9 Anesthetic Gas Module Installation and Patient Safety
184
The Anesthetic Gas Module is protected against the effects of defibrillation and electrosurgery.
Power Supply Requirements
The system and the Anesthetic Gas Module can both be operated from an AC supply of 100 - 240V
±10%, 50 - 60Hz.
Grounding the System
To protect the patient and hospital personnel, the cabinet of the installed equipment has to be
grounded. The equipment is supplied with a detachable 3-wire cable which grounds the instrument to
the power line ground (protective earth) when plugged into an appropriate 3-wire receptacle. If a 3-
wire receptacle is not available, consult the hospital electrician.
WARNING Do not use a 3-wire to 2-wire adapter.
Equipotential Grounding
Protection class 1 instruments are already included in the protective grounding (protective earth)
system of the room by way of grounding contacts in the power plug. For internal examinations on the
heart or the brain, Computer Module and Display Module of the System and the Philips M1026A
Anesthetic Gas Module must have separate connections to the equipotential grounding system.
One end of the equipotential grounding cable (potential equalization conductor) is connected to the
equipotential grounding terminal on the instrument’s rear panel and the other end to one point of the
equipotential grounding system. The equipotential grounding system assumes the safety function of
the protective grounding conductor if ever there is a break in the protective grounding system.
Examinations in or on the heart (or brain) should only be carried out in rooms designed for medical
use incorporating an equipotential grounding system.
