ULTRAFLOW® 54 · DN150-300
24 VAC
This PCB module is glvniclly seprted
from the 24 VAC mins supply nd is both
suitble for industril instlltions with joint 24
VAC supply nd individul instlltions, which
re supplied by  seprte 230/24 V sfety
trnsformer in the min electricl pnel. The
module includes  double-chmber sfety
trnsformer, which fulfils double-isoltion
requirements when the cover is mounted on
the electronics box. Power consumption is less
thn 1 VA or 1 W.

Ntionl regultions for electric instlltions must be observed. The 24 VAC module cn be
connected/disconnected by the district heting sttion’s personnel, where-s the fixed 230/24 V
instlltion in the min electricl pnel must only be crried out by n uthorized electricin.
Note: This module cnnot be supplied by 24 VDC (direct current).
230/24 V, sfety trnsformer
The 24 VAC module is specilly suited for instlltion together
with  230/24 V sfety trnsformer, e.g. type 66-99-403, which
cn be instlled in the min electricl pnel before the sfety
rely. When the trnsformer is used the totl power consumption
of the meter incl. the 230/24 V trnsformer will not exceed 1.7 W.

2.2.3 Mins supply cble
ULTRAFLOW® 54 is vilble with mins cble
H05 VV-F for either 24 V or 230 V (l=1.5 m):
Figure 11. Mins cble (2 x 0.75 mm²), mx. 6 A fuse.
”H05 VV-F” is the designtion of  strong PVC mntle, which withstnds mx. 70 °C. Therefore, the
mins cble must be instlled with sufficient distnce to hot pipes etc.
2.2.4 Cble connections
Cble dimension of connections: 4.5…10 mm.
Tightening torque: 4 Nm.
Note: If ULTRAFLOW® 54 is mounted with  glvniclly coupled output module, or if  glvniclly
seprted output module is used in combintion with bttery supply the unused cble
connection must be seled off s shown in Figure 12.
