Warnings and Cautions
Chapter 2 Warnings and Cautions
WARNING
• The WM-DP1 mobile workstation should only be used in a medical
facility under the direction of a trained physician.
• Explosion hazard - never install or use the WM-DP1 mobile workstation
within the zone of risk of flammable gases. If the workstation is fitted
with antistatic castors (see Chapter 8), none of the medical electrical
equipment with which the workstation is intended to be used is ‘AP’ or
‘APG’ rated, therefore never install or use the WM-P1 series mobile
workstation within the zone of risk of flammable gases.
• To prevent patient shock, the combination of equipment used on the
WM-DP1 mobile workstation should never be applied directly to the
heart.
• If the fuse holder cap on the transformer is not fitted correctly, there is a
possibility that the fuse holder will overheat. When replacing the fuse,
ensure the fuse holder cap (Figure 4.3) is tightened using a 6mm to
8mm flat bladed screwdriver. The recommended tightening torque is
0.5Nm.
• Should the equipment become soiled with blood or other potentially
infectious materials, first wipe off all gross debris and then
decontaminate the equipment using a surface disinfectant, otherwise,
blood, mucus and other potentially infectious material from the patient
could pose an infection risk. Confirm that the equipment is completely
dry before use.
• Use personal protective equipment to guard against dangerous
chemicals and potentially infectious material, otherwise, blood, mucus
and other potentially infectious material from the patient could pose an
infection risk. During cleaning, wear appropriate protective equipment,
such as eye wear, face mask, moisture-resistant clothing and chemicalresistant gloves that fit properly and are long enough so that your skin is
not exposed.
• To prevent user or patient cross-contamination, do not hang
contaminated endoscopes on the scope hanger.
• The WM-DP1 should be used in accordance with the following.
Otherwise, the workstation will be ‘top heavy’ and may lose stability and
topple, causing equipment damage and/or personal injury.
- Two MAJ-181 restrictors are supplied which must be fitted to
MAJ-181 LCD monitor arm(s) if used (refer to section 4.8).
- LCD monitor arms and monitors should be installed after all
other equipment is installed on an appropriate place on the
workstation.
- LCD monitor arms should not be installed or used to the rear
of the workstation, see Figure 2.1.
- Confirm that the workstation does not lose stability when the
monitor arm is extended. If the workstation looks unstable,
relocate heavy equipment from the upper shelf to the bottom
shelf.

• Thoroughly review the manuals of all other equipment which will be
used. The manuals contain essential information on using this
equipment safely and effectively.
CAUTION
• Do not exceed the load capacity detailed in Chapter 8.
• Do not lean or stand on any part of the mobile workstation or accessory
as failure of the product may result.
• When assembling equipment onto the mobile workstation, the
installation should meet the requirements of EN IEC 60601-1-1:2001,
the safety standard for medical electrical systems.
• When configuring a system, the user should ensure that there is
sufficient spare equipment available that in the event of a fault in any
part of the system, the endoscopy procedure may be completed or
terminated without endangering the patient.
• Before commissioning an installation including a separation transformer,
ensure its rating will not be exceeded by the equipment connected to it.
• When installing the mobile workstation in the procedure or operating
room, ensure that the mains cable has sufficient slack that it cannot be
pulled taught as the mobile workstation is moved around the working
area. If necessary, relocate the mains connector to a nearer supply
socket.
Figure 2.1
• Section 6.2 Manoeuvring and Transportation gives detailed instructions
and precautions which must be read and understood before attempting
to move the mobile workstation.
MOBILE WORKSTATION WM-DP1
• Spray type medical agents, such as lubricants, anaesthetic or alcohol,
should be used away from the mobile workstation.
6
Warnings and Cautions
• Keep open containers of liquid away from electrical equipment used on
the mobile workstation to prevent operator electrical shock and
equipment damage. Do not use the system if liquid has entered the
equipment.
