   FITTING INSTRUCTIONS

   APPLICATION
   Single wire armoured cables (extruded
      or tape bedded).
   Wherever circumstances dictate a       "barrier gland" type is required.
   IP RATINGS
   The flanged gland compiles with IP66.
   The screwed entry gland is normally       rated at IP54 but can be enhanced to       IP66 by the inclusion of an "O" ring as       an optional, factory - fitted, extra.
      (prices and delivery details available on       request)
   Adequate sealing arrangements must
      be made between the gland and the      enclosure.
   Refer to general information sheet for      comments on IP ratings.

   SIZING PROCEDURE
   Refer to CMP sizing charts for cables to       British Coal Spec. Nos 295 and 504.
      For other cable types the table below       will assist in selecting the correct size.
   The choice of screwed or spigot entry       and metric or imperial diametres will       depend upon the host enclosure. In the       event of any difficulty with sizing, Victor       would be pleased to assist.
