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 from your Fibre Optic link.
Electrical Safety
The
ViaLiteHD
chassis provides the termination for power inputs and can be fitted with power supplies.
The
ViaLiteHD
chassis is a Safety Class 1 product (having metal chassis 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 MUST NOT be removed.
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.
PSU modules are fused on the mains live feed only. A second fuse should be used for the neutral connection
where the polarity of the connectors can be reversed; rating should match those given in section 5.1.1.
ESD Precautions
The
ViaLiteHD
chassis is not equipped with any active electronics but it may be fitted with them.
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
chassis is not equipped with optical units but it may be fitted with them
The
ViaLiteHD
RF Transmitter and Transceiver modules contain laser diode sources operating at nominal
wavelengths of 1270nm to 1610nm.
These devices are rated as EN60825-1:2007 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.
Hot surface
The
ViaLiteHD
Redundancy load module may have hot surfaces when operating under fulll load. The hot surfaces are
not accessible when fitted in an approved chassis installation.
Suitable precaution should be taken when handling this device.
Allow to cool for 10 minutes
Do not touch metallic surfaces or printed circuit board when hot.
When handling, hold front panel and handle only.
