2.4 CE Requirements
2.4.1 EU directives that apply to the MMI-1XX Series:
•
EMC Directive (89/336/EEC, 92/31/EEC, 93/68/EEC) electromagnetic emissions and immunity
•
Low Voltage Directive (73/23/EEC, 93/68/EEC) electrical safety
•
Machinery Directive (89/392/EEC, 91/368/EEC, 93/44/EEC, 93/ 68/EEC) machine safety
MMI products will be CE-marked to indicate compliance with the EMC Directive. Declarations of
Conformity that specify the directive(s) and the catalog numbers of the products covered are available
from Kessler Ellis Products.
The MMI has been designed to operate satisfactorily in electromagnetic noise (immunity) and without
emitting high levels of electrical noise into the environment (emission). The MMI was 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.
•
CISPR (EN 55011) Group 1, Class A Radiated Emissions levels
•
EN50081-2 Generic emission standard, industrial environment
(Also US FCC Class A)
•
EN50082-2 Generic immunity standard, industrial environment
2.4.2 General Installation Guide Lines for EU Installations.
•
Be aware that wiring leaving the cabinet where the MMI 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.
•
The MMI power supply must be through an IEC-rated isolation transformer.
•
The Power supply to the PLC must be controlled to ensure that it does not exceed overvoltage
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.
