Table 7.1: Temperature Sensor Inputs
The supported temperature sensor type is PT1000. For layout of the temperature sensor termi-
nal block, see the illustration
Auxiliary Connection Area
. For detailed specifications, refer to the
section
Auxiliary Interface Specifications
.
For setup, support, offset, adjustment and more, see the section on
Connection of Peripheral
Units
for instructions.
7.3.2. Irradiation Sensor
The irradiation measurement is read out via the display or Web Server and/or communication
(logging). The supported irradiation sensor type is passive with a max. output voltage of 150
mV.
For layout of the irradiation sensor terminal block, reference is made to the overview of Periph-
eral Units. For detailed specifications reference is made to the section
Auxiliary Interface Speci-
fications
. For setup, support, sensitivity, adjustment and more, see the section on
Connection of
Peripheral Units
for instructions.
7.3.3. Energy Meter Sensor (S0)
The energy meter input is read out via the display or Web Server and communication (logging).
The supported energy meter is supported according to EN62053-31 Annex D. S0 is a logical
count input.
To change the S0 calibration parameter, first enter the new setting, then restart the inverter to
activate the change.
For layout of the S0 terminal block, see the illustration
Auxiliary Connection Area
. For detailed
specifications reference is made to the section
Auxiliary Interface Specifications
. For setup, sup-
port, pulses per kWh and more, see the section
Connection of Peripheral Units
for instructions.
7.4.
Alarm Output
One alarm output is provided as potential free contacts Type NO (Normally Open). For setup,
activation and deactivation, refer to the section
Connection of Peripheral Units
.
7.5.
GSM Modem
An optional GSM modem is offered to monitor production data from the inverter via a data
warehouse service. The GSM option is ordered as a GPRS kit for later installation.
