WARNING! The AQUAVAR CPC adjustable speed AC drive with Input Disconnect should ONLY be
installed by a qualified electrician.
WARNING! Even when the motor is stopped, dangerous voltage is present at the Power Circuit terminals
U1, V1, W1 and U2, V2, W2 and, depending on the frame size, UDC+ and UDC-, or BRK+ and BRK-.
WARNING! Dangerous voltage is present when input power is connected. After disconnecting the
supply, wait at least 5 minutes (to let the intermediate circuit capacitors discharge) before removing the
cover.
WARNING! Even when power is removed from the input terminals of the AQUAVAR CPC, there may be
dangerous voltage (from external sources) on the terminals of the relay outputs.
WARNING! When the control terminals of two or more drive units are connected in parallel, the auxiliary
voltage for these control connections must be taken from a single source which can either be one of the
units or an external supply.
WARNING! The AQUAVAR CPC will start up automatically after an input voltage interruption if the
external run command is on.
WARNING! When the AQUAVAR CPC with Input Disconnect is connected to the line power, the Motor
Terminals T1, T2 and T3 are live even if the motor is not running. Do not make any connections when the
AQUAVAR CPC with Input Disconnect is connected to the line. Disconnect and lock out power to the
drive before servicing the drive. Failure to disconnect power may cause serious injury or death.
NOTE! For more technical information, contact the factory or your local AQUAVAR representative.
