Mac Victor® Power Network (MVPN) Installation Instructions (Retrofits) 1. Determine which “critical circuit breakers” feed power to the remote receptacles and/or hard wired loads that are required to be tied into the power isolation and battery backup of the MVPN. This will typically be the POS network receptacles and related equipment, office computer, telephone system, security system, etc. 2. Remove the panelboard covers for the “critical circuit breakers”.
(Retrofit Installations - cont.) 14. Plug the POWERVAR UPM into the receptacle located on the right hand side exterior of the MVPN.

NUISANCE TRIPPING OF INPUT CIRCUIT BREAKER Some reports from field installations indicate that the 15 or 20 amp, single pole circuit breaker feeding main power to the Mac Victor® Power Network (MVPN) will sometimes trip off upon startup of the POWERVAR UPM. In all cases, factory testing has indicated that this problem is not associated with defects in the POWERVAR UPM.
