1 • INSTALLATION
• Dimensions and cut-out; panel mounting
Panel mounting:
To fix the unit, insert the brackets provided into the seats on either side of the
case. To mount two or more units side by side, respect the cut-out dimensions
shown in the drawing.
CE MARKING: EMC conformity (electromagnetic compatibility) with EEC Directive
89/336/CEE 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 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.
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 instructions.
