4.2.6 Main contactor and key connection
- The connection of the main contactor can be carried out following the drawing in
the figure.
- The connection of the battery line switches must be carried out following ZAPI
instructions.
- If a mechanical battery line switch is installed, it is strongly recommended that
the key supply to the inverter is open together with power battery line (see
picture below); if not, the inverter may be damaged if the switch is opened
during a regenerative braking.
- An intrinsic protection is present inside the logic when the voltage on the battery
power connection overtakes 40% more than the battery nominal voltage or if the
key is switched off before the battery power line is disconnected.
4.2.7 Insulation of truck frame
U
As stated by EN-1175 “Safety of machinery – Industrial truck”, chapter 5.7,
“there shall be no electrical connection to the truck frame”. So the truck frame
has to be isolated from any electrical potential of the truck power line.
