4.3 OPERATION WITH INTERNAL MANUAL MAINTENANCE BYPASS.
If the internal maintenance bypass is activated using the appropriate procedure, the load is powered directly from
the maintenance bypass, while the UPS is separated from the power supply and can be switched o .
This operating mode can be selected for maintenance to be carried out on the system so that the necessary actions
can be performed by service personnel without having to disconnect the power supply to the load.
4.4 OPERATION WITH EXTERNAL MANUAL MAINTENANCE BYPASS.
The external manual maintenance bypass connection is not allowed when the internal transformer
is placed on output or bypass.
For any further information, please contact SOCOMEC UPS.
4.5 OPERATION IN GE CONFIGURATION.
MASTERYS™ can be operated in conjunction with a generator (GE).
With a generator, the frequency and voltage ranges of the auxiliary mains can be increased to accept the instabil-
ity of the GE and at the same time to avoid operation from the battery or risks of out-of-synchronisation switching
onto the bypass.
The use of the GSS interface, described in the options section, also increases the amount of diagnostic information
exchanged between the continuous power system and the generator.
