Wiring the UPS
External Battery Connections
(Deep-Cycle Lead-Acid Batteries Only)
The UPS supports a user-supplied and assembled 24V DC (for SMART1524ET) or 48V
DC (for SMART1548ET) battery system. The batteries used must be rechargeable,
deep-cycle lead-acid type. Select batteries that meet your temperature requirements.
Connect batteries into a 24V DC (SMART1524ET) or 48V DC (SMART1548ET) UPS
system, as shown below. A battery bank of at least 100Ah, but not more than 200Ah,
is recommended. For the battery set, the recommended battery cable gauges are
6 AWG for the SMART1524ET and 8 AWG for the SMART1548ET, with a maximum
recommended length of 6.56 ft. / 2 m. The SMART1548ET requires a 48V 70A rated
fuse bank. The SMART1524ET requires a 24V 150A rated fuse bank. The battery
system attaches to the UPS via the included External Battery Connection Kit (refer to
the External Battery DC Connector Cable Assembly instruction sheet for how to wire
the external battery system to the UPS).
