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.

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.
