1.2.2. ENVIRONMENTAL CONDITIONS

The equipment is to be installed in rooms that satisfy the following requirements:
-
Temperature from +10 to +40°C.
-
Relative humidity from 25 to 75% without condensate.
-
Atmospheric pressure from 700 to 1060 hPa.
-
The electrical wiring in the room in which the equipment is installed must conform to I.E.C. 60364-7-710;V2
specification (i.e. the regulations concerning the electrical wiring to be used in surgeries) or equivalent standards
in force in the country where the equipment is installed.
-
ELECTRICAL CONNECTIONS: The electrical wiring must have an effective ground conductor as set forth by
I.E.C. -US National Electrical Codes and C.E.I. standards. In Italy, electrical wiring must comply to standards IEC
60364-7-710 which require that a ground fault circuit interrupter is installed upstream.The ground fault circuit
interrupter must be as specified below:
-
contact capacity: 250V 10A in compliance with standards IEC 60898-1 and IEC 60947-2;
-
differential sensitivity: 0.03A;
-
power supply: 3x2.5 mm
The color of the 3 wires should be as specified in the standards (brown power, BLUE neutral, YELLOW/GREEN
ground).
-
POWER SUPPLY CUT OFF (INCORPORATED x-ray unit version):
A two-pole switch has to be installed in a position that can be easily reached by the operator in order to shut off
electrical power separately from the dental unit. The contacts of the two-pole switch, that may be used as a sole
device with differential-magnetothermal functions, should be at least 3 mm apart (as set forth in standard IEC
60601-1). In addition, it should have a 250V 10 A contact capacity and comply to standards IEC 61058-1 and IEC
60447. The ON position must be clearly indicated.
