WARNING!
The ONT must be powered by a UL Listed Power Supply suitable for
the application (rated 12 VDC, 1.25 A minimum) with an LPS output.
Installation of the Local Power Source will be dictated by on-site
conditions and local telephone company practices.
f
CAUTION!
To reduce the risk of fire, use minimum no. 26 AWG
telecommunications line cord.
Install the UPS
Installation of the Uninterruptible Power Source (UPS) will be dictated by

installation material that is provided with the UPS.
f
CAUTION!
After the ground wire, fiber jumper, and power leads have been
connected, close the ONT and secure it by tightening the inner
security screw.
Ethernet, power and POTS cables, and attached equipment are
intended for use within the same building with equipotential bonding,
and not intended to be placed in separate buildings or structures.
Failure to deploy as described could result in permanent damage
from lightning or other electrical events and voids the warranty.
If it is necessary to connect the Ethernet ports to remote outdoor
equipment or between structures then add an
appropriate protection device per the following:
ADTRAN's Ethernet Port Protection Device (EPPD) (P/N
1700502G1) should be connected between the unit and the outside
plant cable. Use of any Ethernet protector other than ADTRAN's for
this purpose will void the user's warranty.
