Cleaning fiber-optic connectors
Warning
Never clean an optical connector attached to a fiber that is carrying light.
Particles of foreign matter on the tip of a ferrule can have a disabling effect on fiber-
optic transmission. Fiber-optic connectors need to be cleaned every time they are
mated and unmated; it is essential that fiber-optic users develop the necessary
discipline to always clean the connectors before they are mated.
Use a commerially available cleaning kit specifically designed for fiber-optic
connectors and follow the manufacturer's instructions carefully.
• The connector sections to be cleaned include the tips and sides of ferrules, the
interior walls of alignment sleeves, and the interior and exterior of connector
shells.
• For plugs, the interior surfaces of alignment sleeves and the tips of ferrules are
to be cleaned with a cleaning stick treated with the appropriate fluid. (Cleaning
sticks with a slender design are available that allow alignment sleeves to be
cleaned without having to detach them.)
• For jacks, it is important to clean both the tips and sides of the completely
protruding ferrules.
• Both the male and female connector shells tend to attract dust and metal
particles, so it is important to clean both the insides and outsides.
• The fiber end face and ferrule must be absolutely clean before it is inserted
into a transmitter or receiver.
• Mate the connector immediately! Don't let the connector lie around and
collect dust before mating.
• Air can be used to remove lint or loose dust from the port of a transmitter or
receiver to be mated with the connector. Never insert any liquid into the ports.

Earthing
This unit has a protective earth terminal (M5-screw) This terminal is internally
connected to the protective earth conductor of the power cable.
The unit must be connect to earth either by using a earthed mains power cable OR
by connecting a separate earth cable between the protective earth terminal and the
building’s central earth.
Mains lead wiring for UK users
The wires in the mains lead are colored in accordance with the following code:
GREEN and YELLOW - EARTH,
BLUE - NEUTRAL,
BROWN - LIVE
As the colors of the wires in the mains lead of this apparatus may not correspond
with the colored markings identifying the terminals in your plug proceed as follows:
• The wire colored GREEN and YELLOW must be connected to the terminal on
the plug marked with the letter E or by the safety earth symbol or colored
GREEN or GREEN and YELLOW.
• The wire colored BROWN must be connected to the terminal marked with the
letter L or colored RED.
• The wire colored BLUE must be connected to the terminal marked with the
letter N or colored BLACK.
Ensure that your equipment is connected correctly - if you are in any doubt consult a
qualified electrician.
