Unpacking and Installation
MNC-0300-001 13 of 20 Revision L
Three Phase Units
Phase orientation must be verified on initial installation. If the
phase orientation is not correct the amount of air flow will be
greatly reduced. Three phase units have a pressure switch that
senses the TWT air flow. If the phase orientation is incorrect the
HPA will shut down indicating a TWT Temperature fault. Refer
to the appendix titled Specifications for nominal line voltage and
prime power connections. If repeated TWT Temperature faults
occur during initial turn on you will need to reverse a phase pair.
Generally the AC Prime Power receptacle is located on the rear
of the amplifier.
Figure 5 through Figure 8 show diagrams of three phase
connections.
Table 2 through Table 5 delineate the pinouts for the three
phase connections.
