Connecting A Power Supply - Sharp IV-S20 User Manual

Installation Conditions and Method

[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.

Note
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
- The power line between the IV-S20 main housing and the constant-voltage power supply
- Use twisted-pair wire for the power supply line.
