In the event of a UPS with 15-20 kVA single-phase output, it is
essential to connect the auxiliary mains to the relative dedicat-
ed terminal board. If there is no separate mains for the bypass, it
is advisable to obtain one from the primary mains in one of the
two ways set out below:
• with distribution external to the UPS (figure .5-6).
• with a bridge connection (figure .5-7).
