The VX-820ATEX is approved for use in potentially explosive atmospheres according to the ATEX EC
Directive 94/9/EC.
The Intrinsically safe protection rating for the VX-820ATEX is
Zone 1, Equipment Group II, Gas Group C Temperature Class T4).
The ATEX protection rating for these models is only maintained provided:
The equipment shall not be directly installed or used in any process where its enclosure might be electro-
statically charged by the rapid flow of a non-conductive media.
Use ONLY FNB-V100LIEX Battery Pack. Use of other batteries will invalidate the ATEX Approval.
Battery charging must occur ONLY in non - potentially explosive atmospheres.
Use ONLY ATEX approved accessories in the potentially explosive atmospheres. Connect and disconnect
these accessories only outside the potentially explosive atmospheres.
Ensure that there is no external damage to the radio, antenna or battery before entering the potentially
explosive atmospheres, as it might compromise the safety of the unit. eg an antenna with a damaged end or
insulation must be replaced before use in any potentially explosive atmospheres.
Servicing of ATEX radios can only be carried out Vertex Standard IS authorized personnel, who are aware of
the special parts required and the proceedures necessary to maintain the ATEX protection rating for these
products. Consult your authorized Vertex Standard Dealer for details.
Check the ATEX classification of each accessory listed on page 27 before using. Use of an ATEX accessory
with a lower rating than that of the radio itself will reduce the radio ATEX rating to that of the lower level.
Ambient temp range for the radio is –10 °C to +55 °C.
