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.

PACKAGE INCLUDES...
