In jurisdictions where the local utility requires that the AC disconnect be capable
of being locked in the open position by its service personnel, this disconnect
switch can also serve as a lockable isolating device.
Important:
In North America and other locations the wiring/disconnect box is an
electrical code requirement. Regulatory approval is based on the wiring/disconnect box
always being attached to the inverter during operation. Any attempt to remove this box
will invalidate the approvals and create an electrical hazard.
