4. INSTALLER'S INFORMATION NOTES
421 Positive battery is supplied at terminal 21 of terminal board TG3 when the rectffiir is in aquake mode of opam-
4.22 To shii the phase of the input voltage of the rectifier wfth respect to the AC line service to lower the cumulative
distortion on the AC line when two or more ractffffrs are operated in parallel, interchange any two input phases
at input line contactor K2. When more than two rectiriets are operated fn parallel. intarchanga any two AC input
phases at input line contactor K2 on alternate ractifiers.
4.23 During a Phase LossReducad Load Alarm condfft rectffer output voltage and currant are at a reduced level
and external alan contacts are actiitad to provided a closed loop dtwits between tarmfnak 26 and 27 and29
to 30 and open loop circuits between terminals 25 to 26 and 28 to 29.

An optional customer furnished 46 volt 10 ampere auxilff power supply can be cormacted to these two termi-
nals 1 (+) and 2 (-). Connecting a functtonfng power suppfy to these terminals will allow fhe rectifier to restart
tery may have &charg& too low to hefp restart the rectifier. Afso ff the recfffier system does not tnclude a bat-
tery the rectlfll will not automatIcally restart wllhouf external pomer.
connected to these terminals the rectifier will not restart automatfcalty after an extended AC input power failure
and a restart procedure wftl have to be performed.
