Requirement To Conform To The Low-Voltage Directive - LS ELECTRIC XGT Series User Manual

10.2 Requirement to conform to the Low-voltage Directive

The low-voltage directive requires each device that operates with the power supply ranging from 50V to 1000VAC and 75V
to 1500VDC to satisfy the safety requirements. Cautions and installation and wiring of the series PLC XGT series to conform
to the low-voltage directive are described in this section. However, LSIS will not guarantee that the overall machinery
manufactured according to the details conforms to the below-described directives. The method of conformance to the EMC
directive and compliance to the EMC Directive must be determined by the manufacturer of the machinery.
10.2.1 Standards applicable to XGT series
The XGT PLC complies with EN6100-1 (safety of equipment used in measurement and control laboratories. XGT series
PLCs have been developed in accordance with the above standards for modules operating at rated voltage of AC50V /
DC75V or higher.
10.2.2 Selection of XGT Series PLC
(1) Power supply module
There are dangerous voltages (higher than 42.4V peak) inside the power supply modules of the Rated input voltage
AC110/ 220Vtes. Therefore, the CE mark-compliant models feature enhanced insulation strong primary and secondary
windings.
(2) I/O Module
There are dangerous voltages (voltages higher than 42.4V peak) inside the I/O modules of the AC110/220V rated I/O
voltages. Therefore, the CE mark-compliant models are enhanced in insulation internally between the primary and
secondary.
The I/O modules of DC24V Rated input are out of the low-voltage directive application range.
(3) CPU module ,base
Since the above modules use DC5V and 3.3V circuits internally, they are not subject to the low voltage command.
(4) Special, Communication module
Special and communication modules are DC24V or less in rated voltage, therefore they are out of the low-voltage
directive application range.
