options (cont')

full galvanic isolation transformer (standard Comet equipment)

This option is required to achieve a downstream neutral system different from the upstream neutral system. The transformer, installed in a cubicle of the same design as the Comet cubicle, must be positioned:

■between the low voltage switchboard and the input power switch for Comet series 11 and series 33 (see figure 26);

■between the Comet load output terminals and the load for Comet series 31 (see figure 27).
