8.2 Option
8.2.1 Bypass Load Sharing Inductor
Install the bypass load sharing inductors for the parallel system comprised of two or more UPS modules, to
ensure the bypass output load sharing for the parallel system. The bypass load sharing inductor is used to
compensate the impedance differentia between SCR and cable.
Each UPS cabinet has three bypass load sharing inductors, with no extra clearance occupied. The load sharing
rate is generally 10% of the system rated current with the difference of external cable configuration. Try to
make the cable length be the same from bypass to each UPS and from UPS module output to parallel system
connection point.
Preparing installation tools
Make sure that all installation tools are present, including a cross head screwdriver, a pair of diagonal cutting
pliers, a sleeve spanner and an adjustable spanner.
