These precautions apply to installations made in Denmark.
Local requirements may differ.
Guldmann ceiling hoist and rail systems are manufactured
and installed in accordance with the rules on Electro-
Medical Equipment EN 60601-1.
Guldmann has a UL/DEMKO approval of its products
which confirms that they meet the requirements contained
in EN 60601-1.
This regulation defines how medical equipment must
be classified and also how it must be protected so that
danger of electric shock does not arise when handling the
products.
Guldmann ceiling hoist and related rail system are classi-
fied as equipment in Category II – High Voltage Regulation,
Electro-Medical Equipment, Chapter 14.
Reference is made to Fig. 701A – Area Division 0 to 3.
Installation of the rail system is carried out with safety
voltage – designated SELV. The safety transformer or safety
charger with a nominal voltage of 24 V AC voltage or
60 V DC voltage.
In accordance with the High Voltage Regulation,
Chapter 701 – AREAS WITH BATHTUBS OR SHOWERS
Chapter 701.4 Protection for safety reasons
When SELV is used (safety voltage), protection against
direct contact must be in place regardless of the size of
the voltage, i.e. to min IP2X.
The geometry of the live midi rails meet the requirements
for protection against contact.
Chapter 701.413.1.6 Additional equalizer
Note
Metallic pipes and ducts (Guldmann aluminium rails) which
are only found in these four areas and are not conductive
when in contact with earth or parts outside the areas do not
have to be connected to the equalizers.
Regarding installation of Guldmann rail systems
in bathroom environments
Guldmann power supply (charger and transformer) must
not be installed and charging of hoist must not be
carried out in Areas 0, 1 and 2. Power supply and charging
area must be located outside Area 2, but hoist and rails
may be used inside the area.
If e.g. cleaning by hosing, the power supply and charging
area must be located completely separate from the area in
which splashing with water may occur.
If the rail system is only installed in the bathroom and not
in other rooms outside the bathroom, the rails do not need
earthing.
Earthing must be done if the rails continue outside the
bathroom - connected by a single rail or a combi-lock and
the lower edge of the rail is less than 3.0 m (120”) above
the floor.
Excepted are:
Single rails hanging higher than 2.25 m (90”) above the
floor and not continuing into Area 0, 1 and 2.
Traverse rails hanging higher than 2.25 m (90”) above the
floor and not continuing into Area 0, 1 and 2 when it is
positioned in the Combi-lock.
For single rails the earthing may be located as required
either in the bathroom or in the adjacent room.
For Combi-locks the earthing on the single rail is located
outside the bathroom and when the traverse rail is
connected via the Combi-lock, the traverse rail is thereby
earthed in the bathroom.
The parallel rails do not need to be earthed.
Note
These rules have been issued by the Electricity Council
and form part of the High Voltage Regulation.
There may be special local requirements for the installation
of rail systems in medical treatment areas.
Any special requirements are carried out without the
participation of Guldmann at the purchaser’s own risk.
