2.2 General Safety Instructions

WARNING:
Please don't connect PV array positive(+) or negative(-) to ground, it could
cause serious damage to the inverter.
WARNING:
Electrical installations must be done in accordance with the local and national
electrical safety standards.
WARNING:
To reduce the risk of fire, over-current protective devices (OCPD) are
required for circuits connected to the inverter.
The DC OCPD shall be installed per local requirements. All photovoltaic
source and output circuit conductors shall have disconnects that comply
with the NEC Article 690, Part II. All Canadian Solar three phase inverters
feature an integrated DC switch.
CAUTION:
Risk of electric shock. Do not remove the frontal cover of the inverter.
There is no user serviceable parts inside.
Refer servicing to qualified and accredited service technicians.

2. Safety Instructions
CAUTION:
The PV array (solar panels) supplies a DC voltage when they are exposed to
sunlight, regardless if they are connected or not to an inverter.
CAUTION:
Risk of electric shock from energy stored in capacitors of the inverter.
After disconnecting all power sources, do NOT remove the frontal cover
of the inverter after at least 15 minutes.
Warranty may be voided if the cover is removed without explicit authorization.
CAUTION:
The surface temperature of the inverter can exceed 75℃ (167F).
To avoid risk of burns, DO NOT touch the surface of the inverter under
operation.
The inverter must be installed out of reach of children.
