1.6 Optional Connections
A number of operational connections are possible at the black connection box at the bot-
tom of the unit. Please remove the two screw to make them visible:
1.6.1 Second Battery
The “Combi-Gamma” has a connection for charging a starter battery.
For connection, see page 24.
1.6.2 Voltage Sense
Two sense wires may be connected to compensate possible battery cable losses
during charging. Use wires of at least 0.75 mm
2
. For connection, see page 24.
1.6.3 Battery Temperature Sensor (BTS-3)
The battery temperature sensor supplied with the product may be used for tempera-
ture compensated charging, see page 24.
The sensor is insulated and must be mounted on the batteries minus pole.
1.6.4 3 Sets of Auxiliary Relay (RY1, RY2, RY3) Output
The “Combi-Gamma” provides 3 sets of Auxiliary Relays for users to connect to
other appliances or to output the alarm signals. 3 sets of relays can be programmed
for respective function. (E Group Constants) and can be practically applied which is
one of the greatest features.
1.6.5 Parallel Connection
The product can be connected in parallel using several identical modules, please
see page 27. The batteries must be connected in accordance with page 27.This re-
quires interconnecting the products with the package of a special box, parallel box,
to be supplied by factory in conjunction with a connection diagram.
Parallel connection requires compliance with the following conditions:
No more than 5 units should be connected in parallel.
1.
Only identical models should be connected in parallel.
2.
Ensure sufficient battery capacity is available.
3.
For example : 12V: 20% inverter power (3000W=600Ah)
24V :10 % inverter power (3000W=300Ah)
Described cable cross sections (between battery and distribution point) must be
4.
multiplied with the number of Combi-Gamma to be connected in parallel.
Position the Combi-Gamma close to each other but ensure there is adequate
5.
clearance for ventilation minimum 20 cm.
The optional BTS, voltage sensor and optional remote control panel (RCP) must
6.
be connected to Master.
The cables for each appliance must be equal in length (AC and DC)
