IMPORTANT SAFETY
INSTRUCTIONS
SAVE THESE INSTRUCTIONS.
This publication contains important instructions for 6- and 12-pole solar
combiner enclosures, catalog numbers 1000-SB006 and 1000-SB012, that must
be followed during installation and maintenance:
• Use 90 °C (194 °F) copper wire only.
• This product is intended for operation in an environment with a
maximum temperature rating of 40 °C (104 °F)
• For entry into the enclosure, use only UL-Listed raintight or wet location
hubs (for UL Type 3R, 12, and 13) that comply with the requirements in
the Standard for Conduit, Tubing, and Cable fittings (UL514B).
• Use only UL-Listed watertight hubs (for UL Type 4/4X) that comply
with the requirements in the Standard for Conduit, Tubing, and Cable
fittings (UL514B).
Bonding between conduit connections is not automatic and must be provided as part
of the installation.
SHOCK HAZARD: Disconnect and lock out power before entering or performing
maintenance on the enclosure.
SHOCK HAZARD: Normally-grounded conductors may be ungrounded and energized
when a ground fault is indicated.
SHOCK HAZARD: When the photovoltaic array is exposed to light, it supplies a DC
voltage to this equipment.
Follow National Electric Code, ANSI/NFPA 70, Requirements
The system installer is responsible for the following:
• Follow National Electric Code wiring methods
• Follow cUL certification requirements, including
CSA C22.2 No. 107.1-01, clause 154.5.2
• For Canadian installations, following the wiring methods per the
Canadian Electrical Code, Part II
• System grounding, if required by Section 250 of the National Electric
Code (DC input and output circuits are isolated from the enclosure)
• Install photovoltaic system grounding per the requirements of
Sections 690.41…690.47 of the National Electric Code

Planning for Installation
When planning the location for your solar combiner enclosure, consider the
following:
• Conduits
• Type of installation
• Product dimensions (see pages 10
and 11)
• Mounting requirements
• Connection to other equipment
• Enclosure rating
• Environmental conditions
• Future needs
Environment and Enclosure
Most applications require installation in an industrial enclosure to reduce the
effects of electrical interference and environmental exposure. Locate your
controller as far a possible from power lines, load lines, and other sources of
electrical noise, such as hard-contact switches, relays, and AC motor drives.
Rockwell Automation Publication 1000-IN002B-EN-P - April 2012
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.

2. Use a hole cutter or hole saw to create holes at the top and bottom of the
enclosure.
When using a hole cutter, place the punch on the inside of the enclosure and
draw it through to the outside.
Install the Conduit Connector and Grounding Adapter
Install the conduit connector (hub) and grounding adapter by following these
steps.
To guard against enclosure damage, align the conduit to prevent unnecessary stress on
the enclosure walls.
For conduit hubs, use only raintight or wet-location hubs that comply with the
requirements in the UL514B standard for Fittings for Conduit and Outlet Boxes.
1. Place the conduit connector (hub) and O-ring onto the conduit in the
desired locations.
2. Secure the conduit connector to the enclosure by using the locknut.
3. Install the grounding adapter as shown in Figure 2
and secure with the
locknut.
Make sure that the wiring terminal is positioned so that it will be accessible
after installation.
