double electrical insulation (Class II) and therefore they do not need an earth
connection.
The electrical installation must include a double pole switch with a contact clea-
rance of at least 3 mm.
The electrical cable must be introduced to the EDM through the slot (7) if the wire
is within the wall, or through the cable entry (2) if the installation is with a surface
mounted cable; in this case, the cable must be introduced as shown on Fig. 3b
and not as shown on Fig. 3a.
Once the cable has been introduced,

WARNING: The opening of the shutter is facilited by means of a thermal
system that needs some seconds to open completely.
EDM models H and CH
Models H and CH are provided with an electronic hygrostat which can be adjusted
from 60 to 90% RH (% relative humidity). They are
