• High temperature can accelerate the aging of insulation materials and significantly lower the

reliability and lifespan of the L1000-A.

For the temperature and humidity requirements of the L1000-A, see Table 1.

Cleanness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal

components and contact points, especially when indoor relative humidity is low. In the worst case,

electrostatic adsorption can cause communication failure.

The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion and

premature aging of components, as shown in Table 3.

Cooling

The L1000-A adopts left to right airflow for heat dissipation. Plan the installation site for adequate

ventilation.

• Leave at least 10 cm (3.94 in) of clearance at the inlet and outlet air vents.

• The installation site has a good cooling system.
