Safety and Warning Information
Connect the DIN Rail, via the Model 2A09 End
Clamp, to protective earth ground with low
impedance. The modules are grounded to PE
when they are snapped onto the DIN Rail. A
Model 2A09 End Clamp on each side of the
module bundle on the DIN rail prevents
accidental disconnection of the modules’
interconnection bus.
