1 • INSTALLATION
• Dimensions and cut-out: Panel mounting
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/CEE with reference to the generic Standard EN50082-2 (immunity in industrial
environments) and EN50081-1 (emission in residential environments). BT (low voltage)
conformity to Directive 73/23/CEE 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 instructions.
