General versions for horizontal and vertical applications are
available.
The Design Guide provides the information required to
select and plan installation of the right brake resistor for
an application:
•
Selection of the correct brake resistor
•
Pre-installation considerations
•
Programming.
As an alternative to using a brake resistor, other braking
methods can be applied depending on the braking profile
of the application, see chapter 7 Special Conditions.

1.2 Conformity

Table 1.1 Approval
1) See Table 9.2 and Table 9.4 for UL conformity.
What is CE Conformity and Labelling
The purpose of CE labelling is to avoid technical trade
obstacles within EFTA and the EU. The EU has introduced
the CE label as a simple way of showing whether a
product complies with the relevant EU directives. The CE
label says nothing about the specifications or quality of
the product. Brake resistors are regulated by the following
EU directive:
The low-voltage directive (2006/95/EC)
Brake resistors must be CE labelled in accordance with the
low-voltage directive of December 12, 2006. The directive
applies to all electrical equipment and appliances used in
the 50-1000 V AC and the 75-1500 V DC voltage ranges.
Danfoss CE-labels in accordance with the directive and
issues a declaration of conformity upon request.

1.3 Safety Precautions

WARNING
When in use, the brake resistor surface temperature
rises. DO NOT touch the brake resistor during operation.
WARNING
Never work on a brake resistor in operation.
NOTICE
Never attempt to repair a defective brake resistor.

1.4 Disposal

Equipment containing electrical components
may not be disposed of together with
domestic waste.
It must be separately collected with electrical
and electronic waste according to local and
currently valid legislation.
