Electrical Installation - 24 Volt External Dc Supply; Electrical Installation - Relay Outputs - Danfoss VLT 5000 Series Design Manual

Electrical installation - external fan supply
Torque 0,5-0,6 Nm
Screwsize: M3
Available in 5122-5552, 380-500 V; 5042-5602,
525-690 V, 5032-5052, 200-240 V in all enclosure
types.
Only for IP54 units in the power range VLT 5016-5102,
380-500 V and VLT 5008-5027, 200-240 V AC. If the
drive is supplied by the DC bus (loadsharing), the in-
ternal fans are not supplied with AC power. In this case
they must be supplied with an external AC supply.

Electrical installation - 24 Volt external DC supply

(Only extended versions. Typecode: PS, PB, PD, PF,
DE, DX, EB, EX).
Torque: 0.5 - 0.6 Nm
Screw size: M3
No. Function
35, 36 24 V external DC supply
External 24 V DC supply can be used as low-voltage
supply to the control card and any option cards instal-
led. This enables full operation of the LCP (incl. pa-
rameter 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 con-
sumption is 15-50 W, depending on the load on the
control card.
NB!
Use 24 V DC supply of type PELV to en-
sure correct galvanic isolation (type
PELV) on the control terminals of the fre-
quency converter.
