WARNING! The AQUAVAR adjustable speed AC drive should ONLY be installed by a qualified electri-
cian.
WARNING! Even when the motor is stopped, dangerous voltage is present at the Power Circuit termi-
nals 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, there may be dan-
gerous voltage (from external sources) on the terminals of the relay outputs R01…R03.
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 wall mount version is not a field repairable unit. Never attempt to repair
a malfunctioning unit; contact the factory or your local Authorized Service Center for replacement.
WARNING! The AQUAVAR will start up automatically after an input voltage interruption if the external
run command is on.
WARNING! The heat sink may reach a high temperature, in excess of 200º F. Severe burns are possible.
WARNING! If the drive will be used in a floating network, remove screws at EM1 and EM3 (Frame size
R1…R4), or F1 and F2 (Frame size R5 or R6). See diagrams on pages 24 and 25 respectively.
NOTE! For more technical information, contact the factory or your local AQUAVAR representative.
WARNING! Always consult your local, state, municipal or NEC codes for proper wiring, electrical installa-
tion of inverter drives and AC motors.
