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 chemical-
resistant 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.

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.

Preparation for Use
MOBILE WORKSTATION WM-DP1 10
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
to 0.4
Ω 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).

4.3 Remote switch
The remote switch enables the power to the system components to be controlled from a
single point. The switch is located beneath the top tray and connects to the remote switch
connector on the separation transformer via a 2m cable.
The remote switch has an integral two-colour LED which illuminates whenever the
transformer is connected to the mains supply. Yellow indicates ‘standby’, green indicates
‘output on’.
NOTE
• The remote switch only controls the output socket on the transformer. To
switch OFF the input power supply, set the remote switch to its
‘stand-by’ position, then disconnect the mains connector from the wall
outlet socket.
• In ‘stand-by’ condition, the transformer consumes a small amount of
power, typically 4% of its full load rating. If it is anticipated that the
system will not be used for a significant period of time, it is
recommended that the mains connector is removed from the wall outlet
socket to conserve energy.
1. The mobile workstation is supplied with the remote switch connected to the separation
transformer and no assembly is required. However, check the connection (see Figure 4.3) is
secure before completing full installation.
