CAUTION

• When this unit is earthed via a DIN rail, use a steel or copper rail. Oxide film on the surface of an aluminium rail may lower the electric conductivity between this module and the ground.
• Single mount DIN rail for option code ‘/DR’ is made of aluminum. Connect to ground with ground terminal when this DIN rail is used.
