NOTE: The phase order in which the conductor terminal lugs are connected to
circuit breaker terminals X, Y, and Z will be determined during the Phase
Check Procedure.
10. Install the conductor terminal lugs to the circuit breaker terminals X, Y,
and Z as shown in
Figure 4-3
.
11. Torque the screws to 30-35 in.-lbs (3.4-4.0Nm).
12. Leave a service loop of extra cable in the electrical enclosure to prevent
strain on the electrical connections. Tighten the clamp on the cable
strain relief.
13. Insert and hold 1/2 of the conductor isolator block behind the wires at
the circuit breaker terminal block.
14. While holding conductor isolator block, slide the terminal block cover
(containing the other conductor isolator block) up so that the conductor
isolator blocks fit around the conductors and into the tray within the
terminal block cover as shown in
Figure 4-2
.
15. Reinstall the terminal block cover by rotating the screws 1/4 turn.
16. Reinstall the electrical panel cover by rotating the screws 1/4 turn.
17. Connect the power source end of the power cable according to the local
electrical codes.
18. Proceed with
Phase Check
.
High Voltage
High voltage electric shock could cause severe injury or
loss of life.
Phase Check
1. Make sure power is supplied to the High Capacity Helium
Compressor circuit as described in
2. Turn the High Capacity Helium Compressor circuit breakers CB1 and
CB2 to the ON position. If the High Capacity Helium Compressor
does not start and the
REVERSE PHASE
indicator is illuminated, refer
to step 3. If the High Capacity Helium Compressor starts, you have
completed the phase check procedure.
3. If the High Capacity Helium Compressor does not start and the phase
monitor indicator is illuminated, perform the following steps:
a. Turn the High Capacity Helium Compressor circuit breakers
CB1 and CB2 to the OFF position.
b. Disconnect the power cord from the power source.
