Electrical installations
Protection against electric shock
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 regulations of Medical
Electrical Equipment IEC/UL 60601-1 .
Guldmann has a UL/DEMKO approval of its products
which confirms that they meet the requirements contained
in IEC/UL 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 transformer for fixed installed rail system is clas-
sified as equipment in Class I – High Voltage Regulation,
Medical Electrical Equipment .
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
with a nominal voltage of 33 V AC 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 rails meets the requirements for
protection against contact .
Regarding installation of Guldmann rail systems
in bathroom environments
Guldmann power supply (transformer) and rail with
charging liner must be installed in accordance with
the illustrations in Fig . 701A & 701B and guidelines
interpreted here below .
Guideline for transformer:
• Transformer class 1 must be installed above 3 m
(9
3
/
4
') if installed directly over areas 2 and 3 .
Or above 2,25 m (7
1
/
4
') if not installed directly above
areas 2 and 3 (outside area 3)
• Transformer class 2 must be installed above 2,25 m
(7
1
/
4
') (area 3) if the mains power is protected by a
residual-current circuit breaker max . 30 mA (RCCB)
(HPFI-breaker “DK”) .
Guidelines for single rail and room covering rail system:
• Single rail system without charging liner must be
installed above 2,25 m (7
1
/
4
'), ground connection of rail
(area 3 and outside area 3)
Guidelines for rail system with open end:
• The rail with charging liner must be installed with end
cover and with a minimum clearance of 100 mm (4") .
to the charging liner from the open rail end . (to apply to
IP20) .
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 .
For single rails the grounding may be located as required
either in the bathroom or in the adjacent room .
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 carried out without the partici-
pation of Guldmann are at the purchaser’s own risk .
