Fig. 2 — Transformer Location and Wiring

11. Attach the black wire labeled no. 1 to the L1 connection. Attach the red wire labeled no. 1 to the L2 connection. Attach the black wire labeled no. 2 to either brass screw on the GFI outlet. Attach the white wire labeled no. 2 to either silver screw on the GFI outlet. (See Fig. 3 for GFI-CO wiring.) 12. Attach one end of the 30-in. long ground wire to the green ground screw on the GFI outlet. Secure the other end of the ground wire from the conduit to the TRAN1 ground terminal. 13. Ensure that all electrical connections are tight and restore power to the unit. 14. Test the GFI-CO by pressing its “Test” button and checking for power at the outlet. If the accessory is incorrectly wired, the GFI-CO may not trip and power may be present at the outlet. If power is present, disconnect all power to the unit, correct the accessory wiring, reconnect the unit power and retest the outlet. 15. When the GFI-CO trips and no power is present at the outlet, restore the circuit by pressing the “Reset” button on the GFI-CO. 16. Remove tags from disconnects and close the control box door. NOTE: After the GFI-CO is installed, periodically test the ground fault feature as described in preceding Steps 14 and 15.

6. Primary and secondary fuses are supplied with each package. A single secondary fuse (FNM-6) should be installed. Install the primary fuses as shown below according to the main power supply of the chiller in the fuse holder clips: Use fuses FNQ-R-21/2 for 460 V and 575 V units Use fuses FNQ-R-31/2 for 208/230 V and 230 V units NOTE: Rejection type fuses are installed one way only. Make sure they are secure in the fuse holder clips. 7. Using the screws provided, install the cover on the transformer box. 8. Route the other end of the conduit away from fan and refrigerant piping to back of control box. Remove knockout in control box below Main Base Board (MBB) and above row of condenser fan, heater and pump contactors. 9. Attach conduit to back of control box. 10. Install power connector from kit (3RV19155A) on top of a condenser fan or pump manual starter that has only 1 bus bar connection. Do NOT install or disturb the wiring to the cooler/pump heater circuit breaker (MS-CHC-L3) connection. If the MS-CHC circuit breaker is the only available point of connection, crimp the no. 8 spade terminals provided on the no. 1 labeled black and red wires.
