Solar Combiner Enclosure 5
Environmental Ratings
The enclosure is rated for IP 66 and UL Type 3, 4, 4X, 12, and 13 applications
when used with the proper UL Type hub or conduit fittings. The enclosures are
constructed for either indoor or outdoor use, and provide a degree of protection
to personnel against incidental contact with the enclosed environment. They
provide a degree of protection against snow, windblown dust, splashing water,
and hose-directed water. They will be undamaged by the external formation of ice
on the enclosure and provide corrosion protection.
The unit is rated to function with a temperature range of -20 °C…40 °C
(-4 °F…104 °F).
Install the Solar Combiner
Enclosure
Follow these requirements during installation:
• Bonding between the grounding bushings and the equipment grounding
terminals must be provided in accordance with applicable codes.
• A 1/2-in. minimum electrical clearance must be maintained between the
grounding adapter wire terminal and electrically live components.
Prepare the Enclosure
Follow these steps to prepare the enclosure.
1.
From the table below, select the appropriate combination of conduit
connector and grounding adapter based on your type of installation, and
determine the required hole size in the bottom or side of the enclosure.
Holes must be at least 6 in. (15.24 cm) below the output terminal in the
enclosure side of the 12-pole assembly. When using 4 AWG wire in the
6-pole assembly, the hole must be at least 2 in. (5.08 cm) below the output
terminal in the enclosure side.
For more details, reference table 7.2 of UL 1741.
