Tighten the LT 320 control panel:
Establish an installation opening as in Fig. 1.
Mark out the hole pattern (see Fig. 1).
Pre-drill the holes (to 2 mm).
Use four x 2.9 cylinder head screws.
Ensure that the screws only gently touch against the front panel (until it is
no longer possible to move the panel).
2.2 Electrical connection
The L T 320 control panel is intended for connecting to Schaudt solar regulators
F LRM 1218 (MPP regulator)
F LR 1218 (series regulator)
Appropriate 4-pin connector cables (LRM 1218) and a connector set

Y ATTENTION!
Be sure to observe the correct polarity when plugging the cables into the
leisure battery. An incorrect connection will result in irreparable damage to
the solar regulator and panel.
Y If the connector cable is too long, it can be coiled up and secured at a
suitable place within the vehicle (such as near the solar regulator). It is
also possible to shorten the cable and fix to it four new 6.3 mm flat pushon contacts (not included in the delivery).
