Symmetra LX Bypass Dry Contact Output

This question was originally posted by Federico on APC forums on 4/19/2010


I'm in hurry trying to determine if there is a way to know when the external bypass of a symmetra LX is used with a dry contact Output.

Online Manuals lack detailed information.

Is there a way to extract a dry contact from this bypass: SBP16KRMI4U

Why? The symmetra LX has a major problem when going in bypass mode (static or manual). All the current goes through L1 so I'm left with two options, turn off the extra load with a trip coil circuit to protect wires or cut the power to the UPS (not possible).
