Electrical connection to the battery
INFO:
The EFOY Pro charges the connected battery and the battery supplies the
power to the application or to the electrical loads.
The EFOY Pro must only be used to charge lead batteries that conform to
the technical specifications of the device (see chapter 3.3 "Specifications"
on page 16).
The EFOY Pro can charge 12 V and 24 V batteries (Factory settings: lead
batteries; Adjustable: LiFePO4) and automatically detects which battery
voltage is connected.
The charging parameters for automatic mode can be adjusted individually
using the expert menu in the operating panel (see chapter 5.2.5 "Expert
menu" on page 43) or using a computer (see the user manual for the in-
terface adapter).
The settings and parameters for LiFePO4 batteries can be found in chap-
ter 5.2.5 "Expert menu" on page 43.
To protect the battery, the additional use of deep battery protection is
recommended to disconnect the load from the battery when the battery
voltage is low.
Check polarity before you connect the device.
Power line
Sense line
•
The charge line comprises four lines. The two
power lines charge the battery with electricity.
The two sense lines measure the battery volt-
age.
•
The following cable cross-sections are recom-
mended to minimize ohmic drops in the charge
line, if the battery charge line supplied is not
long enough:
Length
Minimum cable cross-section
< 5 m / 16.4 ft
2.5 mm² / 0.004 sq in AWG 13
5 – 10 m / 16.4 – 32.8 ft
4 mm² / 0.006 sq in AWG 11
10 – 15 m / 32.8 – 49.2 ft
6 mm² / 0.009 sq in AWG 9
