Magtrol Load Monitoring Units LMU 212 & 217 Chapter 2 – Installation / Configuration
1. Place the jumper according to the selected supply mode (see
figure 2–5
) :
- 'DC' for a DC type supply with a voltage between 20 and 32 VDC
- 'AC' for an AC type supply (230 VAC, 115 VAC or 48 VAC)
2. In case of an AC supply position the switch on (see
figure 2–5
) :
- '230 V' for an AC voltage of 230 VAC
- '115 V' for an AC voltage of 115 VAC
- for operating voltages of 48 VAC or 20 to 32 VDC the position of the switch is irrelevant.

3. Check the rating of the fuse inserted in its support according to the following table:
operating
voltage
supply terminals
fuse switch
0 v (18) n (19) p (20)
¶ 230 VAC earth neutral phase 80 mAT 230 V
115 VAC earth neutral phase 160 mAT 115 V
48 VAC earth neutral phase 400 mAT irrelevant
20 - 32 VDC 0 V — 20 - 32 V 400 mAT irrelevant
A fuse of each rating is supplied with each load monitoring unit.
