Cable Routing
Cooper Crouse-Hinds provides all of the needed cables for internal wiring
of this system. All connections use #10 AWG wire. This kit is also
provided with 15' length of #10 AWG 2 conductor cable for connection
from the system terminal block to the solar panel.
Note that since this system may supply power at any time during
operation, all circuit breakers must be in the OFF position before
making any connections. If located in a Class I, Division 2 area, no
wiring connections should be made at all until the area has been
determined to be cleared of any hazardous gases. Terminal
connections may cause arcing and sparking when attaching wires.
All wiring which is external must be secured and properly protected from
the environment per local code. Wiring of equivalent size and type can be
substituted in this system for load connection if required. Cooper Crouse-
Hinds will not be responsible for damage due to connection of this system
to a non-hazardous rated load in a hazardous area.
Circuit Protection
Circuit protectors are provided with this system. These are DIN rail
mounted and have been sized to meet the load requirement and
photovoltaic panel and battery input power of the system. These are
supplied pre-wired to their respective terminal blocks. Make sure that
circuit protectors are in the OFF position when making or changing
connections to this system, and before servicing and maintaining any of the
system components. For hazardous location equipment, third-party
approved Class I, Division 2 circuit protectors have been supplied, which
are acceptable for use in Group A, B, C, and D areas. Standard location
circuit protectors must never be used in place of hazardous location circuit
protectors.

Maintaining the System
To prevent injury, death, or damage to your photovoltaic system,
extreme caution should be taken whenever entering the control cabinet
due to energized components.
Photovoltaic panels generate power whenever exposed to ANY light.
Cover the panel entirely prior to wiring or servicing with an opaque
cover.
Batteries are intended to store energy, and will shock, spark, or explode
if the terminals are touched or crossed.
Prior to installation or servicing, switch all disconnects to OFF position
and use only insulated tools.
The following list of maintenance and inspection duties must be performed
at least once every 6 months to ensure optimal performance and safety of
this equipment. Always follow local code when performing maintenance
and inspections, especially when in hazardous locations in which the
system may present a source of ignition for nearby combustible materials.
Maintain only during times of shutdown. NFPA 70B maintenance schedule
is to be followed.
1.
Verify that the correct battery type has been selected on the
controller.
2.
Verify that the system is charging within the rated current and
voltage levels listed.
3.
Check that all components are securely mounted and are free of
excess dirt, corrosion, and/or insects.
4.
Check that airflow around the controller, battery, and photovoltaic
module is not impeded for cooling and ventilation.
5.
Verify that water is not collecting inside of the enclosure or pole.
6.
Verify that the current system conditions are indicative of the
current controller functions (for instance, if sunlight is present, the
photovoltaic module should be charging the battery until full and
operating the load).
7.
Check to see that all bolts and mounting components are
structurally intact and free of corrosion and dirt.
8.
Check for degradation of all associated cabling and cable glands.
9.
Panel should only be cleaned with a soft cloth or sponge using
water only. Steam/aggressive cleaners/abrasives should never
be used. To avoid cracking, wash with water which is equal to
the ambient temperature.
10.
Weep holes and louvers must be free from debris.
To prevent injury, death, or damage to your photovoltaic system, open
door carefully - battery may be leaking corrosive fluids.
11.
Ensure water is not leaking into enclosure through any orifice.
We recommend an Electrical Preventive Maintenance Program as
described in the National Fire Protection Association Bulletin NFPA 70B:
Recommended Practice for Electrical Equipment Maintenance
(www.nfpa.org).
