Connection example, 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 VLT 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.

There are 8 digital inputs, which can be
connected to terminals 16-19, 27, 29, 32, 33.
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 giving
MAX
the present status or a warning.
On terminals 68 (P+) and 69 (N-) RS 485
interface, the VLT frequency converter can be
controlled and monitored via serial
communication.
