INSTALLATION
- Mount the device close to the battery / battery bank in an easily accessible location, so that a manual
emergency operation is possible.
- The installation location should be cool and dry if possible.
- Provide strain relief for the cables (at a maximum distance of 30 cm)
CONNECTION
- The batteries must be disconnected before installation!- The wire cross section of the connecting lines
to the batteries or battery banks must must be at least 25 mm². The dissipation of the heat loss in the
relay takes place via the connected lines. Dimension the cable cross section sufficiently (page 4)!
Please remember to fuse the cable correctly near the battery!- The wire cross section of the
control lines must be at least 1 mm².
- Terminal Minus: must be connected to the minus of the on-board power supply.
- Terminal C: Connection for an (optional) button for "Battery - parallel connection" (against minus).
- Terminal L: Connection for an (optional) external control LED (against minus)
- Terminal S: Connection for "Battery disconnection" (optional) to disconnect the batteries during the start
process or during charging with a charger with several outputs or to disconnect the batteries during bow
thruster operation. This avoids high cross currents during starting as well as possible interference with
sensitive loads connected to the service battery bank.
A voltage of > 8V (via a fused line, e.g. from the ignition lock, or control line around the starter motor and
carrying voltage only during the starting procedure) separates the two battery banks.
Attention: the manual operation of the buttons directly at the relay is not recognized by the con-
trol electronics!
Control lines:
1 button
3 External LED +
(no pre resistror)
2 Minus (GND)
