Display Unit Ddu 18 - Bosch e-GoKart PowerTrain Young Star Manual

4.5.3 Safety requirements
Bosch Motorsport
– Feedback current from Energy Storage 5-2.4
– Reverse polarity
– Overtemperature
– Disconnect during charge (detection only)
– The system may only be operated by instructed personnel.
– Charging shall be supervised constantly. Charging is only permitted in well-ventilated,
dry rooms.
– At voltages above 54.6 V damage of the Energy Storages ES 5-2.4 and the Charger
Energy Storage CH 5-1.2 are possible.
– Dis-/assembly of cables and connectors is permitted without applied voltage only. It
must be ensured that the Charger Energy Storage CH 5-1.2 is not AC connected and
that there is no voltage on the DC lines prior to installation.
– Connection of battery power terminals / comm. connector is only allowed after check-
ing that there is no voltage at the battery terminals.
– The Charger Energy Storage CH 5-1.2 shall be switched off (=indication LEDs off) be-
fore closing/opening electrical DC connections.
– Energy Storages ES 5-2.4 shall only be connected and disconnected in the Charger
Energy Storage CH 5-1.2 OFF state (LEDs off).
– The setup shall be protected from avoidable impacts (drop, water, mechanical shock).
– Components that show visible damage must not be used.
– Components which show faulty behavior (e.g. tripping AC fuse) must not be used.
– If any component shows a different behavior than stated in this document, the corres-
ponding BOSCH MOTORSPORT representative has to be informed before continu-
ation of use.
– Error codes and instructions have to be available for any user.
– Any terminals which could exceed voltages of 60 V DC or 30 V AC shall be protected
against contact.
– Harness Connectors shall prevent reverse-polarity.
– Any Operation with disconnected terminals on AC and DC side shall be avoided.
– Components must not be opened (does not apply to removable terminal covers).
– Excessive or insufficient tightening torque as well as forgotten washers might lead to
elevated contact resistances. Danger of overheating and fire!
– Electric interfaces shall not be exposed to mechanical forces or torques except for
mounting forces.
