Location
The preferred installation is where the charger(s) can be located on a shelf,
protected against accidental contact with the lift truck or its forks.
With the charger on a shelf the risk
of damage to the charger or battery
cables is greatly reduced.
Avoid just placing the charger on
the floor next to the lift truck.
