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 MARKINGThe 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)

.

MAINTENANCERepairs 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.
SERVICEGEFRAN has a service department. The warranty excludes 
defects caused by any use not conforming to these instructions.
