IMPORTANT

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

Nameplate Data

Figure 1 - Nameplate Sample

Each solar combiner enclosure has a nameplate on the enclosure or enclosure
door, similar to the example shown below.

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.
