Precautions when connecting the
electrical wiring
INFORMATION
Also read the precautions and requirements in the
following chapters:
▪ General safety precautions
▪ Preparation
DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
CAUTION
For use of units in applications with temperature alarm
settings it is recommended to foresee a delay of 10
minutes for signalling the alarm in case the alarm
temperature is exceeded. The unit may stop for several
minutes during normal operation for "defrosting the unit", or
when in "thermostat stop" operation.
6.7.4
Guidelines when connecting the electrical
wiring
Keep the following in mind:
▪ If stranded conductor wires are being used, install a round crimp-
style terminal on the tip. Place the round crimp-style terminal on
the wire up to the covered part and fasten the terminal with the
appropriate tool.
