Location Considerations
To fully experience the benefits and reliability of the PCS design, follow the provided guidelines:
The PCS unit is rated IP55 and configured for outdoor installations.
Install the PCS in an accessible location following local requirements or European Standard for
enclosure and door clearances and proximity to other equipment.
For optimal PCS life and performance, do not mount the PCS in direct sunlight, especially in hot
climates. If the unit must be mounted in direct sunlight, a metal sun-shield is recommended but
not required.
The PCS is forced-air-cooled. The cabinet is separated into two compartments: front and rear
compartments.
In the case of front compartment, a heat exchanger is mounted on the front door and air is
drawn in by the heat exchanger fans through vents at the lower part of the front door, and
exhaust air is emitted from vents at the higher part of the front door, as shown in Figure 6.
From the rear compartment, air is drawn in through vents at the lower part of the rear door, and
exhaust air is emitted from vents in the front of the roof. The air inlet and outlet must not be
blocked, and the installation location should be sufficiently ventilated to prevent the PCS heat
output from increasing the ambient temperature beyond the PCS’s rating.
