Perform all electrical installations in accordance with all local electrical codes.
Comply the rules of correctly use of tools and personal protective equipment (PPE)
for insuring the Micro-Inverter safe running.
Even if the inverter is not in running condition, the power input and output lines may
still be charged with a hazardous voltage. After breaking the circuit and waiting for
more than 45 minutes to ensure the inverter discharged to a safe low-voltage, and
then start the installation.
Be aware that only qualified personnel should maintain INVOLAR Micro-Inverter.
Connect the INVOLAR Micro-Inverter to the electrical utility grid only after receiving prior
approval from the utility company.
In the day time, Use opaque covering on PV array to screen the sunshine before
installing the INVOLAR Micro-Inverter, thus eliminating the risk of personnel
exposure to lethal high-voltage.
The photovoltaic micro-inverter is not intended to be secured to the back of the
photovoltaic module. It should be secured to the framework supporting the PV module.
MAC250 is intended to be connected only to a dedicated branch circuit.
The device is not provided with ground-fault detector/interrupter unit.
WARNINGS
Always Disconnect the unit from the MAINS and PV supply by the
external customer installed disconnecting devices before installation,
servicing and maintenance works, and placed a warning sign adjacent
to switch “do not turn on maintenance in progress”.
WARNINGS
PV arrays are energized when exposed to light, they are supply a D.C.
voltage to the inverter. Use safe working practices when working on
PV arrays.
