Installation Conditions and Method
6
To improve the noise resistance of the constant-voltage power supply connected to the
IV-S20 main housing, 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-S20 main housing and the constant-voltage power supply
must be as short as possible. (Recommended distance: less than 30 cm)
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.
Note
[3] Connecting a power supply
Connect a commercially available constant-voltage power supply to the power terminals (POWER:
+24 V, 0 V) on the IV-S20 main housing.
Use a 24 VDC
±
10%, 350 mA or more constant-voltage power supply.
- Use an individual power supply to supply power to the IV-S20 main housing. 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 IV-S20 main housing may be damaged.
- Only connect or disconnect the camera cable and other equipment while the power is OFF.
