2.2.2 Battery Installation Options and Wiring Diagram
Convection airflow battery cooling relies on proper spacing of batteries installed in the enclosure. Consistent spacing is
achieved by the use of Alpha's Battery Spacer clips. These easy-to-install clips snap over the tops of AlphaCell batteries
allowing for optimal airflow. For domestic applications, use one battery clip per 36V battery string for optimal spacing. For
international applications, use two clips per 36V battery string (See Fig. 2-5).
Adapt Smart AlphaGuard harness to legacy DM3X/DSM3/DSM3x connector — use Adaptor Cable, p/n 876-003-20
DSM3 / IDH4 (1 battery string) — use Battery Sense Harness, p/n 874-842-21
(Not required if SAG is installed with its sense harness).
DSM3 / IDH4x (2 battery strings) — use Battery Sense Harness, p/n 874-842-28
(Not required if SAG is installed with its sense harness).
DSM3x / IDH4x (3 battery strings) — use Battery Sense Harnesses, p/n 874-842-21 and 874-842-28
(Not required if SAG is installed with its
sense harness).
DSM3x / IDH4x (4 battery strings) — use Battery Sense Harness, p/n 874-842-20 and 874-842-28
(Not required if SAG is installed with its
sense harness).
AlphaGuard (external)
— use Battery Harness, p/n 875-090-32
Upgrade existing external AlphaGuard
to Smart AlphaGuard — use Retrofit Cable, p/n:
875-910-20 for one string
875-910-21 for two strings
875-910-22 for three strings
875-910-23 for four strings
Smart AlphaGuard (Embedded)
— use Battery Harness, p/n:
875-848-20 for one string
875-848-21 for two strings
875-848-22 for three strings
875-848-23 for four strings
