point earth bonding. Use a cable meeting local wiring requirements and attach it to the two earth
bonding lugs located on the motor housing and grinder top cover.
Typical earth bonding points for grinder and drive. To be connected to local
earthing points on installation. To be carried out by suitably qualified installation
contractor and following local country requirements and legislation. Earth
bonding cables not supplied.
Electrical installation
The grinder is protected by a PLC control unit set to the correct operating philosophy.
Only PLCs supplied or approved by Sulzer should be used. Failure to observe this
requirement may cause premature machine failure and could invalidate the warranty of
the machine. It is also important that the PLC be correctly wired into the panel (refer to
the Controller Manual if controller is supplied).
Before installing the grinder please ensure that all plugs and inspection plates are
replaced.
Electrical connection should only be made using equipment suitable for both rating and
environment. Where any doubts exist regarding the suitability of equipment, Sulzer
should be consulted before proceeding. Earthing points will be provided on ATEX rated
electric drives (if supplied) and it is essential that these are correctly connected. The
electrical installation should include appropriate isolating equipment to ensure that the
grinder and drive assembly is safe to work on.
