– Do not reload after only using for a short

time. (Discharge by at least 20 % before
recharging.)

– Recharge batteries from time to time if

they are not used for long periods.

– The contacts must be covered in order

to ensure that no short circuit can occur
through metallic bridging (e.g., by tools).

Wetrok permanently installed 24 V / 10 A
charging unit with a 220 – 240 V, 50 Hz,
280 W mains connection for maintenance-
free, sealed lead batteries. The charging
unit is fully automatic, and requires no
