System Overview
ACQ-7700 / Type 3 Installation Manual
POWER SOURCE
This instrument is intended to operate indoors from a power source that does not apply more than 250 volts
RMS between the supply conductors or between either supply conductor and ground. A protective ground
connection by way of the grounding conductor in the power cord is required. If the unit is mounted in a
permanent installation (i.e. rack-mounted), then the user MUST provide access to the plug OR connect the
instrument to a circuit with a user accessible breaker or power switch. The detachable power cord is the means
by which the mains are disconnected.
PROPERLY GROUND THE INSTRUMENT
This instrument is grounded through the power cord. It is a Class 1 Device. Grounding reliability can only be
achieved when the equipment is connected to a hospital grade receptacle. Use only the power cord and
connector specified for your instrument. Use only a power cord that is in good condition.
Upon loss of the protective-ground connection, all accessible conductive parts (including knobs and controls
that may appear to be insulating) may render an electric shock.
USE PROPER TEST LEADS AND CABLES
Test leads and/or interconnect cables may carry
HAZARDOUS
live voltages. They must be examined regularly
for wear. Worn leads or cables should be replaced.
The amplifier has been designed and tested for protection against the effects of the discharge of a cardiac
defibrillator. For safe operation, use only the cables provided with the amplifier.
ECG ELECTRODE PLACEMENT
The user should assure that any electrodes used, including the neutral electrode, do not contact any conductive
parts, including earth.
Whenever a defibrillator is used, assure that the leads are placed on the appropriate places on the subject. Leads
should never be placed on grounded surfaces. Verify that defibrillator leads are NOT placed directly on the
ECG electrodes.
DO NOT USE WITH HF SURGICAL EQUIPMENT
It is imperative that the ECG electrodes be removed from the subject before using any HF surgical equipment.
This equipment DOES NOT provide protective means against burns when used with HF surgical equipment.
SUMMATION OF RISK CURRENT
The amplifier has been designed and tested to meet safe leakage current specifications when attached to the
subject. Any additional equipment added to the subject may increase leakage. The operator should be aware of
the possible summation of additional leakage currents when additional equipment is connected to the subject.
USE WITH PACEMAKERS
The operator should be aware of any possible interactions or safety hazards when the amplifier is used in
conjunction with cardiac pacemakers and other stimulant devices. The manufacturer of these devices should be
consulted for additional information.
