2 Overview
Function
simultaneously.
Reinforces the cabinet so that
the cabinet meets the
requirements of 9 degree
seismic fortification intensity.
Prevents water from dropping
into the cabinet, protecting the
cabinet to IP21.
If you need to install the cabinet
against a wall, install a top
outlet kit to meet heat
dissipation requirements.
Install this subrack when the
UPS is equipped with a
backfeed protection card and dry
contact extended card.
Provides extended monitoring
ports: five routes of relay output
ports and five routes of input
ports.
Detects mains and bypass
backfeed and provides
protection.
 Monitors battery voltages
and temperatures as well as
battery string charge and
discharge currents.
 Communicates with the UPS
over Modbus.
 Detects current leakage and
generates alarms. When
equipped with a remote trip
switch, the detector protects
devices and prevents the
outbreak of a fire.
 Detects battery grounding
failures and generates alarms
when the ground leakage
current exceeds the specified
value.
Ambient temperature and
humidity sampling board
applicable to batteries.
Transmits bus synchronization
signals in a dual-bus system.
