Gauge identification
WARNING: HIGH VOLTAGE
Risk of electrical shock. The gauge can only be connected to power supplies, instruments
or control devices that comply with the requirements of a grounded Protective Extra-Low
Voltage (PELV) and Limited Power Source (LPS), Class 2. The connection to the gauge has
to be fused.
*
Edwards controllers meet this requirement.
