This equipment (Class A, Group 1) is
designed and manufactured for use in
an industrial environment, in accordance
with EN 61000-6-2:2005 and EN 61000-6
4:2007 (with EN 55011:2007 limits). It is
not intended to be used on a low-voltage
public network which supplies domestic
premises. Radio frequency interference
may occur if it is used on a low voltage
public network.
This equipment equipped with VSD, may generate
conducted and radiated disturbances, which may inter-
fere with or damage susceptible connected apparatus.
Generally accepted engineering standards and practic-
es should be followed to ensure trouble-free and EMC
compliant electrical installation. Installations must
be supervised or completed by a competent person in
accordance with EN 13313.
Special considerations depending on the application:
• Industry standard grounding or “earthing” prac-
tices for the equipment and installation
• Use of shielded or special cables (power and/or
control)
• Use of metallic conduit and/or cable trays for
power and control cables connected to equipment
• Cable segregation (in order to avoid the risk of
crosstalk or cross interference to signal cables,
the power cables shall be segregated from signal
cables)
• Dedicated isolation transformer
•
Use of additional EMC filters
It is the responsibility of a designated System Integra-
tor to take proper steps assuring the Electromagnetic
Compatibility of both equipment and installation as a
system.
Rotating Parts
Fan guards must be fitted at all times and not removed
unless the power supply has been isolated. If ductwork
is to be fitted, requiring the wire fan guards to be re-
moved, alternative safety measures must be taken to
protect against the risk of injury from rotating fans.
Sharp Edges
The fins on the air-cooled condenser coils have sharp
metal edges. Reasonable care should be taken when
working in contact with the coils to avoid the risk of
minor abrasions and lacerations. The use of gloves is
recommended.
Frame rails, brakes, and other components may also
have sharp edges. Reasonable care should be taken
when working in contact with any components to avoid
risk of minor abrasions and lacerations.
Refrigerants and Oils
Refrigerants and oils used in the unit are generally non-
toxic, non-flammable and non-corrosive, and pose no
special safety hazards. Use of gloves and safety glass-
es is, however, recommended when working on the
unit. The buildup of refrigerant vapor, from a leak for
example, does pose a risk of asphyxiation in confined
or enclosed spaces and attention should be given to
good ventilation.
Use only the refrigerant specifically designated for the
unit. Any other type of refrigerant may cause damage
to the equipment and will void the warranty.
High Temperature and Pressure Cleaning
High temperature and pressure cleaning methods
(for example, steam cleaning) should not be used
on any part of the pressure system as this may cause
operation of the pressure relief device(s). Detergents
and solvents, which may cause corrosion, should also
be avoided.
