② Up to 3 battery banks can be connected to the charger. In single battery bank
installations do not use battery bank outputs 2 and 3, always connect the main battery
to output 1. Output 1 has charge priority, followed by output 2 and finally output 3.
Each output is capable to deliver the full charge current. For more information about
the smart charge handling between all outputs, please check chapter 3.1.
③ Since the Omnicharge
current per output, no minimum battery capacity is given. Omnicharge
mixed use of small and large batteries on each individual output. As rule of thumb, the
minimum battery capacity should be at least twice the charge current and the
maximum battery capacity ten times the charge current. For example, an OC
with the maximum charging current set to the default 40A, has a minimum
recommended battery capacity of 80Ah and a maximum capacity of approx. 400Ah.
Always consult the battery's datasheet for maximum charge current
recommendations!
④ If you wish to use this charger in a fixed installation, it is advisable to connect the
charger to a switched AC socket to turn it off completely. In this case, please make sure
to avoid having the batteries still connected to the charger for a prolonged time
without the AC connected. This can slowly discharge the batteries. Another option is to
connect a switch to the remote on/off terminals of the charger. This way the charger
only goes to standby/sleep mode and no current is drawn from the connected
batteries.
The schematic in this chapter shows a typical standalone installation. No guarantees are
given on the compliance of any local electrical regulations. Please make sure that the
complete installation is made in accordance to all locally applicable electrical regulations.
This Class I product must be earthed! Always connect the PE wire or chassis ground screw at
the bottom of the enclosure to your central ground (vehicle chassis, grounding system of
your boat etc.)
Always connect the negative (-) cable directly to the negative terminal of the battery, or to
the "loadside" of a current shunt. Always keep positive and negative cables close to each
other to minimize electromagnetic fields. Double check for correct polarity, before
connecting the battery cables to the battery! Wrong polarity may damage the charger.
