CE MARKING: EMC conformity (electromagnetic compatibility) with EEC Directive
89/336/CEE with reference to the generic Standard EN50082-2 (immunity in industrial
!
environments) and EN50081-1 (emission in residential environments). BT (low voltage)
conformity respecting the Directive 73/23/CEE modified by the Directive 93/68.
MAINTENANCE: Repairs must be done only by trained and specialized personnel. Cut
power to the device before accessing internal parts.
