3.3 Cabinet Wire Routing All wiring should be installed in conformance with the applicable local, national, and international codes (for example, NEC/CEC). Figures 3.3 and 3.4 show the wire routing, grounding terminal, and power terminal strips of the cabinet. Control wiring enters the cabinet through the three holes on the left side and terminates at the control panel’s terminal block. Tighten the control wire connections from 7.1 to 8.9 in-lb. 3.

Step 3. Use a wrench to further tighten the connectors 1.5 to 2.5 turns. Do not hold the bulkhead fitting with a pipe wrench when tightening the connectors as the fitting may be damaged. Note that the bulkhead fitting has a built-in anti-rotation feature and will not turn as the connector is screwed in. ! ATTENTION: The cabinet’s bulkhead fittings may be damaged if they are held with a pipewrench. Do not hold the bulkhead fitting with a pipe wrench when tightening the connectors.

CHAPTER 4 Connecting Cabinet Power Wiring This chapter describes how to connect input and output power to the cabinet. 4.1 Cabinet Input Disconnect ! ATTENTION: The user is responsible for conforming with all applicable local, national, and international codes. Failure to observe this precaution could result in damage to, or destruction of, the equipment. An input disconnect circuit breaker is factory-installed in the cabinet.

4.3 Installing Input Power Wiring (12-Pulse Rectifier Cabinet) ! ATTENTION: The user is responsible for conforming with all applicable local, national, and international codes. Failure to observe this precaution could result in damage to, or destruction of, the equipment. Use the following steps to connect AC input power to the cabinet: Step 1. Remove the top panel of the cabinet. Important: Care must be taken to prevent debris from falling into the cabinet while performing this installation. Step 2.

CHAPTER 5 Cabinet Servicing This chapter describes how to remove the Liqui-Flo drive from the cabinet and provides a list of replacement parts. 5.1 Removing the Liqui-Flo Drive from the Cabinet Follow the procedure in section 5.1.1 if you are removing a Liqui-Flo drive from a 6-pulse rectifier cabinet. Follow the procedure in section 5.1.2 if you are removing a Liqui-Flo drive from a 12-pulse rectifier cabinet. 5.1.
Step 6. Disconnect the Flexibar conductors at the drive’s U, V, and W output terminals. a. Remove the two 3/8”-16-UNC-2B nuts from the clamp holding the Flexibar to the AC output busbar at output terminals U, V, and W. b. Remove the load plate and the clamps. c. Save this hardware for reassembly. Step 7. Remove the rigid buswork that connects the load side of the circuit breaker to the drive. a. Remove the 1/12”-13 bolts and washers from each of the drive’s AC input terminals (L1 through L6). b.
Step 16. Using the hoist, lift the drive slightly to take the load off of the cabinet’s panel studs. Pull the drive off of the studs and up through the wire entry and access panels until it is clear of the cabinet enclosure. Note that drive’s center of gravity is forward of the hoist, which will result in the top of the drive tilting forward during removal. Step 17. Move the drive to a horizontal pallet for servicing or shipment. The eyebolts and the chain between them do not need to be removed. Step 18.
b. Connect one end of a drain hose to the accumulator on the closed loop coolant system. Connect the other end of the hose to a drain. c. Connect a shop air line to the closed loop coolant system at the quick disconnect fitting. Pressurize the line to 60-90 psi for 1 to 2 minutes to flush all of the coolant out of the drive. d. Remove the basket from the Y-strainer and check for any contaminants. e.
Step 14. Using an overhead or portable hoist (minimum 1/2 ton rated capacity), attach a free-fall chain to the 1.5” hole in the support bar. Take up any vertical slack in the chain. Step 15. Vertically lift the support bar and the drive 3” to 4”. a. Rotate the support bar to the right side, towards you, and slip the support bar/drive assembly out of the cabinet. Step 16. Move the drive to a horizontal pallet for servicing or shipment. The support bar and screws do not need to be removed. Step 17.
