Instrument Care and Safety Information
Please read the whole of this section before using your ViaLiteHD product. It contains important
safety information and will enable you to get the most out of your Fibre Optic Link.
Electrical Safety
The
ViaLiteHD
chassis is a Safety Class 1 product (having metal case directly
connected to earth via the power supply cable).
When operating the equipment note the following precautions:
Hazardous voltages exist within the equipment. There are no user serviceable
parts inside; the covers should only be removed by a qualified technician.
There are no user replaceable fuses in the chassis mounted equipment.
Replacement should only be carried out by a
ViaLite Communications
technician.
The chassis earth stud SHOULD be connected to the safety earth.
When using a 2 pin power supply cable the chassis earth stud MUST be
connected to the safety earth.
The
ViaLiteHD
Power Supply Modules do not have an isolating switch on the
mains voltage inlet. For this reason, the
ViaLiteHD
Chassis must be installed
within easy reach of a clearly labelled dual pole mains isolation switch, which
supplies the equipment.
ESD Precautions
The
ViaLiteHD
RF Fibre Optic Link is equipped with high frequency active
electronics, without the correct handing they will be susceptible to damage.
Precautions for handling electro-static sensitive devices should be observed
when handling all
ViaLiteHD
modules.
Technicians should ensure that they use effective personal grounding (i.e.
ESD wrist strap etc.) when servicing the equipment.
Any equipment or tools used should be grounded to prevent static charge
build-up.
Good practice should be observed at all times for reference see relevant
standards. EN 61340-5-
1, “Protection of Electronic Devices from Electrostatic
Phenomena
– General Requirements”
Optical Safety
The
ViaLiteHD
RF Fibre Optic Transmitters contain optical sources (usually laser
diodes) operating at nominal wavelengths of 1270nm to 1610nm.
These devices are rated as EN60825-1:2007 as CLASS 1 radiation emitting
devices. A class 1 laser is safe under all conditions of normal use.
When operating the equipment note the following precautions:
Never look into the end of an optical fibre directly or by reflection either with
the naked eye or through an optical instrument.
Never leave equipment with radiating bare fibres
– always cap the connectors.
Do not remove equipment external covers when operating.
