- Page 5 Liebert MBSM or preparing the system for installation. Be constantly aware that the Liebert MBSM contains high voltages. Check for voltage with AC and DC voltmeters before making contact. Observe all safety precautions before working on or near the Liebert MBSM or the UPS system. WARNING Risk of electric shock.
- Page 6 WARNING Risk of electric shock. Can cause equipment damage, injury and death. The area around the Liebert MBSM must be kept free of puddles of water, excess moisture and debris. This equipment contains circuits that are energized with high voltage. Only test equipment designed for troubleshooting should be used.
- Page 7 EC Declaration of Conformity The Liebert MBSM is in conformity with the protection and safety objectives of the following European directives: • 2006/95/EC Directive of the council for adaptation of the legal regulations of the member states regarding electrical equipment for use within specific voltage limits (superseding the 73/23/EC and successive amendments).

Page 8: Introduction
This signal is a square wave generated by an incoming source reference or by an internal quartz oscillator. Each UPS connected to the Liebert MBSM is able to receive the frequency reference signal and, under particular conditions, to automatically phase lock the inverter to this reference. - Page 9 The Liebert MBSM has a simple, passive role in relation to the UPS. The UPS will decide on the source of synchronization on the following priority scale: • Highest Priority = Local Reserve Input • Medium Priority = Liebert MBSM Reference •...

(feedback signal to the Liebert MBSM locked to OK condition). The Liebert MBSM will select one of the two buses to generate the frequency reference. The reference bus selection is random if both of them are inside preset limits. A manual selector on the Liebert MBSM permits a priority on one specific bus. -
Page 18: Liebert Mbsm Activation On Bus A
2.8.1 Liebert MBSM Activation on Bus A Both the power buses are inside limits and the Liebert MBSM is set on the Bus A; this means that the frequency reference generated by the Liebert MBSM is actually phase referred to the Bus A. If... -
Page 19: Generator Operation
If after a while, the faulty power Bus A is powered back by the generator, the Liebert MBSM will sense that this new source is not synchronous (normally that is) with the power Bus B and will keep the system A forced on frequency reference sync. This automatic behavior is possible only if the local priority switch is in automatic position. -
Page 20: Both Power Bus Failure
Should both power buses be replaced by generator after a fault sequence of both the power buses, the Liebert MBSM will do the following: • If local priority switch is on auto, the Liebert MBSM will select one of the two generators as a source for system synchronization. •... -
