Primary safety on 730 series pumps is provided by the tool-lockable
pumphead track. Secondary (backup) protection is provided in the form of an
electrical guard switch which stops the pump if the pumphead track is
opened. The electrical guard switch on cased pumps should never be used as
primary protection. Always disconnect the mains power supply to the pump
before opening the pumphead guard.
