“AC OUT”. The terminal points are indicated clearly. From left to right: “G” (earth),
“N” (neutral), and “L” (phase).
The AC input cable can be connected to the terminal block containing the word “AC
IN”, the terminal points are indicated clearly from left to right “L” (phase), “N”
(neutral), and “G” (earth).
The current which is switched through to the output (AC OUT) is not fused.
External fuses or current limiters have to be installed.
1.6 Optional Connections
A number of operational connections are possible:
1.6.1 Second Battery
The “Stackable Inverter” has a connection for charging a starter battery.
For connection, see page 29.
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

. For connection, see page 29.
1.6.3 Battery Temperature Sensor (BTS-3)
The battery temperature sensor supplied with the product may be used for temperature
compensated charging, see page 29.
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 “Stackable Inverter” 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 32. The batteries must be connected in accordance with page 32.This requires
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:
1. No more than 5 units should be connected in parallel.
2. Only identical models should be connected in parallel.
3. Ensure sufficient battery capacity is available.
4. The prescribed cable cross sections (between battery and distribution point) must
be multiplied with the number of appliances to be connected in parallel.
5. Position the products close to each other but ensure there is adequate clearance for
ventilation minimum 20 cm. For better ventilation, please install the fan cover
