CAUTION
Risk of property damage due to unprofessional installation!
If more than one insulation monitoring device is connected to a conductively
connected system, the system may be damaged. If several devices are
connected, the device does not work and does not signal insulation faults.
Make sure that only one insulation monitoring device is connected.
Heat on the enclosure surface!
The surface temperature of 60 °C can be exceeded under certain operating
conditions.
Keep the cooling slots uncovered by keeping a distance of at least 15 cm
above and at least 10 cm below the device to adjacent objects in order to
ensure constant air circulation.
Risk of injury from sharp-edged terminals!
Risk of lacerations. Touch the enclosure and the terminals with due care.
Only qualified personnel are permitted to carry out the work necessary to
install, commission and run a device or system.
DANGER
Risk of electrocution due to electric shock!
Touching live parts of the system carries the risk of:
• An electric shock
• Damage to the electrical installation
• Destruction of the device
Before installing and connecting the device, make sure that the
installation has been de-energised. Observe the rules for working on
electrical installations.
