Usage of the offboard fleet Charger Energy Storage CH 5-1.2 as an on-board charger is
strictly prohibited. Off-board fleet Charger Energy Storage CH 5-1.2 and on-board char-
gers are not interchangeable.
Input Voltages beyond 265 V AC may lead to irreversible damage of the components and
uncontrollable behavior.
CAN communication interfaces must not be used by an external device to take control of
the system.
Subsequent “hot un-/plugging” (i.e. removal of the DC connections during charge) will
damage to connectors and can lead to fatal malfunctions.
No additional loads other than the original battery packs may be attached to the Charger
Energy Storage CH 5-1.2.
The maximum number of 2 attached Energy Storages ES 5-2.4 per Charger Energy Storage
CH 5-1.2 must not be exceeded.
Modification of the cable harness is strictly prohibited, i.e. no different or additional con-
nectors than originally equipped may be applied.
A cable designed for dual battery charge shall not be used to charge a single battery (pos-
sibility of short circuit at open ended connector)
Chargers Energy Storage CH 5-1.2 may not be used in parallel on the DC side
The System of Charger Energy Storage CH 5-1.2 and Energy Storage ES 5.2.4 (including
cables) shall not be placed in an area with a distance to radio-transmitter (mobile phones,
Wlan, Bluetooth, etc.) less than 1 m.
4.5.2 Functional description
Communication is protected against errors in message transmission.
Batteries are inherently safe
A battery voltage less than 36 V will be treated as an under voltage condition and the sys-
tem will be shut down. The normal operating voltage range is 36 to 54.6 V. At voltages
above 54.6 V, an overvoltage condition will be detected in both the Charger Energy Stor-
age CH 5-1.2 and attached Energy Storages ES 5-2.4. This detection will initiate a shut-
down of the system.
