IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT INSTRUCTIONS FOR THE PT-100 MPPT CHARGE CONTROLLER
THAT SHALL BE FOLLOWED DURING THE INSTALLATION AND OPERATION OF THIS PRODUCT.
Before using the PT-100, read all instructions and cautionary markings. Also, be sure to review
the individual manuals provided for each component of the system. The installation instructions
are for use by quali
fi
ed personnel only. Do not perform any installation or servicing other than
that speci
fi
ed in this owner’s manual unless you are quali
fi
ed to do so. Incorrect installation or
servicing may result in a risk of electric shock,
fi
re, or other safety hazard.
Safety Symbols
The following safety symbols have been placed throughout this manual to indicate potentially
dangerous or important safety instructions.
WARNING:
This symbol indicates that failure to take a speci
fi
ed action could result in
physical harm to the user.
CAUTION:
This symbol indicates that failure to take a speci
fi
ed action could result in
damage to the equipment.
Info:
This symbol indicates information that emphasizes or supplements important
points of the main text.
GROUND:
This symbol indicates the connection point intended for the equipment-
grounding conductors, and is located in the wiring compartment.
Safety Precautions
• All electrical work must be performed in accordance with local and national electrical codes.
• This product is designed for indoor/compartment installation. It must not be exposed to rain,
snow, moisture, or liquids of any type.
• There are no user-serviceable parts contained in this controller; do not disassemble or attempt
to repair. Refer servicing to quali
fi
ed service personnel.
• Since a charge controller utilizes PV power and batteries, power may be present at more than
one point. To reduce risk of electric shock, ensure both battery and PV power are disconnected
prior to performing maintenance. Turning off the charge controller will not reduce this risk, the
charge controller must be totally disconnected from all sources of power.
• When exposed to sunlight, PV modules can generate current and voltage on its output wires/
terminals. Before making any connections, de-energize the PV modules, either by removing them
entirely from light or completely covering their front surface with an opaque (dark) material.
• Listed or labeled equipment shall be installed and used in accordance with any instructions
included in the listing or labeling.
• Always verify proper wiring prior to starting the charge controller.
• Use only copper wires with a minimum temperature rating of 167°F (75°C).
• Torque all wire connections to the required torque values.
• The charge controller must be properly mounted and installed in a proper location. See Section
2.3 for information on mounting and location requirements.
• Overcurrent protection (i.e., fuses/circuit breakers) is not provided as an integral part of this
charge controller. Overcurrent protection for the PV and battery wiring must be provided as
part of the system installation.
• This device is provided with integral PV Ground Fault Detector/Interrupter (GFDI). Normally
grounded conductors may be ungrounded and energized when a ground-fault is indicated.
• The heatsink of the controller can exceed 167°F (75°C); to reduce the risk of burns, do not touch.
• Internal capacitors may have stored energy. Once all sources of power has been disconnected,
wait at least 5 minutes before removing the access cover.
