4 Mechanical installation

Y This 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:

F Maintain a gap of at least 5 cm on all sides (except mounted side).

F Whilst 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).

Establish the connection on the side of the solar charge regulator in the following 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 contacts (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 connections. 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).

Y 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.

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 retrofitted. It is then possible to charge the leisure area and starter batteries simultaneously.

The following electroblocks (as of April 2008) can be used with the adapter:

F EBL 99 F EBL 100 F EBL 264-9 F EBL 240 F EBL 269

An LT 320 operating and display panel, for the display of solar charge currents, can be used as an optional accessory.

5.5 TF 50 A battery temperature sensor (optional)

The optional TF 50 A battery temperature sensor is used to implement battery 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).
