Installation

3.1.3 Accessories

Included with the inverter hardware are two sheet metal side shields, which can
be used to cover the open ends of the air inlet channel as shown in Figure 3-10,
and are intended to minimize nesting in the air channel by wildlife. Two shields
and associated screws are included.
Use of the shields does not significantly reduce airflow into the inlet filter, as the
rear side of the air channel is open, and thermal testing with the shields in place
has verified there is no associated operational degradation or derating of the
inverter due to their use as long as the rear access remains open.
To use the shielding plate, please refer to the installation method in Figure 3-10.
Tighten the screws to a torque value of 40 lbf-in (4.5 N.m)
