Compact / Series 7600 Installation Procedure 1

Introduction

This manual describes the installation of the Compact / Series 7600 system and a definition of the responsibilit ies and instructions for reporting, safety, unpacking, moving and verifying system operat ion.

Responsibility

The customer must provide the labor and equipment necessary to unload the system from the transport vehicle and move it to t he final location. It is the customer’s responsibility to obtain all permits necessar y to m eet all requirements of stat e and local codes, regulations and ordinances with respect to the installation and operation of the system.
A qualified service technician should perform the following:
• Installation Report/Checklist (00-879038-03).Safety procedures should be in effect at all times dur ing the installation process. By law, complete reports within 15 days from the date of assem bly (installation).
• Return the assembler's copy of the Report of Assembly of Diagnostic X-ray (FDA form 2579), the Beam Alignment Radiographs (films), and the Installation Report/Checklist t o O EC Medical Systems, Inc., Attention: Technical Support, in the stamped, manila envelope provided in the Field Service Documentation Package.
• Distribute the various remaining copies of the Report of Assem bly of Diagnostic X-ray (FDA form 2579) , following the documentation instructions included in the Field Service Documentation Package.
• The OEC Medical Systems, Inc. Representative MUST sign the last page of the Installation Report and Checklist, verifying Field Service acceptance of the unit. If, for any reason, the installation remains incomplete, notify the Hospital that the system is not yet ready for use.
NOTE

Safety Procedures

Under no circumstances should the safety interlocks in the system be bypassed, jumped or otherwise disabled. Never operate or store the system in a location where conductive fluids such as water, saline solution, etc., can spill on any part of the equipment unless you cover the system with a protective waterproof draping.
: All OEC Medical Systems, Inc. systems comply with International
Electrotechnical Commission safety standard IEC- 601. Do not connect any external device to the system that does not meet the req uir em ents of IEC-601. Only devices provided by or approved by OEC Medical Systems, Inc. should be connected to the system.

Explosion Hazard

Never operate the system in the presence of f lam m able anesthetics or other flammable or explosive liquids, vapors, or gases. Vapors and gases can ignite by electrical arcs that can occur during the normal operation of switches, circuit breakers, push-buttons and other cir cuit com ponents.

PROTECTIVE EARTH SMBOL PROTECTIVE EARTH STUD
WARNINGS:
Compact / Series 7600 Installation Procedure2
If flammable substances are pr esent before you apply system power, do not plug in or turn on the system.
If you detect flammable substances after the system has been turned on, do not touch any of the controls, switches, knobs or cables. Evacuate all per sonnel immediately, then ventilate the room to clear t he air of the flammable vapor or gas. Remove any volatile liquids that are producing flammable vapors to a safe storage area.
Electrical circuits inside the equipment use voltages that are capable of causing serious injury or death from electr ical shock.
This equipment contains high power elect ri cal components and only personnel familiar with the circuitry and its operation should provide service. Some components may maintain a charge with the power cord disconnected.
Observe safety precautions when measuring high voltage electronics. Steps within this procedure produce x- rays. Use appropriate precauti ons.
Areas where hazardous voltages exist include:
Transformers - 100 - 240 volts Video Monitors - 100 - 240 volts and High AC/DC Voltages Image Intensifier - 50,000 volts Generator - 110,00 volts
• Observe the following precautions when you remove system covers:
• Observe the two person rule when working near lethal voltages. A person
who is familiar with the emergency power removal procedure must be in attendance. This person must remain clear of the machine and be prepared to turn it off in an emergency.
• Be familiar with the components being serviced and the locations of hazardous voltages in the assembly where you work.
• High voltage cables and capacitors can retain a charge even when you remove all power from the system. Avoid touching these unless you are certain the charge has dissipated to gr ound.
• Some high energy capacitors in the system should be shorted to ground through an adequate resistance to avoid a burn hazard.
• A protective earth ground stud, located on the bottom left side of the system base, and marked with the international symbol shown below on the left. It also has a distinctly colored decal at t he base of the stud as shown below on the right.

Compact / Series 7600 Installation Procedure 3

Accident Reporting

The Medical Device Reporting Regulation, 21 CFR Part 803, r equires that the manufacturers of medical devices submit a report to the appropriate f ederal agency containing specific infor m ation in the event of an accident resulting in death or serious injury during the use or service of it s medical devices. (In the following paragraphs, labeling definitions include all instructional and procedural text contained in the Operator's Guide and Periodic Maintenance Procedures.)
A report is not necessary if:
•
The potential for death or t he type of serious injury that may result appears in the labeling for the system.
•
The malfunction and the rout ine ser vice, r epair , or maintenance in­structions to correct the problems appear in t he labeling for the system.
•
The malfunction has occurred at or below its expected rate of frequency and severity.
•
The malfunction does not lead the manufacturer to undertake a r em edial action involving any other systems.
For OEC Medical Systems, Inc. to meet these report ing r equirem ents, all users of these systems, operators, and service technicians, must provide the QA Manager of OEC Medical Systems, Inc. with the following information reg arding all reportable events as soon as possible:
1. Ident ify the model and the serial number.
2. Describe the event. I nclude whether any serious injury or death occurred, the number of personnel injured, and any publication tit le and dat es of any articles in the scientific or medical lit er at ure describing the reported event.
3. Identify the person who is submitting the information, include their address, to OEC Medical Systems, Inc.
4. Indicat e whether addit ional information will be submitted, and if so, when.
5. Indicate whether t he event being reported has occurred with greater frequency or severity than is indicated in the labeling for the system, or is unusual for this type of system.

Unauthorized Modifications

Unauthorized changes or modifications to any part of the system could have hazardous consequences. Changes or modifications are forbidden unless specifically authorized by OEC Medical Systems, Inc.

Line Voltage Compatibility Check

Check the line voltage in each room where the equipment operates. Do not assume the line voltage will be constant throughout the hospital.
Verify voltage compatibility in all hospital room s where this machine will operate. If a particular r oom is unavailable, write " NK" in the location, voltage and plug compatibility blanks on the checklist . A room is not plug compatible when the plug requires an adapter. Notify the hospital if any rooms are not voltage compatible.

Isolation Transformer Wiring

1. The isolat ion transformer(s) of the Compact / Series 7600 reside in the lower left portion of the gener ator cabinet. And in the lower rear section of the workstation (Series).
2. Direct ly above the generator isolation transformer and in t he lower rear of the workstation is the isolation transformer terminal block. The isolation transformer(s) have input taps for 90, 100, 110, and 120V.
3. Unplug the system from the wall receptacle and measure the AC voltage at the wall receptacle. Move the brown wire on the isolation transformer terminal blocks to the appropriat e input tap.

Power ON System

1. Plug the AC power cord into the system and then the wall receptacle (Compact).
2. Connect the interconnect cable between the generator and the workstat ion (Series).
3. Plug the AC power cord into the wall receptacle (Series).
4. Tur n the system on by pressing the green START butt on on the control panel (Compact / Series) or workstation (Ser ies) .
5. The system will display the OEC test pat tern on the monitors when the system has initialized.
