ESD
This equipment contains components which are sensitive to "ESD" (Electro Static
Discharge). Therefore, ESD protection measures must be observed when touching the IDU.
Anyone responsible for the installation or maintenance of the IDU must use an ESD Wrist
Strap.
Additional precautions include personnel grounding, grounding of work bench, grounding of
tools and instruments as well as transport and storage in special antistatic bags and boxes.
Laser
Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.
The optical interface must only be serviced by qualified personnel, who are aware of
the hazards involved to repair laser products.
When handling laser products the following precautions must be taken:
•
Never look directly into an open connector or optical cable.
•
Before disconnecting an optical cable from the optical transmitter, the power should be
switched off. If this is not possible, the cable must be disconnected from the transmitter before
it is disconnected from the receiver.
•
When the cable is reconnected, it must be connected to the receiver before it is connected to
the transmitter.
Grounding: This equipment is designed to permit connection between the earthed conductor of the
DC supply circuit and the earthing conductor at the equipment.
Restricted Access Area: DC powered equipment should only be installed in a Restricted Access
Area.
Installation Codes: The equipment must be installed according to country national electrical codes.
For North America, equipment must be installed in accordance to the US National Electrical Code,
Articles 110-16, 110-17 and 110-18, and the Canadian Electrical Code, Section 12.
Overcurrent Protection: A readily accessible listed branch circuit overcurrent protective device,
rated 15 A, must be incorporated in the building wiring.
Grounded Supply System: The equipment shall be connected to a properly grounded supply
system. All equipment in the immediate vicinity shall be grounded the same way, and shall not be
grounded elsewhere.
Local Supply System: The DC supply system is to be local, i.e. within the same premises as the
equipment.
Note
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
