If the computer and display module of the M1165/66/75/76A Systems and
the Anesthetic Gas Module are set up together, connect the grounding
wire to the equipotential grounding terminal on the display.
If the computer and display module of the M1165/66/75/76A Systems and
the Anesthetic Gas Module are separated, connect one grounding wire
to the display, one to the computer module and one to the Anesthetic
Gas Module.
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
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.
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 Warning
Do not use a 3-wire to 2-wire adapter with these instruments
If the computer and display module of the M1165/66/75/76A Systems and
the Anesthetic Gas Module are set up together, connect the grounding
wire to the equipotential grounding terminal on the display.
