removed, pro...
