Eaton 93E Generation 2 UPS 100-200 kVA
(380/400/415V)
3.4.5
The optional internal maintenance bypass switch (MBS) for 100-120 kVA units
consists of input and bypass input switches, an output switch and a
maintenance bypass switch. The input and bypass input switches are used to
control the AC input to the UPS. The output switch is used to control the inverter
output. The MBS enables partial isolation of the UPS so that a limited number of
components can be serviced without interrupting power critical systems.
3.4.6
93E units are able to trip external battery breakers through 24 VDC OVT control.
3.5
The battery system is in an external cabinet. The battery system provides
emergency short-term backup power to safeguard operation during brownouts,
blackouts, and other power interruptions. The battery system is equipped with
lead-acid batteries.
3.6
The following basic UPS system configurations are possible:
•
Single UPS with 1-4 external battery cabinets
•
Single UPS with external batteries and accessory cabinets
The UPS system configuration can be enhanced by adding optional accessories
such as a remote emergency power-off (remote EPO) control, or MiniSlot
communication cards.
