[3] Connecting a power supply
Connect a commercially available constant-voltage power supply to the power terminals (POWER: +24
V, 0 V) on the controller (IV-S31M/S32M/S33M). Use a 24 VDC ± 10%, 500 mA or more constant-
voltage power supply.
- Use an individual power supply to supply power to the controller. If the power supply is used to power
other equipment, measurement errors may occur.
- Check the polarity of the power supply terminals, +24 V and 0 V. If power is supplied with the polarity
inverted, the controller may be damaged.
- Only connect or disconnect the camera cable and other equipment while the power is OFF.

This distance must be
as short as possible.
(Recommended distance:
less than 1 m)
To improve the noise resistance of the constant-voltage power supply connected to the
controller (IV-S31M/S32M/S33M), observe the following precautions.
- Ground the FG terminal of the constant-voltage power supply according to the class 3
grounding.
- The power line between the controller and the constant-voltage power supply must be
as short as possible. (Recommended distance: less than 1 m)
Do not run the power supply line near any noise generating sources, such as electric
motor lines.
- Use twisted-pair wire for the power supply line.
