6�4 Connecting the grid heating mat
(1)
Pull the connection cable
provided for this purpose, which leads to
the thermostat
(2)
Check grid heating mat for continuity,
resistance and insulation value. Compare
the resistance value with the rating plate
of the mat and enter it in the test report
(see Appendix for test report). Deviations
from -5 % to +10 % of the nominal value
are permissible.
(3)
Attach the warning sticker to the electri-
cal distribution.
