Warning
For SFP model AT-SPBD20EPON-13:
Laser Radiation.
Do not view directly with optical instruments.
Class 1M Laser product.
Rayonnement Laser.
Ne pas observer directement à l’aide d’instruments d’optique.
Appareil à Laser de classe 1M.
Warning
To prevent electric shock, do not remove the cover. No user-serviceable parts inside. This unit
contains hazardous voltages and should only be opened by a trained and qualified technician. To avoid
the possibility of electric shock, disconnect electric power to the product before connecting or
disconnecting the LAN cables.
Warning
Do not work on equipment or cables during periods of lightning activity.
Warning
Class I equipment. This equipment must be grounded. The AC power plug must be connected to a
properly wired earth ground socket outlet. An improperly wired socket outlet could place hazardous
voltages on accessible metal parts.
Additional notes and precautions:
Only trained and qualified personnel are allowed to install or to replace this equipment.
The uninterrupted power supply (UPS) unit must be mounted indoors, within 30 cable
feet of the gateway.
The power cord for the UPS is 8 feet long. The UPS must be mounted within 8 feet of a
power outlet.
The iMG can be installed indoors or outdoors.
If using a pluggable external AC power supply (PSU) to provide power, both the iMG
and the AC PSU must be mounted indoors. Refer to “Using an indoor AC Power Supply
Unit (PSU) with the iMG” on page 26.

AT-iMG2400 Series Installation Guide 10
All installation methods shall be in accordance with national and local regulations and
practices. The wiring method should include the use of Listed wire/cable acceptable for
the application per the National Code, and should be one that an Authority Having
Jurisdiction (AHJ) can approve per the Code.
Per NEC section 800.90 all exposed cables, service wires, or drops when entering a
building must have primary over voltage protection if they are classified as exposed
plant.
All iMG products have surge protection built in to meet EN55024.
AT-iMG2400 series products meet NEBS GR1089 Section 4.12, 6KW Lightning
Protection on the AC interface, when used with the AT-iMG008 series UPS.
Allied Telesis does not warrant against lightening and/or power surges causing damage
to the iMG. Such damage will be the responsibility of the equipment owner.
Ground resistance from the building primary bonding point to earth should be less than
25 ohms.
If the distance between the iMG and the AC meter ground connection is greater than
12-16 feet (the length of the #6 solid copper wire, not the point to point distance), a
separate ground stake should be installed for the iMG ground connection. In this case, it
is imperative that the AT-iMG008/AT-iMG008NB UPS be used, as it will prevent any
ground loop currents from flowing between the iMG and the AC ground system.
