5.1 Installation of the isoPV
Check proper connection!
Prior to commissioning of the installation, check that the device has been
properly connected and check the device functions. Perform a functional
test using an earth fault via a suitable resistance.
Prevent measurement errors!
When the AC system being monitored contains galvanically coupled DC
circuits, take into consideration that: an insulation fault can only be
detected correctly when the rectifier valves carry a minimum current of >
10 mA.
For UL applications:
Only use 60/75°C copper lines!
For UL and CSA applications, the supply voltage must be protected via
5-A fuses.
In order to ensure compliance with prescribed temperature limit values,
install the isoPV and AGH-PV with a distance of at least 31 mm to all
adjacent devices!
The cable length of the connecting cables between the AGH-PV and isoPV
must not exceed 0.5 m.
For UL-Applications :
High Voltage Coupler AGH-PV should be mounted min. 30.8 mm away
from the walls of a metal enclosure and uninsulated grounded parts and
uninsulated live parts.
Use 60 °C/75 °C copper conductors only!
Tightening torque:
isoPV: 0.6 Nm…0.8 Nm, AGH-PV: 0.5 Nm
