Warning PV Array DC Isolators Do Not De-Energise the PV Array

This warning label advises electricians and solar technicians that operating photovoltaic array DC isolators does not stop the PV array itself from generating electrical energy. It provides an important reminder that solar modules can remain a source of hazardous DC voltage whenever they are exposed to sufficient light.

Four size options

Available in 95mm x 38mm, 120mm x 30mm, 120mm x 50mm and 140mm x 30mm variants. This allows the warning to be matched to compact equipment, inverter areas and larger electrical enclosures while maintaining clear visibility.

DC isolation has a defined boundary

A DC isolator separates the sections of circuit it is designed to control. It does not make the modules incapable of producing voltage, and conductors on the array side of the isolation point can remain energised while sunlight is available.

Use with complete solar shutdown identification

Position the warning where personnel may rely on a DC isolator during shutdown or servicing. Clearly identify arrays, strings and isolation points and follow the installation-specific shutdown procedure, electrical drawings and equipment instructions.
