7. A spacing of 40 mm (1.58 inch) around the unit is required.
8. To ensure sufficient airflow when mounting the unit in enclosed spaces, two
lid openings (one for the air inlet and the other for the air outlet) have to be
provided. Do not block these air inlets and outlets when mounting the
Remote Unit. The size of each opening must equal at least 17 x 17 cm
(290 cm

). Make sure, too, there is no thermal short circuit between the air
inlet and air outlet.
If any different or additional mounting material is used, ensure that the mounting
remains as safe as the mounting designed by the manufacturer. Ensure that the
static and dynamic strengths are adequate for the environmental conditions of the
site.
The mounting itself must not vibrate, swing or move in any way that might
cause damage to the Remote Unit.
