Determining GPON 452/454 Enclosure Location
General mounting requirements for the outdoor GPON 452/454 are as follows:
■ Maintain proper airflow in and around the unit at its final mounted location. Do not install
siding and other building material around the outside of the enclosure to prevent excessive
heat buildup and ultimate product failure.
■ Mount the unit within proximity of the AC electrical power meter where the Multi-Ground
Neutral (MGN) is easily accessible.
■ Mount the unit away from down spouts, permanent water sprinklers, or other water
sources.
■ Consider proper clearances for opening of the swinging GPON 452/454 covers.
The height of the mounting can vary, however, it is recommended that the enclosure be
installed at a vertical distance of approximately 4 feet (1.2 meters) from grade. This height
lends to ease of installation/repair. Naturally, this mounting is dependent on the height of the
customer provided inside wire and/or length or location of the buried fiber drop, which is
assumed to enter the GPON 452/454 from the ground upwards.
The enclosure is mounted vertically. If at all possible, the enclosure should be surface
mounted on a flat surface.
WARNING!
f
■ Ensure the GPON 452/454 is grounded before making any other connections.
■ Before making any power connections to this equipment, verify the power is off (fuse
removed/breaker tripped).
CAUTION!
f
To reduce the risk of fire, use minimum no. 26 AWG telecommunications line cord.

necessary.
1. Place the GPON 452/454 horizontally on a flat surface.
2. Open the Outer Enclosure by loosening the security screw.
3. Loosen the Electronics Module security screw.
4. Swing GPON 452/454 Electronics Module out.
5. The Electronics Module can be removed from the housing by gently pulling it from the
hinge points on the GPON 452/454.
