Wiring
The output voltage of the 24-VDC output will vary with the current consumption
of the load as shown in the following table. Be sure to check the current con-
sumption and allowable voltage ranges of the devices connected before using
these terminals.

Connect a dummy load as shown in the following diagram if the maximum oper-
ating voltage of the connected device is 26.4 V (24 V +10%).

• Resistance of the dummy load:
R=24/(0.3 – I
L
120 Ω when I
240 Ω when I
Not necessary when I

• Capacity of the dummy load resistance:
W=(0.3 – I ) x 26.4 x 5 (Safety factor)
L
30 W (120 Ω) when I
15 W (240 Ω) when I
Note Since the dummy load will generate heat, be careful not to allow any combustible
materials to come in contact with the resistor.
