(2) EU compliance
The EC directives were issued to standardize the regulations of the EU countries and ensure
smooth distribution of safety-guaranteed products. The CE marking proves the compliance of the
manufacturer with the EC directives, and this marking also applies to machines and equipment
incorporating servos.
(a) EMC requirement
LECSN2-T□ drivers comply with category C3 in accordance with EN 61800-3. As for I/O wires
(max. length 10 m. However, 3 m for STO cable for CN8.) and encoder cables (max. length 10
m), use shielded wires and ground the shields. Install an EMC filter and surge protector on the
primary side for input and output of LECSN
□
-T□ drivers. The following shows recommended
products.
EMC filter: Soshin Electric HF3000A-UN series, TF3000C-TX series, COSEL FTB series
Surge protector: Okaya Electric Industries RSPD series
Line noise filter: Mitsubishi Electric FR-BLF
LECSN2-T□ drivers are not intended to be used on a low-voltage public network which supplies
domestic premises; radio frequency interference is expected if used on such a network. The
installer shall provide a guide for Installation and use, including recommended mitigation devices.
To avoid the risk of crosstalk to signal cables, the installation instructions shall either recommend
that the power interface cable be segregated from signal cables.
Use the DC power supply installed with the drivers in the same cabinet. Do not connect the
other electric devices to the DC power supply.
(3) USA/Canada compliance
This driver is designed in compliance with UL 508C and CSA C22.2 No. 14.
(a) Installation
The minimum cabinet size is 150% of each LECSN2-T□ driver's volume. Also, design the
cabinet so that the ambient temperature in the cabinet is 55 °C or less. The driver must be
installed in the metal cabinet. Additionally, mount the driver on a cabinet that the protective
earth based on the standard of IEC/EN 60204-1 is correctly connected. For environment, the
units should be used in open type (UL 50) and overvoltage category shown in table in app.
4.8.1. The driver needs to be installed at or below pollution degree 2. For connection, use
copper wires.
(b) Short-circuit current rating (SCCR)
Suitable For Use On A Circuit Capable Of Delivering Not More Than 100 kA rms Symmetrical
Amperes, 500 Volts Maximum.
