Panel mounting:
Fix the device with the bracket provided before making any electrical
connections.
To mount two or more devices side by side, use the cut-out dimensions
shown above.
CE MARKING: EMC (electromagnetic compatibility) conformity to EEC
Directive 89/336/EEC with reference to the generic Standard CEI-
EN61000-6-2 (immunity in industrial environments) and EN50081-1
(emission in residential environments). BT (low voltage) conformity to
Directive 73/23/EEC as modified by Directive 93/68.
MAINTENANCE: Repairs must be done out only by trained and
specialized personnel. Cut power to the device before accessing
internal parts.
Do not clean the case with hydrocarbon-based solvents (Petrol,
Trichlorethylene, etc.). Use of these solvents can reduce the
mechanical reliability of the device. Use a cloth dampened in ethyl
alcohol or water to clean the external plastic case.
SERVICE: GEFRAN has a service department. The warranty excludes
defects caused by any use not conforming to these instruction.
EMC conformity has been tested with the following connections
