Safeguards
a) Gen

ral Safety Requirements
Users are required to implement safety measures with all equipment, systems and installations into which the
DS2110 Servo-drive are installed. In addition, safeguards must be an integral part of workcell design, installation,
operator training and operator procedures where this equipment is used.
b) Specific Safety Requirements
The specific safety measures described below are required to be installed by the user into all equipment, systems
and installations into which the DS2110 Series Controllers are installed.
The user is required to provide safety interlocks to prevent unexpected restart during servicing of the DS2110
Controller and any equipment attached to or driven by these units.
The DS2110 Servo-drives themselves must be installed in enclosures or cabinets that provide a degree of ingress
protection against liquids and objects of at least IP54. These enclosures or cabinets must be accessible to
technically qualified service or maintenance persons only. All external Regen (Regenerative circuit) resistors used
with the DS2110 must be installed in enclosures which provide a degree of ingress protection against liquids and
objects of at least IP22 and which are accessible to technically qualified service or maintenance persons only.
Protection against electric shock must be maintained when installing these resistors.
The equipment may have a continuous leakage current of more than 3.5 mA A.C. or 10 mA D.C. in normal use.
The DS2110 must be permanently and reliably connected to Earth and all conductive parts in the IP54 rated
enclosure or cabinet must be permanently connected to Earth. The impedance between the earth terminal and
any accessible part of the enclosure or cabinet should be less than or equal to 0.1ohm.
A D.C component can occur in the fault current in the event of a fault connection to earth. Only a residual-current-
operated protective device (RCD) of Type B is allowed. When the protection in installations with regard to indirect
contact is achieved by means of an RCD, their appropriate function/combination shall be verified.
All electrical supply wires and cables to this equipment must be installed in wireways (cable routings) which are
smooth and free from sharp edges.
Users are directed to refer to the European Union (EU) Machine Safety
Directive: 98/37/EC and EU Low Voltage Directive 73/23/EEC (as amended by
EU Directive 93/68/EEC) for essential health and safety requirements to be
met. Furthermore the requirements of the EU EMC Directive: 89/336/EEC (as
amended by EU Directive 92/31/EEC and 93/68/EEC) must be met by all
equipment, systems and installations into which the DS2110 Controllers are
installed.
Users are recommended to refer to the latest publications of the European
Union (EU) Commission and to local regulations for further information on the
requirements of these Directives of the
EU.

Required for
CE-Compliance
Users are required to ensure that the drive is only connected to supply network
configurations of the following types
•
TN Systems including TN-C, TN-S, TN-C-S
•
TT Systems.
Connection to IT systems or corner-earthed TN systems is not allowed. Users
should ensure the nature of the supply system is appropriate before connecting
and operating the drive.
