DRN-PS Ñ DIN Rail Power Supplies

The DRN power supplies are heavy
enough to cause damage and or injury
if dropped during installation. Assure
firm rail mounting before releasing grip
on the unit.

If a rail assembly is to be transported,
then disconnection, dismounting and
separate packing of the power supply is
recommended.

For units that must be shipped installed
on the rail, additional bracing to resist
transportation shocks is recommended.

Do not attempt to install or connect to
the power supply when the mains are
energized.

Warning!
