[4] Wiring of the IV-S30EA1
Connecting a power supply
Connect a commercially available constant-voltage power supply to the power terminals (POWER: +24
V, 0 V) on the IV-S30EA1. Use a 24 VDC ± 10%, 500 mA or more constant-voltage power supply.
- Use an individual and dedicated power supply to supply power to the IV-S30EA1. 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.
Note: To improve the noise resistance of the constant-voltage power supply connected to the
IV-S30EA1, 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 IV-S30EA1 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.
