v The grounding system must not carry current, such as
grounded neutral, since the current flow produces potential
differences along the ground path. These potential
differences are a shock hazard source for equipment users
and patients.
v Do not use conduit as a ground conductor. Plastic (PVC)
piping or fittings used in the conduit runs can break the
electrical connection to ground, resulting in potential shock
hazards.
v The electrical grounding system should be connected on an
earth ground. If this is not possible, then a good ground
reference such as a metal water pipe or an electrically-
conductive building component should be used. It is more
important that all grounded objects in the patient area are at
the same ground potential, rather than at earth ground
potential.
Equipment Installation
Installation of the AlarmView system consists of the following
steps.

Warnings
SHOCK HAZARD – A shock hazard may exist if external
devices are connected other than as described in this
manual, or as directed by the manufacturer.
Cautions
External equipment must be connected to the system only
by qualified biomedical engineering personnel. Only
external devices specifically designed to be connected to
the AlarmView system, approved by Data Critical for use
with the AlarmView system, should be connected, as
specified in this manual or as otherwise specified by the
manufacturer. All external cabling used with the
AlarmView system must be routed so as not to interfere
with access or operation of the system. All cabling must be
installed to protect against accidental disconnection of the
cables.
