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: The instrument conforms to the European Directives 2004/108/CE and
2006/95/CE with reference to the generic standards:
EN 61000-6-2 (immunity in industrial
environment)
EN 61000-6-3 (emission in residential environment) EN 61010-1 (safety).
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.
