All connection work must be carried out by qualified electricians according to the laws in use in the country
where the variable speed drive is installed. This includes earthing or bonding to ensure that no part of the
equipment directly accessible to the user can be at mains potential or at any other voltage which may be
dangerous.
• The variable speed drive must be powered through an approved breaking device in order to be able to safely turn it off.
• The power supply of the equipment shall be protected against overloads and short circuits.
• Voltages on the network, motor, braking resistance or filter connections can cause fatal electrical shocks. In all cases
the protective plates supplied with the variable speed drive must be correctly installed to protect the user from direct
electrical contact.
