SECTION 2: SAFETY & EMC INSTRUCTIONS DS2100 User's Manual
C27750-001 PAGE 2-5
2.2.1 System Safeguards
a) General Safety Requirements
Users are required to implement safety measures with all equipment, systems and installations into which the DS2100
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 DS2100 Series Controllers are installed.
The user is required to provide safety interlocks to prevent unexpected restart during servicing of the DS2100 Controller
and any equipment attached to or driven by these units.
The DS2100 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 DS2100
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
DS2100 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 0.1Ω.
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 DS2100 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.

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.
