Installing the Potential Equalization Pin in CardioSys /
MicroLab Systems
When operating the printer "HP Laser Jet 6P" in the patient environment in conjunction with
CardioSys / MicroLab (1.5 m/5 ft.), an authorized service technician is required to install
the potential equalization pin as described below.
Installation:
1. Unscrew the potential equalization cable "PE" from CardioSys / MicroLab (see
illustration) and pull out a length of cable that is sufficient to connect it to the
printer. (Caution: You will need the screw and washer later when connecting
the cable.)
(For older CardioSys systems (without potential equalization cable for the
printer) it is recommended to provide a separate potential equalization cable in
paralled with the printer power cord and to conect it to ground (GND).
