●
Connect the equipment grounding conductor of the components of the
electric drive and control system permanently to the main power supply
at all times. The leakage current is greater than 3.5 mA.
●
Establish an equipment grounding connection with a minimum cross
section according to the table below. With an outer conductor cross
section smaller than 10 mm
2
(8 AWG), the alternative connection of two
equipment grounding conductors is allowed, each having the same
cross section as the outer conductors.

Battery safety
Batteries consist of active chemicals in a solid housing. Therefore, improper
handling can cause injury or property damage.
Risk of injury by improper handling!
●
Do not attempt to reactivate low batteries by heating or other methods
(risk of explosion and cauterization).
●
Do not attempt to recharge the batteries as this may cause leakage or
explosion.
●
Do not throw batteries into open flames.
●
Do not dismantle batteries.
●
When replacing the battery/batteries, do not damage the electrical parts
installed in the devices.
●
Only use the battery types specified for the product.
