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.
