● Heater:
To prevent condensation in the enclosure at low temperatures, it is recommendable to
install a heater. The heater must be dimensioned in accordance with the enclosure size.
A heater permits operation of the devices at temperatures below -20 °C.
Note
If components with a supply voltage of 120 / 230 V AC are installed, you must fuse these
devices according to DIN 41571 and/or IEC 60127 or in accordance with the manufacturer's
data.
● Modular electro-pneumatic automation system AirLine Ex (type 8650, from the company
Bürkert):
Connected to the ET 200iSP components to form an automation system for processing
electrical and pneumatic variables.
When connecting and operating, observe the manufacturer's descriptions and manuals.
● When installing a pneumatic system, exit the air passing through the exhaust connections
out of the enclosure.
NOTICE
Damage to seal or screwed glands
Make sure that the vent of the pneumatic system does not blow directly into the enclosure.
The pressure resulting in the enclosure would otherwise damage the seal and screwed
glands, and the degree of protection would no longer be provided.
