Chapter 4 - Installation; Connection; Connection Of The Mains Adapter; Switching On And Self Test - Enraf Nonius Sonopuls 492 Instrucciones De Manejo

4.1. Connection

• Mains supply connections must comply with the
national requirements regarding medical rooms.
The equipment has a safety earth (ground) con-
nection, and must be connected to an earthed
(grounded) wall socket.
• Prior to connection of this apparatus to the mains
supply, check that the voltage and frequency
stated on the type plate correspond with the avail-
able mains supply.
• The mains adapter is a part of the supply circuit on
which the device's safety partly depends. The ap-
provals for the Sonopuls 492 are only valid if used
in combination with this type of adapter ENA 1550.
It is not permitted to connect the Sonopuls 492
to another type of adapter than type ENA-1550.

4.2. Connection of the mains adapter

• Connect the supplied mains adapter to the con-
nector [3-1].
• Connect the mains adapter to a wall socket. Lamp
[6] indicates that the apparatus is connected to
the mains supply and stand-by.

4.3. Switching on and self test

• Switch On the apparatus, using the On/Off switch [1]
• Immediately after switching on, the apparatus car-
ries out a self test.
At the end of the self-test a beep is heard. When an
error is found an error code will appear on the dis-
play. See section 7 for details.

4.4. Disconnecting from the mains

• Switch Off the Sonopuls 492, using the On/Off
switch [1].
• Pull out the mains plug of the mains adapter from
the wall socket.

4.5. Battery operation (optional)

The apparatus can be operated independent of the
mains supply. To make this possible, first a battery
must be installed. This is done as follows:
• Turn off the apparatus and remove the mains adapter
from connector [3-1].
• Put the apparatus upside down and remove the two
screws fixating the battery compartment cover to the
bottom of the apparatus.
• Connect the red lead to the positive (+) pole of the
battery and the black lead to the negative (–) pole.
• Slide the battery into its compartment.
• Reattach the battery compartment cover using the
32
two screws.
• Reconnect the mains adapter to connector [3-1].

CHAPTER 4 - INSTALLATION

With a mains adapter connected, the battery is auto-
matically charged, independent of the state of the on/
off switch [1]. We recommend to use the apparatus
with the mains adapter connected whenever possible.
This will increase the service life of the battery.
We recommend to explicitly use Enraf-Nonius sup-
plied batteries of type 2601.016. The battery con-
tains material that is noxious to the environment. You
should attend the local regulations when disposing
the battery. See also chapter 6.4.

4.6. Installation

• Do not install the apparatus in a location near a
heat source such as a radiator.
• Avoid exposure to direct sunlight, rain, excessive
dust, moisture, mechanical vibrations and shocks.
• Cordless telephones should not be used in close
proximity of the apparatus.
• This apparatus should not be used in so-called
"wet- rooms" (hydrotherapy rooms).
• The apparatus has to be installed in such way
that liquid cannot enter.
• It is not permitted to connect the Sonopuls 492
to another type of adapter than type ENA-1550.
Should any liquid ingress into the housing of this
equipment, unplug the apparatus from the wall
socket (if connected) and have it checked by an
authorised expert.
Connection of accessories other than ones
specified by the manufacturer can adversely
affect the safety of the patient and correct
functioning of the equipment, and is there-
fore not permitted.

4.7. Electromagnetic interference

• Operation in close proximity (i.e. less than 2
metres) to working shortwave or microwave
therapy units may produce instability in the
Sonopuls 492 output.
• To prevent electromagnetic interference, we
strongly advise using separate mains groups
(phases) for the Sonopuls 492 and the shortwave
or microwave equipment, and a distance of at
least 2 metres is kept between the Sonopuls 492
and the shortwave or microwave equipment.
• Ensure that the mains cable of the shortwave/mi-
crowave unit does not come near the Sonopuls
492 or the patient.
If problems with electromagnetic interference per-
sist, please contact your authorised distributor.
