WARNING! STOP IMPORTANT SAFETY INSTRUCTIONS
READ ALL INSTRUCTIONS AND SAFETY WARNINGS PRIOR TO INSTALLATION
NOTE: SAVE THESE INSTRUCTIONS
This manual contains important instructions that shall be followed during installation and maintenance of the system. This manual should be stored near the product’s installation and must be available at all times. This product is intended for operation in an environment having a maximum temperature of 75°C. This product is only to be installed by qualified personnel. These installation instructions are for qualified personnel only and the instructions herein are provided for those individual(s) only. To reduce the risk of electric shock, injury or death, all wiring and connections must be performed by qualified personnel. Do not perform any installation or service other than that to which you are qualified to perform. Protect you and all persons and property during installation and servicing of this equipment. If you have any doubt concerning your competence or expertise, consult a qualified expert to perform the installation.

Lethal voltages are present during the installation, operation and service of this equipment. Proper precautions must be taken at all items to ensure the safety of the service personnel. At all times follow state and federal occupational safety and health administration (OSHA) guidelines and regulations. Utilize proper Personal Protective Equipment (PPE) as required per national and local regulations as well as for installation best practices. Ensure the electrical installation is in accordance with the National Electrical Code (NEC), ANSI, NFPA 70, all local electrical codes, and with the authority having jurisdiction. If there are any contradictions between the NEC and this document, follow the NEC requirements. Install, operate, and use this product in a manner consistent with the instructions provided. Failure to follow the procedures indicated may result in roof leaks, property damage, or consequential damage.
· Ensure all electrical conductors are at zero voltage potential before installing or servicing this unit. · Never break contact on a circuit without using the appropriate disconnect device. · Follow established lockout-tagout procedures for all electrical conductors prior to servicing. · Photovoltaic systems produce potentially lethal electrical energy when exposed to light. Use all appropriate procedures to de-ener
gize the photovoltaic system and the conductors leaving the system prior to service. · Ensure all wires are in good service condition. Nicked, pinched, or damaged wires can lead to electrocution or cause a fire. · Be aware of and work away from power lines. Contact with power lines could result in electrocution, personal injury, or death. · When disconnecting source or supply circuits, provide sufficient time as stated in the power electronics manufacturer’s instruction
manual in order to ensure discharge of all conductors in the circuit. · Always verify the integrity and proper installation of the electrical components prior to energizing electrical circuits. · Non-metallic enclosures do not provide grounding means between conduit connections if used. The use of grounding hubs and
jumper wires are required. · Grounding must be sized per NEC requirements and is the responsibility of the installer. · Wear safety equipment rated for a minimum of 600V or as required for the specific site conditions. · Disconnect all conductors form the array prior to making or breaking connections within this product or within any other point of the
circuit. · Activating the AC and/or DC disconnect switch within a circuit does not shut off potential electrical energy or voltage from the
photovoltaic panels. Ensure the photovoltaic array is disconnected and there is zero voltage potential on the conductors being installed before servicing this product. · Do not use this equipment in a manner other than that outlined in these instructions. Doing so may cause personal injury or death. · Check all wiring and connections for integrity and proper installation prior to energizing the circuit. · Always de-energize the DC and AC circuits prior to installation or service. Neglecting to do so could result in property damage, personal injury of death. · If any part of this product becomes damaged, remove and discard the entire unit, and replace with a new one. Failure to do so could result in fire, property damage, personal injury, electrocution, or death. · When disconnecting the inverter, allow 15 minutes for all electrical storage components to discharge before servicing any conduc tors in that circuit. · Do not install if the roof is wet, frosted, or covered by ice or snow. · Whenever drilling into an attic space, ensure that no electrical wires, conduit or electrical components are on the other side. Failure to note electrical equipment locations could lead to damage which could result in electrocution, personal injury or death. · Do not use the product to anchor fall protection equipment. · When determining ambient operating temperature, system designer must take into account external sources of heat such as irradiance from the sun or the environmental conditions under which the product is installed such as under a PV module. Exceeding the temperature rating could cause electrical failure or arching that could result in property damage, fire, electrocution, personal injury or death. · The installation of this product requires working on roofs. Follow applicable safety regulations and best practices to avoid falling from the work area. Take steps to prevent objects from falling off the roof. · Never work alone. Someone should always be in range of your voice or close enough to come to your aid in the event of an accident. · Remove all rings, bracelets, necklaces, watches or other metal equipment that could become energized while working with electrical conductors and equipment. · If modules are required to be removed or lifted during JB-1.XL servicing, ensure the system is designed such that the removal of the module will not disturb or break the system ground path. In addition, ensure the lifted module maintains its ground during servicing. Failure to follow these instructions could produce a shock hazard leading to personal injury or death. · Use a very sharp cutting tool to drill through the box walls and floor then clean all burs.
