9. A spacing of 40 mm (1.66 inch) around the unit is required.

10. 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) must be

provided. Do not block these air inlets and outlets when mounting the

remote unit. The size of each opening must equal at least 12 x 12 cm (144

). Ensure that 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.
