3 Important Safety Instructions
SAVE THESE INSTRUCTIONS–This manual contains important instructions for
use with the AID that shall be followed during installation and maintenance of these
devices.
Installation of this equipment must be performed by an authorized electrician in
accordance with the local and NEC ANSI/NFPA 70 and OSHA requirements.
1. Before installing and using the AID, read all instructions presented in this manual and the
cautionary markings shown on the AID's enclosure.
2. During operation, hazardous voltages and currents may be present. Only authorized and
qualified personnel should perform servicing/installation.
3. Exposed PV strings to sunlight represent a shock hazard at the PV wires and exposed
terminals. Test any terminal for voltage before touching them. Check if any current is flowing
through the strings before removing connectors.
4. Only use accessories recommended or approved by the manufacturer.
5. Ensure that wiring is in good conditions and that all wiring is sized according to NEC 310-16
specifications.
6. PV modules produce electrical energy when exposed to light and thus can create an electrical
shock hazard. Wiring of the PV modules should only be performed by qualified personnel.
7. Always have AID manual on hand, for reference.
