• Precautions for Compliance with Shipping Standards
1. Always install the NS-series PT in a control panel.
2. Install the NS-series PT in a control panel that has air conditioning.
3. Cover the entire surface of the NS-series PT with electromagnetic shielding material and
ground the control panel or operation panel with copper tape or other conductive tape.
4. Completely shield the gap at openings in the control panel or operation panel with a
gasket.
5. Completely shield the gap between the NS-series PT and the panel cutout with copper
tape or other conductive tape before securing the NS-series PT with the mounting
bracket.
6. Connect a noise filter to the power supply line connected between the 24-VDC and
0-VDC terminals.
