The unit will take the same parameter readings even when the system recorded does not
have a neutral connection. The electrical parameters recorded by CIR-eQ when the unit
is connected to a single-phase circuit correspond to L1; all others are zero value.
In order to guarantee the unit's safe operation, all persons installing or
using the unit must follow the safety measures established in the current
low voltage safety regulations, as well as all warnings defined in this
instruction manual.
If you use the unit in a way that is not specified by the manufacturer, the
protection of the unit may be compromised and the user might be harmed.
Do not handle the air connector where the
terminals are connected to a voltage source.
We recommend use personal protective
equipment for handling and connecting the
device and follow the procedure explained in
this manual to avoid personal and equipment
injury.
