for communication links. The connections are described below:
A. Digital outputs. Optional. The digital outputs are relays, which can be used for alarms and
for controlling other equipment. The meter can also be programmed to activate the digital
outputs under certain conditions, for example when a transient of a certain level is recorded.
The digital outputs are configured using the PQ Online program.
Digital inputs. Optional. The digital inputs are galvanically isolated with a common for each
