Device-specific safety instructions
ADVICE
As prerequisite for proper monitoring of the chassis ground connection (see chapter "Online self
test", page 14), terminal 31 must be connected to the same potential as LV-pin 3. This connection
may not be made directly at the device itself but via chassis ground. Only in this manner can it be
ensured that LV-pin 3 is also connected to chassis ground.
ADVICE
The ISOMETER® may not be connected to a CAN bus that is critical to safety.
ADVICE
In the event of an insulation fault in the monitored system the connection path of the device will get
hot. That behaviour is normal and must be taken into account when dismounting the device and
searching for faults, especially when ambient temperatures are high.
The internal flash memory guarantees up to 10.000 parameter changes over the entire service life of the
device.