• To minimise risk of injury, it is recommended that heavy items are placed
on the mobile workstation by two people working together. This is
particularly important when placing a monitor on the optional monitor
platform (if fitted). Ensure electrical items used on the mobile
workstation are positioned centrally on the shelves.
• Never place any items on top of a monitor (if fitted) as these may topple
when the mobile workstation is moved.
• Where fitted, the electrical resistance of the conductive antistatic castors
should be tested at regular intervals in accordance with ISO 2878 to
assess antistatic effectiveness.
• Where antistatic castors are fitted, avoid contact of the castor wheels
with oil and avoid a build up of floor cleaning wax and polish as these
will impair the antistatic effectiveness of the castors.
• Store and use the WM-DP1 mobile workstation within the environmental
conditions described in Chapter 8; failure to do so may lead to
equipment malfunction or failure.
• There are no operator-serviceable components on the WM-DP1 mobile
workstation. Refer servicing to qualified service personnel.
• To minimise the risk of injury and/or damage, do not fit accessories other
than those described in Section 1.1 to the WM-DP1 mobile workstation.

Preparation for Use
Chapter 4 Preparation for Use
NOTE
• Multiple fixing positions are provided enabling the shelves to be raised
or lowered to accommodate varying equipment configurations (see 4.2).
• The mobile workstation is designed for use with Olympus OEV LCD
monitors and other monitors that meet the VESA standard. Contact
Olympus regarding compatibility of other monitors.
4.1 General information
Installation of endoscopic video systems requires an understanding of EN IEC 60601-1-1:2001,
the international collateral standard for the safety of medical electrical systems.
This standard requires systems to meet the leakage current requirements of the general medical
electrical safety standard, EN IEC 60601-1, which allows a maximum earth leakage current of
0.5mA in normal condition.
A separation transformer is required under certain circumstances, as combined earth leakage
currents may result in excessive enclosure leakage current under single fault conditions, such as
the interruption of a common protective earth path.
In order to meet EN IEC 60601-1-1:2001, a separation transformer will be required in a system
under one of the following conditions:
(i) Ancillary equipment that does not meet the leakage current requirements of
EN IEC 60601-1 is used (or could be used) within the ‘patient environment’ (as defined
in EN IEC 60601-1-1:2001, that is within a 1.5m radius of, or 2.5m above, the patient
bed). The separation transformer must be used to supply the ancillary equipment, but
may also be used to supply medical electrical equipment, as long as the maximum
transformer rating is not exceeded.
(ii) The total earth leakage current from a combination of medical equipment is above
0.5mA. The separation transformer must be used to supply sufficient of the medical
electrical equipment to reduce the total system earth leakage current to below the above
limit, as long as the maximum transformer rating is not exceeded. High intensity light
sources use arc lamps, which require a high start-up current. It is not recommended for
these to be supplied from the isolation transformer, otherwise its maximum rating may be
exceeded. The transformer may also be used to supply ancillary equipment forming part
of the system as long as the maximum transformer rating is not exceeded.
9
MOBILE WORKSTATION WM-DP1
Preparation for Use
Some system installations, for instance those using two mobile workstations, may require two
separation transformers to be fitted.
NOTE
• The total impedance of the protective earth path for a system may be up
Ω
to 0.4
or higher if the conditions of clause 18 g) of EN IEC 60601-1 are
satisfied.
• The power outlets should only be used for powering equipment which
forms part of the endoscopy imaging system.
• All equipment forming part of the system should be powered from the
transformer, unless appropriate isolation is employed as described in
Annex BBB of EN IEC 60601-1-1:2001. This particularly applies where
ancillary equipment as described in (i) forming part of the system is
remotely situated.
CAUTION
• Failure to observe either of the above mentioned points could result in
the isolation of the entire system being compromised, defeating the
protection provided by the transformer in a single fault condition.
Additional fixings are provided (Figure 4.1) to facilitate shelf adjustment or the fitting of the optional
drawer pack(s).
