The above named ports are classified as SELV (Safety Extra Low Voltage) in accordance with in Clause 2.3
of EN60950 (BS7002, IEC950 as applicable), and must only be connected to equipment which similarly
complies with the SELV safety classification.
TNV Ports:
i)
ISDN port (when fitted)
ii)
Voice ports (PBX extension, trunk ports, telephones or Tie-line
connections) (when fitted)
The above named ports classified as TNV (Telecom Network Voltage) in accordance with clause 6.2 of
EN60950 (BS7002, IEC950 as applicable) must only be connected to circuits complying with the
requirements therein.
The unit complies with EMC emissions standards EN55022 and immunity standards EN50082-1 and
50082-2. In order to meet the requirements of these standards it must be operated with screened link,
channel and supervisor cables. Failure to do so may result in non-compliance.
ESD PRECAUTIONS AND STATIC SENSITIVE CARD HANDLING
Vocality International Ltd. observe the general requirements of BS EN 100015-1 (1992) 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 Option Cards.
All cards are assumed to contain at least one ESD and therefore 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 an ESDs may become exposed to ESD. The packaging of Vocality International Ltd.
products is classified as secondary, for physical protection only.
Cards should be handled in an ESD Protected Area (EPA) using approved materials (wrist straps, bonding
cords etc) from recognized suppliers.
ESDs should always be protected by primary packaging when moving between EPAs or EPA and field
sites. Equipment containing ESDs devices in primary packaging (e.g. the metal enclosure) are moved off-
site using additional secondary packaging for mechanical protection. Within the EPA, cards should be
stored in their primary packaging in electrostatic dissipative bags.
