Are the devices interchangeable?
HE can be replaced with HD easily, taking the ins-
tallation conditions into account.
External activation of the HE must be adapted to the
internal drive-based control of the HD!
HD can only be replaced with HE after careful ins-
pection, possibly by external service providers.
Additional equipment is necessary.
Check the installation conditions!

der, etc. standard?
