Terminal Adapter Kit; Tightening-Up Torques; Installation Of 24 Volt External Dcsupply; Installation Of Brake Resistor Temperature Switch - Danfoss VLT 5000 Series Manual

I Terminal adapter kit
The terminal adapter kit is an optional kit for VLT
5300-5500, VLT 6350-6650 and VLT 8350-8550.
The terminal adapter kit makes it possible to connect
the power wires with the power terminals i.e. the
mains-, motor-, load sharing and brake terminals.
The ordering numbers of the terminal adapter kit are:
VLT 5300-5500/6350-6550 EX, DX
VLT 5300-5500 EB, DE
VLT 8350-8550 EX, DX
I Tightening-up torques
The table shows the torque required when fitting
terminals to the VLT frequency converter.
For VLT 5300-5500, VLT 6350-6550 and VLT
8350-8550 the cables must be fastened with
bolts or the terminal adapter kit. These figures
apply to the following terminals:
Mains terminals
Motor terminals
Earth terminal
Brake resistor

For the brake terminals, the tightening-up torque
is 11.3 (8.33 lb-ft) Nm and the bolt size M8.
I Installation of 24 Volt external DCsupply
Torque: 0.5 - 0.6 Nm
Screw size: M3
No. Function
35, 36 24 V external DC supply
24 V external DC supply can be used as low-voltage
supply to the control card and any option cards
installed. This enables full operation of the LCP
(incl. parameter setting) without connection to mains.
Please note that a warning of low voltage will be
given when 24 V DC has been connected; however,
there will be no tripping. If 24 V external DC supply
is connected or switched on at the same time as
the mains supply, a time of min. 200 msec. must
be set in parameter 120 Start delay.
A pre-fuse of min. 6 Amp, slow-blow, can be
fitted to protect the external 24 V DC supply.
The power consumption is 15-50 W, depending
on the load on the control card.
NB!:
Use 24 V DC supply of type PELV to ensure
correct galvanic isolation (type PELV) on the
control terminals of the VLT frequency converter.
