Visit our homepage for this: www.becker-international.com IMPORTANT INFORMATION This quick start guide represents only an excerpt of the VAU 1.1/1-AC operating instructions. The latter should be read thoroughly before initial start-up. The quick start guide contains safety instructions and helps the user to put the basic model of the frequency converter (FC) into operation and to operate it with the default settings.
BECKER VAU 1.1/1-AC DANGER Mortal danger from electric shock! Death or serious injury! Switch the frequency converter to zero potential and protect it against reactivation. The following terminals may still carry dangerous voltages even with the motor at rest: • mains connection terminals 1X1: PE, N, L •...
• Repairs may only be carried out by authorised repair centres. Independent unauthorised interventions may lead to death, personal injury and property damage. Such cases invalidate the warranty by Gebr. Becker GmbH. • No external mechanical loads, e.g. stepping onto the housing, are permitted!
