SPECIFICATIONS AND PERFORMANCE
ELECTRIC RATING
Source voltage:100-240V AC, 50-60Hz
Power input:RM-8900:60VA KR-8900:75VA
SYSTEM CLASSIFICATION
Types of protection against electric shocks : This instrument is classified as Class 1 equipment.
Class 1 equipment dose not depend only on basic insulation for protection against electric shocks,
but also provides a means of connection to a protective earth system of facilities so that metal
parts that come into contact do not become conductive while the basic insulation is in failure.
Degree of protection against electric shocks : Type B applied part
Type B applied part is the applied part complying with the specified requirements of the Stan-
dard IEC 60601-1 to provide protection against electric shock, particularly regarding allowable
LEAKAGE CURRENT.
• Degree of protection against harmful ingress of water: IPX0
RM-8900 and KR-8900 has no protection against ingress of water. (The degree of protec-
tion against harmful ingress of water defined in IEC 60529 is IPX0)
• Classification according to the method(s) of sterilization or disinfection recommended by the
manufacturer: not applicable.
RM-8900 andKR-8900 has no part to be sterilized or be disinfected.
• Classification according to the degree of safety of application in the presence of a flamma-
ble anaesthetic mixture with air or with oxygen or nitrous oxide: Equipment not suitable for
use in the presence of a flammable anaesthetic mixture with air or with oxygen or nitrous
oxide.
RM-8900 and KR-8900 should be used in environments where no flammable anesthetics
and/or flammable gases are presents.
• Classification according to the mode of operation: Continuos operation.
Continuos operation is the operation under normal load for an unlimited period, without
the specified limits of temperature being exceeded.
