4-4 1. Installation Procedure
Mounting Spatial Restrictions
Mount the V9 series unit with approximately 100 mm of space around the periphery of the unit.
Mounting Angle
The mounting angle differs depending on the mounting orientation. Mount the unit within the angle
ranges shown in the table below.
* When supplying power externally from a modular jack (MJ1/MJ2) or USB-A, mount the V9 series
unit at an angle between 60 and 120.
Ambient Temperature
Use the V9150 series in an ambient temperature range of 0 °C to +40 °C (wet-bulb temperature of
39 °C or less).
Regarding other models, use in a range of 0 °C to +50 °C (wet-bulb temperature of 39 °C or less).

Connections
Power Supply Cable Connection
Connect the power supply cable to the terminal on the backside of the unit.
For information on the specifications of the power supply cable and the tightening torque of the
screws on the power supply terminal block, refer to the following table.
DANGER
There is a risk of electrical shock.
Shut the power off before connecting the power supply cable.

Notes on the Power Supply
The power supply must be used within allowable range of voltage fluctuation.
Use a power supply with low noise between cables and between the ground and cables.
Use the thickest power supply cable possible that is twisted to minimize drops in voltage.
Keep power supply cables away from high-voltage, large-current carrying cables.
When using models V9101iW or V9071iW (capacitive type touch panel), use a Class 2 power
supply for a 24-VDC input.
Notes on Usage of the 100 to 240 VAC Specification
The V9 series is an overvoltage category II product.
While the use of an isolating transformer generally improves noise resistance, if the V9 series unit
is a significant distance from the secondary port of the transformer or noise interference occurs
easily, an isolating transformer is ineffective.
If any power voltage fluctuation caused by noise is expected, the use of a voltage stabilizer
(effective for noise resistance) is recommended.
Grounding
An independent grounding must be used for the unit.
Use a grounding cable with a nominal cross section of more than 2 mm
2
.
Set the grounding point near the unit to shorten the distance of grounding cables.
The signal ground (SG) and frame ground (FG) are connected inside the V9150 series unit.
* For models V9101iW and V9071iW (capacitive type touch panel), use independent grounding.
