Safety Instructions
WARNING: THIS UNIT MUST BE INSTALLED BY TRAINED PERSONNEL ONLY
This unit generates hazardous voltages.
There are no user-serviceable parts.
Do not obstruct the fan or the inlets during operation or the unit may overheat.In the event
of failure, the unit should only be repaired by qualified personnel or returned to the factory.
WARNING: THIS EQUIPMENT MUST BE EARTHED BY THE HOST
This equipment relies on the GROUND connection provided by the M4 stud on the rear
panel. This terminal must be permanently connected to an earth to ensure safe operation, so
that the user and telecom network are adequately protected. Operation without this
connection will nullify its safety approval for connection to a network.
WARNING: ESD PRECAUTIONS AND STATIC SENSITIVE CARD HANDLING
Vocality observe the general requirements of BS EN 61340-5-1 (2001) in all matters relating
to the handling and storage of Electrostatic Sensitive Devices (ESDs) and assemblies. We
recommend strict observance of this standard during the installation of all options cards.
All cards should be handled in an ESD Protected Area (EPA) using approved materials (wrist
straps, bonding cords etc) from recognised suppliers. All cards contain at least one ESD and
all subassemblies containing PCBs should be handled in the same way. Products are designed
with protection components on external and internal connectors where appropriate. User
Manuals, Applications Notes and Modification Instructions contain warnings where ESDs may
become exposed.
The packaging of Vocality products is classified as secondary, for physical protection only.
ESDs should always be protected by primary packaging, when moving from EPA to EPA, or to
field sites. Equipment containing ESDs in primary packaging (for example the metal
enclosure) are moved using secondary packaging for mechanical protection. Within an EPA,
cards should be stored in their primary packaging in electrostatic dissipative bags.
