Tool applications safety When connecting an auxiliary battery (AB) in parallel to the unit battery (CB) with booster cables: Apply the proper tool for each job. With the knowledge connect the + pole of AB to the + pole of CB, then of correct tool use and knowing the limitations of tools, connect the - pole of CB to the mass of the unit.
Leading particulars General description The QAS 30 and QAS 40 are AC generators, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The generator operates at 50/60 Hz, 230/240 V in line-to-neutral mode and 400/480 V in line-to-line mode. The QAS 30 and QAS 40 generators are driven by a fluid-cooled diesel engine, manufactured by KUBOTA.
