Hydraulic Elevators
Hydraulic Elevators need battery backup to help prevent
stranding passengers. To keep the elevator from moving
when it’s been manually shut down for maintenance, the
NEC
disconnecting means through an auxillary contact.
However, an unintended consequence can be passengers
getting stranded because of devices that open
automatically (circuit breakers and disconnects utilizing a

molded case switch with a trailing fuse block) will operate
with a fault on their loadside. That operation also disables
the battery backup and strands passengers. That’s why the
Power Module has a non-automatic fusible shunt trip
switch. If the Power Module has a fault on its loadside, the
fuses open and the battery stays enabled. Thus the Power
Module ensures that battery power is enabled when the
passengers need it to exit, and disabled to allow safe main-
tenance of the elevator and hoistway.
