LC/D 107 must not be exposed to direct sunlight.
2.2 Mounting
Before mounting, remove the transport protectors, if any, from
inside the cabinet.
Mount the LC/D 107:
• on a plane wall surface,
• with the Pg cable entries pointing downwards (additional Pg
cable entries, if required, must be fitted in the bottom plate of
the cabinet),
• with four screws through the mounting holes in the back plate
of the cabinet, see fig. 1. The mounting holes must be bored
with a 4 mm bore. Fit the screws into the mounting holes and
tighten securely. Fit the plastic caps supplied with the
controller on the screws (IP65).
Figure 1 shows the internal construction of the LCD 107
