Guide Lines For Eu Installations - KEP MMI-1500 Installation & Operation Manual

The MMI Series has been designed to operate satisfactorily in electromagnetic noise (immunity) and without emitting high
levels of electrical noise into the environment (emission). The units are designed to meet European Community standards
when installed per the wiring instructions in this manual.
Compatibility Standards
The MMI has been designed to meet electromagnetic compatibility for industrial environments.
Standard
CISPR (EN 55011) Group 1, Class A
EN50081-2
EN50082-2

2.3.2 Guide Lines for EU Installations

• Be aware that wiring leaving the cabinet where the unit is installed may be exposed to interference sources.
• The installation practices in the individual product installation manuals of other components in the system must also be
followed.
• Locally applicable grounding safety regulations and machinery directives should be followed for providing a protective
ground to earth. The EMC ground must be a low impedance, low inductance path to the machine chassis ground.
• Power supply to the unit must be through an IEC-rated isolation transformer.
• The Power supply to the controller must be controlled to ensure that it does not exceed over voltage category II per
EN60204-1 (IEC 240).
• Other requirements of the Machinery Directive involving displays, languages, instructions, Emergency Stop functions,
machine operation, protective guards and interlocks are the responsibility of the machine manufacturer.
• Use a ferrite core on the power wiring to reduce radiated emissions from the DC power lines. It is recommended to
use a 140Ohm@100MHz ferrite core with the DC power lines looped through the core once. Position the ferrite core
less than 1" away from the DC power connection points on the back of the UNIT.
2.3.3 Safety Guide Lines for EU Installations
• Only qualified personnel should be allowed to specify, apply, install, operate, maintain or perform any other function
related to HMI products. Qualified persons are defined as follows:
System application and design engineers who are familiar with the safety concepts of automation equipment.
Installation, start-up, and service personnel who are trained to install and maintain automation equipment.
Operating personnel trained to operate automation equipment and trained on the specific safety issues and
requirements of the particular equipment.
• Make sure that the voltage range for the equipment is correct before switching on the equipment.
• Emergency-tripping devices in accordance with EN60204/IEC204 must be effective in all operating modes of the
automation equipment. Resetting the emergency off device must not result in any uncontrolled or undefined restart of
the equipment.
• Automation equipment and its operating elements must be installed so that unintentional operation is prevented.
• Make sure that operating sequences, interrupted by a voltage dip or power supply failure, resume proper operation
when the power supply is restored. If necessary, the equipment must be forced into the "emergency off" state.
• Install the power supply and signal cables so that inductive and capacitive interference voltages do not affect
automation functions.
