5. Installation, connection and commissioning
5.1 Installation
Install the device using four M5 screws, refer also to the dimension diagram.Install the device so that it is in a
vertical position with the system coupling (L1/+, L2/–) positioned at the top when it is being operated.
5.2 Connection
All enclosed plug-in terminals are labelled.
5.2.1 Connection requirements
Risk of electric shock!
Touching uninsulated live conductors can result in death or serious injury. Therefore avoid
any physical contact with active conductors and ensure compliance with the regulations for
working on electrical installations.
Warning of insulation monitoring devices that do not work correctly!
Connect the terminals KE and E individually to the protective earth conductor PE.
Risk of injury from sharp-edged terminals!
Risk of lacerations. Touch the enclosure and the terminals with due care.
Risk of property damage due to unprofessional installation!
If more than one insulation monitoring device is connected to a conductively connected
system, the system can be damaged. If several devices are connected, the device does not
function and does not signal insulation faults. Make sure that only one insulation monitoring
device is connected in each conductively connected system.
Ensure disconnection from the IT system!
When insulation or voltage tests are to be carried out, the device must be isolated from the
system for the test period. Otherwise the device may be damaged.
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.
