INSTALLATION

Electronic modules can be damaged by ESD. When handling
modules, wear an antistatic discharge wrist strap to prevent
damage to electronic components. Place modules in antistatic
packing material when transporting or storing. When working on
modules, always place them on an approved antistatic mat that is
electrically grounded.
After unpacking the DDM+ HTU-C, inspect it for damage. If damage has occurred, file a claim
with the carrier then contact ADTRAN Customer Service. Refer to
further information. If possible, keep the original shipping container for returning the DDM+
HTU-C for repair or for verification of shipping damage.

Several DDM+ HTU-Cs can be mixed with other DDM+ standard plug-ins, providing that the
total current draw per shelf side is ≤ 5 amps. Refer to the original equipment manufacturer's
specifications for more detail on specific power requirements of these units.
