Comet installation and user manual: E-6761200XT/FA Merlin Gerin by MGE UPS SYSTEMS 10.5
separate Mains 2 transformer (AC bypass input)
This option can be used to connect the "static bypass" 3 to a second AC input
circuit, if the two AC input come from different sources or if they are fitted with
separate protective devices.
This requires installation of the optional "separate Mains 2 galvanic isolation
transformer".
The cables requiring connection are indicated as bold lines.
For information on cable cross-sections, see the "appendices": "selection of cable
cross-sections" (the connection cable between Comet and the option is supplied).

This option comprises a high-frequency filter which limits the disturbances
transmitted to the AC input power supply and guarantees compatibility with the
standards in force. This guarantee is no longer provided if the transformer is used
on its own (without a filter).
Note: for a 5 kVA Comet S11 or S31, the shielding of the Mains 2 cable must be
secured to the stud provided on the connection cover panel (see appendices).
