4 Mechanical installation
YThis device is intended for installation into a vehicle.
"For applications in which the cables provided are used to connect to an
EBL ... electroblock from Schaudt (as in Sections 5.2 and 5.3), the solar
charge regulator must be installed in the direct vicinity of the electroblock
(max. distance to front plate 30 cm).
"For other applications, a dry and sufficiently ventilated place in the insula-
ted interior is to be selected for installation. No condensation is allowed to
form on the device. To prevent a build-up of heat, ventilation holes facing
the living area must be provided in the upper and lower areas of the
place of installation. Its cross-section is based on the size and average
temperature of the place of installation.

"Ensure a minimum clearance to the surrounding fixtures and fittings:
FMaintain a gap of at least 5 cm on all sides (except mounted side).
FWhilst in operation, the ambient temperature must not exceed +45 C,
measured 2.5 cm away from the sides of the device.
"On a stable and even surface, attach the solar charge regulator to the
drillholes with two screws (Fig. 1, Pos. 5).

Damage to the solar charge regulator or fire damage to cable:
FTo protect the supply lines in the event of a short circuit, connect the
fuses directly to the positive pole of battery.
Select cable cross-sections in line with EN 1648-1/-2. The maximum current
load must not exceed 90% of the individual fuse rating.

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).
YSteps 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.

5.3 Connection to an EBL ... electroblock with 3--pin MNL con-
nection and adapter for starter battery
When using an electroblock which only has a 3--pin connection for a solar
charge regulator, an adapter for charging the starter battery can be retrofit-
ted. It is then possible to charge the leisure area and starter batteries simul-
taneously.
The following electroblocks (as of April 2008) can be used with the adapter:
FEBL 99
FEBL 100
FEBL 264-9
FEBL 240
FEBL 269

Establish the connection on the front of the solar charge regulator in the
following order:
"1. Connect the electroblock with cable X (connection cable EBL ...
(charge currents for batteries), Fig. 2, Pos. 2).
"2. Connect the electroblock with cable Y (SDTBUS, Fig. 2, Pos. 4).
"3. Fit the right flat vehicle fuse (15A or 20 A; Fig. 1, Pos. 1 or 2) into the
”Solar” fuse on the EBL ...
"4. Finally, connect solar modules to the solar charge regulator. Use wire
end sleeves for this.
YThe correct fuse rating is printed on the front plate of the EBL... electro-
block. See also the block diagram in the operating instructions for the
electroblock.
YSteps 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.
5.5 TF 50 A battery temperature sensor (optional)
The optional TF 50 A battery temperature sensor is used to implement bat-
tery temperature--controlled charging. The LRM 1218 solar regulator must
be fully isolated from the power for the sensor to be detected (unplug the
connectors for solar modules and batteries, and plug them in again after 30
seconds).
A battery temperature sensor can also be ”deregistered” by first unplugging
the connectors for solar modules and batteries on the LRM 1218, and then
disconnecting the temperature sensor.
Once the connectors for solar modules and batteries are plugged in again,
the sensor is ”deregistered” and no faults are displayed (bus system).
