Electrical connection
DANGER!
Danger of short circuit.
Connect the EFOY Pro 12000 Duo fuel cell only without voltage to
prevent a short circuit.
DANGER!
Danger due to unbalanced charging of batteries.
Always install a battery equalizer in a serial connection of several 12 V
batteries for a higher nominal voltage of 24 V DC or 48 V DC.
The responsibility of a proper installation and usage of the application
underlie to the user.
WARNING!
All electrical work must only be carried out by qualified electrical
technicians in accordance with the relevant legal provisions.
Laying cables incorrectly or using the wrong cable size may result in a
fire hazard.
All connected cables must have sufficient insulation and adequate proof
voltage, and the connectors must be scoop-proof. The laying of un-
insulated cables and pins is not permitted.
CAUTION!
Compare installed circuit breaker tripping characteristics with installed
battery parameters.
High battery capacities can cause high inrush currents.
INFO:
The EFOY Pro 12000 Duo must be connected to the battery using a fused
circuit. Fuses have to confirm to the maximum currents as specified, see
chapter 3.3 "Specifications" on page 18.
Preferably run separate lines for charging (power) and for voltage
measuring (sensor) to the battery, otherwise the flow of current will
cause false voltage readings.
