Resistors
Resistors prevent condensation, corrosion and superficial leakage currents.They
maintain a positive temperature in the enclosures and cubicles when external
temperatures drop very low.
bb
Install heaters according to the desired power level at the bottom of the enclosure
bb
Respect a safety area of a least 10 cm around the device
bb
The heaters must be installed with a thermal controller to control the temperature
or the humidity inside the enclosure.
bb
The enclosure must be sealed to prevent the entry of air from the outside.
bb
An electrical protection device must be installed on the supply side of the unit.
bb
Surface temperature limited to 75 °C when the ambient temperature is -5 °C.
bb
Heaters equipped with a power cable with a length of 500 mm with silicon
insulation, or with a connection terminal block.
