■ Connection example VLT 8000 AQUA

The diagram below gives an example of a typical

VLT 8000 AQUA installation.

The line supply is connected to terminals 91 (L1),

92 (L2) and 93 (L3), while the motor is connected to

96 (U), 97 (V) and 98 (W). These numbers can also

be seen from the terminals of the AFD.

An external DC supply can be connected to

terminals 88 and 89.

Analog inputs can be connected to terminals 53 [V],

54 [V] and 60 [mA]. These inputs can be programmed

for either reference, feedback or thermistor. See

Analog inputs in parameter group 300.

There are 8 digital inputs, which are controlled with

24 V DC. Terminals 16-19, 27, 29, 32, 33. These

inputs can be programmed in accordance with the

table in Inputs and outputs 300- 328.

There are two analog/digital outputs (terminals

42 and 45), which can be programmed to show

the present status or a process value, such as

0-f

MAX

. Relay outputs 1 and 2 can be used for

giving the present status or a warning.

On terminals 68 (P+) and 69 (N-) RS 485 interface,

the AFD can be controlled and monitored via

serial communication.

* These terminals can be programmed for

other functions.
