Option Description
BPSU672
DK424i cabinet power supply. This power supply can operate with 120VAC, 208VAC, or 240VAC
connected as the system’s primary AC power source. It automatically detects and adjusts to the
type of primary AC power that is connected. The power supply is included with each cabinet
ordered but must be installed in the field.
Standard 9 ft. AC
power cords for AC120VAC/15A are provided with DK424i Base or Expansion
cabinets. When AC208V or AC240V power is used, a special AC cord, BACL240, is required for
each cabinet power supply and must be ordered separately.
RPSB2
Cabinet power strip for 120VAC primary power – provides three standard 120VAC/15A outlets
(NEMA 1-15R) and nine ft. AC power cord with standard 120VAC/15A plug (NEMA1-15P). This
unit is field installed inside system cabinet side panels.
One RPSB2 is required for two or three cabinet systems if the local electric code allows only one
AC power cord to be connected to the system.
Note If the local electric code allows only one AC power cord to be connected to the system,
208VAC or 240VAC must be used as primary AC power for systems with four or more
cabinets.
One RPSB2 is required for a three or four cabinet system if the local electric code allows two AC
power cords connected to the system.
Two RPSB2s are required for a five cabinet system if the local electric code allows two AC power
cords connected to the system.
BPSB240
Cabinet power strip for 208VAC or 240VAC primary power. Provides three 240VAC/20A outlets
(NEMA 6-20R) and 9ft. AC power cord with a standard 240VAC/20A plug (NEMA 6-20P). This
unit is field installed inside system cabinet side panels.
One BPSB240 is required for two or three cabinet systems.
Two BPSB240s are required for four or five cabinet systems.
Notes
♦ Local electric codes allow only one AC power cord to be connected to the system when
using 208VAC or 240VAC as the primary AC power.
♦ If using 208VAC as primary power, the plug on the BPSB240 AC power cord (NEMA
6-20P) may have to be changed by a certified electrician depending on local electric
codes.
BACL240A
AC208V or AC240VAC nine ft. power supply cord. This cord must be used when the system is
powered by 208VAC or 240VAC. One cord is required for each cabinet power supply and must be
ordered separately only if using 208VAC or 240VAC as the system primary AC power.
Note The cord is equipped with a 250VAC/20A plug (NEMA 6-20P) which is standard for
240VAC. If using 208VAC as the system primary power this cord may not exit the
cabinet, a BPSB240 power strip is required and the power strip plug may have to be
changed by a certified electrician depending on local electric codes.
PBTC-3M
A three-meter battery cable used to connect reserve power batteries to the system power supply
when the system has less than three cabinets. One reserve power cable is required for each
cabinet in a one or two cabinet system (wall or floor mount). The cable connects the DK424i
cabinet power supply directly to the battery terminals (a BBDB is not required).
BBDB
DK424i reserve power battery distribution box is required when connecting reserve power
batteries to three or more cabinets (wall or floor mount). The box is field installed into one of the
DK424i cabinet side panels.
The BBDB provides 7 BBTC2A-2.0M, battery distribution cables to connect reserve power from
the BDDB box to each individual cabinet power supply.
One or two BBTC1A-2.0M must be ordered separately when using the BBDB battery distribution
box.
