3. INVERTER SAFETY
3.1 SAFETY INSTRUCTIONS
International safety regulations have been strictly observed in the design and testing of the inverter.
Before beginning any work, carefully read all safety instructions, and always observe them when
working on or with the inverter. The installation must follow all applicable national or local standards
and regulations.
Incorrect installation may cause:
• Injury or death to the installer, operator or third party
• Damage to the inverter or other attached equipment
3.2 IMPORTANT SAFETY NOTIFICATIONS
Hazardous Voltage Circuits!
AVERTISSEMENT! Circuits à tension élevée!
There are various safety concerns that must be carefully observed before, during,
and after the installation, as well as during future operation and maintenance. The
following are important safety notifications for the installer and any end users of this
product under normal operating conditions.
1. Beware of high PV voltage. Install an external DC disconnect switch or breaker and ensure
it is in the “off” or “open” position before installing or working on the inverter. Use a voltmeter
to confirm there is no DC voltage present to avoid electric shock.
2. Beware of high grid voltage. Ensure the AC switch and/or AC breaker are in the “off” or
“open” position before installing or working on the inverter. Use a voltmeter to confirm there is
no voltage present to avoid electric shock.
3. Beware of high battery current. Ensure that the battery module breakers and/or on/off
switches are in the “open” or “off” position before installing or working on the inverter. Use a
voltmeter to confirm there is no DC voltage present to avoid electric shock.
4. Do not open the inverter while it is operating to avoid electric shock and damage from
live voltage and current within the system.
5. Do not make any connections or disconnections (PV, battery, grid, communication, etc.) while
the inverter is operating.
6. An installer should make sure to be well protected by reasonable and professional insulative
equipment [e.g., personal protective equipment (PPE)].
7. Before installing, operating, or maintaining the system, it is important to inspect all existing
wiring to ensure that it meets the appropriate specifications and conditions for use.
8. Ensure that the PV, battery, and grid connections to the inverter are secure and proper to
prevent damage or injuries caused by improper installation.
9. Some components of the system can be very heavy. Be sure to utilize team lift and other
safe lifting techniques throughout the installation.
