Creating a priority circuit

You can create a priority circuit using a changeover relay whereby the exter-
nal voltage supply has priority over the generator, see circuit diagram
(fig. c, page 10):
Item Description
1 Load
2 AG113 changeover relay
3 Generator
4 External power supply
➤ Mount the changeover relay in a suitable position.
➤ Connect the wires following the circuit diagram (fig. c, page 10).

Connecting the starter battery

A
NOTICE!
The starter battery must have 12 V and a capacity of at least
60 Ah.
➤ Connect the positive terminal of the battery (fig. a 1, page 7) with the
positive battery terminal connection using a suitable cable:
– Cable lengths < 6 m: Cross-section of 16 mm²
– Cable lengths < 6 m: Cross-section of 25 mm²
➤ Connect the negative terminal of the battery (fig. a 2, page 7) with a suit-
able cross-section (see above) as follows:
➤ Connect the earth connection of the generator with the vehicle chassis.
➤ Remove any paint or rust from the chassis if necessary to ensure good
contact.
➤ Protect the connections with an anti-corrosive agent (e.g. lubricating
grease, lubricant/protective spray).
