Safety Information
Introduction
The policy of Del Medical, Inc. is to manufacture X-ray equipment that
meet high standards of performance and reliability. We enforce strict
quality control techniques to eliminate the potential for defects and
hazards in our products.
The intended use of this equipment is to provide an adjustable elevating
platform for positioning of a patient with respect to an X-ray source for the
purpose of acquiring X-ray images of the desired parts of a patient’s
anatomy. Use of this equipment in any other fashion may lead to serious
personal injury.
The safety guidelines provided in this section of the manual are intended
to educate the operator on all safety issues in order to operate and
maintain the table in a safe manner.

EV800 Elevating Table Installation, Operation, & Service Manual
i-2 Statement of Liability
Statement of Liability
To prevent excess radiation exposure to the patient and the operator from
either primary or secondary radiation, this table must be operated and
serviced by trained personnel who are familiar with the safety precautions
required. While this table has been designed for safe operation, improper
operation or carelessness may result in serious injury or damage to
equipment. The manufacturer or its agents and representatives assume no
responsibility for the following:
1Injury or danger to any person from X-ray exposure.
2Overexposure due to poor technique selection.
3Injury or danger from improper use of the elevator function.
4Problems or hazards resulting from failure to maintain the equipment
as specified in the maintenance chapters.
5Equipment which has been tampered with or modified. Del Medical,
Inc. is not liable for any damage or injury arising from failure to
follow the instructions and procedures provided within the manuals
or associated informational material, or from user failure to use
caution when installing, operating, adjusting, or servicing this
equipment. Del Medical, Inc. is not liable for damage or injury arising
from the use of this product for any other use than that intended by
the manufacturer.

Definitions i-3
Definitions
The table below defines the meaning of various symbols found on device
labels on the machine.
This warning symbol indicates a potential hazard to
operators, service personnel or equipment. It indicates a
requirement to refer to the accompanying documentation for
details.
This symbol indicates that there is accessible dangerous
voltage.
This symbol identifies a protective earth terminal or ground.
This symbol states that this product is categorized as Type B.
Type B is defined as:
Equipment providing a particular degree of protection
against electric shock, particularly regarding allowable
leakage currents and reliability of the protective earth
connection (if present).
This symbol indicates that you must dispose of the EV800
Elevating Table properly according to local laws and
regulations. The EV800 contains electronic components;
therefore, it must be disposed of separately from household
waste. When the EV800 reaches its end of life, contact local
authorities to learn about disposal and recycling options.
The table has an estimated life of 10 years from point of
purchase. This may vary depending on (1) product use, (2)
product maintenance, and (3) environmental conditions.

i-6 Equipment Safety Guidelines
Equipment Safety Guidelines
The following warnings and cautions are specific to the EV800 Elevating
Table. Read them carefully - some of them are not obvious to typical
equipment use.
Warning
Turn off electrical power to the table at the power source before
servicing the table. Also, make sure that the power source is
locked out and tagged “Table Being Serviced” before servicing the
table; you could get seriously shocked or burned if you do not.
Warning
Do not place any objects within the vertical motion area above or
below table. Objects in such areas can present crush hazards for
the patient or operator and can also damage the table. See shaded
areas in figure below.
The table is equipped with a collision avoidance switch for
downward motion. This switch is designed to protect the table top,
not the operator or patient from a collision. The downward motion
of the table will stop if the table encounters 100 lbs (44kgs) of
upward force.

EV800 Elevating Table Installation, Operation, & Service Manual
Equipment Safety Guidelines i-7
Warning
Make sure the operator or the patient does not touch the table’s
unlock pedals when the patient is getting on or off table. This may
cause the patient to fall off the table and cause serious injury. See
figure below.
Warning
Do not operate the table in an explosive atmosphere (such as
anesthetic gas). Doing so can cause an explosion or a fire hazard
which could cause serious injury.

i-8 Equipment Safety Guidelines
Warning
All of the movable assemblies and parts of this equipment should
be operated with care and routinely inspected in accordance with
the manufacturer’s recommendations contained in this manual.
Only properly trained and qualified personnel should be
permitted access to any internal parts. Live electrical terminals are
deadly; be sure line disconnect switches are opened and other
appropriate precautions are taken before opening access doors,
removing enclosure panels, or attaching accessories.
Do not remove flexible high tension cables from X-ray tube
housing or high-tension generator and/or access covers from X-ray
generator until the main and auxiliary power supplies have been
disconnected.
For all components of the equipment, protective earthing means it
must be provided in compliance with the national regulations.
Warning
This table is intended to be used as part of a system for the
intended generation of X-rays for medical diagnosis.
X-rays generate a potential risk for both patients and operators.
For this reason, the application of X-rays for a given medical
purpose must aim at the minimization of radiation exposition to
any persons.
Those persons responsible for the application must have the
specific knowledge according to legal requirements and
regulations and must establish safe exposure procedures for this
kind of system.
Those persons responsible for the planning and installation of this
equipment must observe the national regulations.

Emergency Stop Button (For Service Technicians Only) i-9
Emergency Stop Button (For Service Technicians
Only)
There is an Emergency Stop button located in the table’s base that can be
pressed to stop the motion of the table in an emergency. It is meant only to
be used by technicians who are troubleshooting the table.
If the button is pressed, it must be turned in the direction of the arrows on
the button until the button pops back up in order to reset the button.
Otherwise, the table cannot be restarted. See Figure below for location of
button.
Warning
The Emergency Stop button DOES NOT turn off all power to the
table. There may still be lethal voltages present on the main
chassis and throughout the table when this button is turned off.
These voltages come from sources outside the table (i.e. generator,
wallstand, etc.) that are connected to the table.

i-10 Electrical Discharge (For Service Technicians Only)
Electrical Discharge (For Service Technicians Only)
This table’s main PCB contains capacitors that store energy after the
machine is turned off. You can be severely shocked if you work on the
table before these capacitors have completely discharged. The LED next to
the capacitors must be off before you can work on the machine. When the
LED is off, the capacitors have completely discharged.
Warning
Do not work on the table before the capacitor’s LED is off; you can
be severely shocked if you do.
Capacitor Discharge LED
LED must be off before servicing table.
