INSTALLATION

Electrostatic Discharge (ESD) can damage electronic modules.
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 220 HTU-C, immediately inspect it for possible shipping damage. If
damage is discovered, file a claim immediately with the carrier, then contact ADTRAN
