11.1. A: Connection overview

A	AC input M6 (generator input) AC IN-1. Left to right: L (phase), N (neutral).
B	2x RJ45 connector for remote panel and/or parallel and 3-phase operation.
C	AC output M6 AC OUT-1. Left to right: L (phase), N (neutral).
D	AC output M6 AC OUT-2. Left to right: N (neutral), L (phase).
E	Terminals for: (left to right) Voltage sense Temperature sensor Aux input 1 Aux input 2 GND-relay Starter battery plus + (starter battery minus must be connected to service battery minus) Programmable relay contacts K1 Programmable relay contacts K2
F	Double M8 battery minus connection.
G	Double M8 battery positive connection.
H	Connector for remote switch: Short left and middle terminal to switch “on”. Short right and middle terminal to switch to “charger only”.
I	Alarm contact: Left to right: NC, NO, COM.
J	AC input M6 (shore/grid supply) AC IN-2. Left to right: L (phase), N (neutral).
K	Push buttons for set-up mode
L	Primary ground connection M8 (PE).

11.5. E: Charge characteristic

4-stage charging:

Bulk

Entered when charger is started. Constant current is applied until nominal battery voltage is reached, depending on temperature and input voltage, after which constant power is applied up to the point where excessive gassing is starting (14.4 V resp. 28.8 V, temperature-compensated).

Battery Safe

The applied voltage to the battery is raised gradually until the set Absorption voltage is reached. The Battery Safe Mode is part of the calculated absorption time.

Absorption

The absorption period is dependent on the bulk period. The maximum absorption time is the set Maximum Absorption time.

Float

Float voltage is applied to keep the battery fully charged.

Storage

After one day of float charge the output voltage is reduced to storage level. This is 13,2 V resp. 26,4 V (for 12 V and 24 V charger). This will limit water loss to a minimum when the battery is stored for the winter season. After an adjustable time (default = 7 days) the charger will enter Repeated Absorption mode for an adjustable time (default = one hour) to ’refresh’ the battery.
