cord) for safe operation. For the safety of operating personnel and optimum
performance make sure that the instrument is only connected to a 3-prong socket
(outlet) that has an effective earth connection. If you are in any doubt about the safety
of your electrical supply system consult a competent, qualified electrician.
There are no user replaceable parts within the instrument. Do not remove the rear
cover from the 248.
Siemens Healthcare Diagnostics and its authorized Distributors and Agents consider
themselves responsible for the effects of safety, reliability and performance of the 248
only if:
The 248 pH/Blood Gas Analyzer is classed as IEC Type B equipment (Class 1
equipment providing an adequate degree of protection against electric shocks
particularly regarding allowable leakage currents and reliability of the protective
earth connection).
The 248 is designed for continuous operation and should be connected to the power
supply at all times, so that it is always ready for use.
The analyzer complies with IEC 601 for electrical and operating safety. It was not
designed for use in an environment containing a flammable anaesthetic mixture with
air, oxygen or nitrous oxide and is not designed to give protection against the ingress
of liquids.
The 248 is listed by Underwriters Laboratories as meeting the requirements
of the following Standards for Safety.
