Dimensions and Recommended
Clearances
The outer dimensions of the Sunny Boy 700U are shown in Figure 3-2. The Sunny
Boy must be mounted so that there is at least eight inches of clearance above the
heat sink that is mounted on the top of the inverter
Figure 3-2 Outer Dimensions of the Sunny Boy 700U
CAUTION: You must ensure that there is sufficient clearance
for heat dissipation above the Sunny Boy’s heat sink! In a nor-
mal operating environment with good ventilation, eight inch-
es of clearance is adequate. However, if the airflow to the
Sunny Boy is restricted or it is subjected to other abnormal op-
erating conditions, enough additional clearance (or forced
ventilation) must be provided to allow the heat that the Sunny
Boy produces to dissipate freely.
Note: If additional ventilation is required use the optional
Sunny Breeze fan that mounts to the heat sink.
Note: The National Electrical Code may require significantly
larger working clearances (see NEC Section 110.26).
