CNS Notes
CE Marking Notes
The GLC150-**41-****-24V units are CE marked products that conform to EMC
directives EN55011 class A and EN61000-6-2.
Conformance Standards to EMC Directives
The EN61000-6-2 standard requires that products connected to an unprotected DC
line have 500V resistance (normal mode/common mode) in accordance with the
61000-4-5 surge test.
However, note that the power supply for the DIO of the LT unit is designed on the
assumption that it is connected to a protected DC power-supply line. Therefore,
the surge test included in this specification is inapplicable.
This LT unit’s 24V Power Input for DIO is not equipped with protection against
lightning surges. Therefore, it is not lightning surge resistant. To make your LT
unit or system compliant with EMC directives, connect the LT unit to surge
protected power, and set up surge resistance for your LT unit or overall system.
For example, when an LT unit mounted to a control panel is supplied DC24V
power in accordance with the EMC directive, this LT unit’s input side is protected
from power surges.
