    The same rule must also be observed with separate power lines: the lengths of the cables of the bypass line + output line must be the same between all the MASTER HE connected in parallel. Lack of compliance with this rule may cause a current imbalance between the UPSs when the load is powered through the bypass line.

    Maintenance The uninterruptible power supply is designed and produced to last a long time even in the most severe service conditions. It should be remembered however that this is electrical power equipment, which requires periodic controls. Moreover, some components have a limited lifespan and as such must be periodically checked and replaced should conditions so dictate: in particular the batteries, the fans and in some cases the electrolytic condensers.
