9.3.2 Shock
The shock load of the BA1N energy storage devices is defined by the maxi‐
mum allowed acceleration in non-stationary use, e.g. during transport.
Function-impairing effects are avoided as long as the limits specified are
kept. Based on DIN EN 60721-3-3, the following values are applicable for
BA1N energy storage devices:
Size BA1N...
Maximum allowed shock load
(duration 6 ms)
Axial Radial
16 10 m/s² 150 m/s²

9.4 Degree of protection
BA1N energy storage devices are subject to the degrees of protection pur‐
suant to IEC 60529. It must always be ensured that the energy storage devi‐
ces – irrespective of their installation position – are not exposed to ambient
conditions outside of the applicable degree of protection.
