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 by following local requirements or Australian Standard
for enclosures, door clearances, and proximity to other equipment.
For optimal PCS life and performance, it is suggested not to 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 the front compartment, the fan circulates internally and transmits heat to the
external environment through the case for heat dissipation, as shown in figure 6.
From the rear compartment, the air is drawn in through vents at the lower part of the rear side,
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.
