Do not install the SUN2000 in places prone to body contact because the SUN2000 shelf and
heat sinks become hot during the SUN2000 operation.

The installation methods and position match the weight and dimensions of the SUN2000.
For details, see 10 Technical Specifications.

The wall is solid enough to bear the SUN2000.

The cable connection area faces downwards.

Install the SUN2000 vertically or lean it backward for at most 15 degrees.

The SUN2000 is installed in an appropriate height for ease of observing and operating
the monitoring panel.

The ambient temperature is below 50°C to ensure optimal SUN2000 operation and
extend the SUN2000's service life.

The SUN2000 should be installed in well ventilated environment to ensure good heat
dissipation.

The SUN2000 is not exposed to direct sunlight. Otherwise, the SUN2000 may overheat,
resulting in efficiency drop.

In residential areas, the SUN2000 is not installed on gypsum boards or walls made of
similar materials which have a weak sound insulation performance because the noises
generated by the SUN2000 disturb residents.

To ensure good heat dissipation and reserve enough space for installing the SUN2000,
the SUN2000 is at least 200 mm, 500 mm, 300 mm, and 1000 mm away from objects on
its both sides, top, bottom, and front respectively, as shown in Figure 4-2.
Figure 4-2 Minimum installation clearance

When installing multiple SUN2000s, install them in the same line if sufficient space is
available and install them in triangle mode shown in Figure 4-3. If no sufficient space is
