1.6 Service Manual CNS-9701
1. GENERAL
Installation
WARNING
Install the central monitor and external instruments outside the
patient environment (IEC 60601-1-1 2.204). If they are installed inside
the patient environment, the patient or operator may receive
electrical shock. For installation, contact your Nihon Kohden
distributor or representative.
CAUTION
••
••
• Only use the provided power cord. Using other power cords may
result in electrical shock or other injury to the patient and operator.
••
••
• Before connecting or disconnecting instruments, turn each
instrument off and disconnect each power cord from the AC socket.
Failure to follow this caution may cause electrical shock.
••
••
• Connect only the specified instruments to the central monitor by
following the specified procedure. Otherwise, electrical leakage
current may harm the patient and operator.
••
••
• Do not let connection cables stick out; run them along the floor or
wall. If people trip over the cable, the monitor may tip over and it
may cause injury.
UPS
WARNING
••
••
• Install the UPS outside the patient environment (IEC 60601-1-1 2.204).
If it is installed inside the patient environment, the safety standards
which are required by Nihon Kohden are not satisfied and it may
cause electrical shock to the patient or operator.
••
••
• Use a UPS which satisfies the safety standards specified by IEC and
UL. Otherwise, lack of safety may cause electrical shock to the
patient or operator.
••
••
• Periodically check the life of the UPS battery. Replace the battery
when the lifetime expires. If the battery is used beyond its lifetime,
liquid leakage, smoke, fire or explosion may occur.
CAUTION
••
••
• Make sure that the UPS is properly grounded. Otherwise the
operator may receive electrical shock.
••
••
• To assure an uninterrupted power supply, we recommend using the
specified UPS. A sudden loss of power supply or an extreme power
surge can damage the central monitor and delete stored data.
