User Manual Revision 2.5
Equipotential Referencing
Safety and compliance with standards in a medical environment is highly dependent on the
proper crafting of the electrical realm in which medical electrical equipment operates. All
devices should be referenced to an equipotential plane that spans the set of equipment and
devices used by the practitioners that may possibly come in contact with the patient and/or the
practitioner.
The ZyPer4K-M equipment
MUST be connected to the the
known and common
equipotential reference by
bonding the devices electrically.
This is achieved by connecting
the equipotential plane
reference to the unit via the
equipotential stud.
The ZyPer4K-M devices all have a universal stud on the rear of the unit near the power
connector for this purpose. Two nuts are also provided to allow for a “locking connection”. This
stud is sized and threaded for #8 hardware.
This is a reference point
that In order to insure the
voltage potential of the
enclosure of the ZyPer4K-M
unit is referenced to a
known common level.
It is the responsibility of the equipment installer to electrically connect this
point to the equipotential reference plane with a suitable type of contact and
wire. Running the equipment without this connection is outside the scope of
certified operation for the ZyPer4K-M equipment.
The grounding wire and crimped lug is NOT provided as part of the ZyPer4K-
M unit as that item is site-specific.
