CAUTION!
Transmission errors and
damage to property due
to electrical faults
If the line is longer than 30 m, there
is an increased probability of transmission
errors and damage to the device due
to atmospheric discharge.
Use a shielded cable to connect
to the temperature sensor.

CAUTION!
Risk of injury due
to electric voltage!
Insuffi cient insulation of the operating
equipment at the temperature measurement
input to the mains supply circuits can cause
the temperature measurement input
and interfaces RS232 and RS485 to
be hazardous to touch.
Ensure that there is reinforced or double
insulation to the mains supply circuits!

WARNING!
Risk of injury due
to electric voltage!
RS232, RS485 and the temperature
measurement input are not galvanically
separated from each other.
Therefore, be aware that hazardous
voltages on the inputs that are not
galvanically separated may have effects
on the other connections.
