Control panel solar charge currents (optional special configura-
tion; cable delivered with the panel)
TF 50 A* Temperature sensor (special configuration, see also Section
5.5)
Establish the connection on the side of the solar charge regulator in the fol-
lowing order:
"
1. Connect the two fuse holders with fuses to the connection cable in ac-
cordance with the circuit diagram in Fig. 4. Use the flat push--on con-
tacts (6.3 x 0.8) without sleeve for this (Fig. 1, Pos. 5). After crimping,
attach the insulating sleeves (Fig. 1, Pos. 7). Insert the two fuses.
"
2. First connect the connection cables for living area battery and starter
battery to the solar charge regulator, observing the polarity of the con-
nections. Use wire end sleeves for this (not included in the delivery).
"
3. Connect the cables for leisure area battery and starter battery to the
batteries.
"
4.
Finally,
connect solar modules to the solar charge regulator. Use wire
end sleeves for this (not included in the delivery).

Steps 5. ... 9.
ONLY
when a TF 50 A temperature sensor is fitted (optio-
nal):
"
5 Clamp the TF 50 A battery sensor to one of the terminals (preferable
the negative terminal) of the leisure area battery (note: this is NOT an
electrical connection -- only the temperature of the battery terminal is
read with this mechanical connection; this is virtually identical to the
internal temperature of the battery)
"
6. Guide the cable through the vehicle to the LRM 1218 solar charge
regulator.
"
7. Plug the TF 50 A battery sensor connector into the LRM 1218 solar
charge regulator.
"
8. Secure the battery sensor cable at a suitable place (particularly near
the connector on the LRM 1218 to prevent the 2-pin connector from
coming loose).
"
9. Unplug the ”Solar modules” and ”Leisure area and starter batteries”
connectors from the LRM 1218 and plug them back in again after 30
seconds. This ”registers” the sensor.
Disconnect in the reverse order.
