Connection examples, VLT 6000 HVAC

The diagram below gives an example of a typical
VLT 6000 HVAC installation.
The mains 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 frequency converter.
An external DC supply or a 12-pulse option can
be connected to terminals 88 and 89. Please ask
Danfoss for a Design Guide to learn more.
Analogue 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
Analogue inputs in parameter group 300.

VLT 6000 HVAC Series
There are 8 digital inputs, which can be connected
to 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 analogue/digital outputs (terminals
42 and 45), which can be programmed to show
the present status or a process value, such as
0-f . Relay outputs 1 and 2 can be used for
MAX
giving the present status or a warning.
On terminals 68 (P+) and 69 (N-) RS 485 interface,
the frequency converter can be controlled and
monitored via serial communication.
