This document provides detailed installation instructions for the CSNV1500 current sensor to ensure optimal sensor performance.
It includes recommendations for the shape of the primary conductor and the clear distance required to avoid disturbances caused by external magnetic fields and ferromagnetic materials.
For accurate installation, it is highly recommended to follow the guidelines provided in this guide or consult a Honeywell engineer.

Busbar Specifications:

Width: 18 mm
Thickness: 3 mm

Installation Guide

The CSNV1500 current sensor detects the magnetic field generated by the primary current flowing through the conductor and converts it into current readings. The primary conductor can be either a cable or a busbar, with the long straight copper bar positioned across the center of the circular hole of the sensor. Proper installation of the primary conductor is crucial for accurate sensor readings. Figure 2 shows some recommended installation configurations.

Figure 2: Recommended Installation Configurations

For a Z-shape primary conductor installation, the distance between the Z-shape and the sensor should be maintained at a minimum of 20 mm, regardless of the angle between the current sensor and the conductor.
Figure 7 shows the current error at different angles and distances for a Z-shape busbar installation.

Figure 7: Z-shape Busbar – Current Error at Different Angle and Distance

Based on test results, it has been determined that the distance and angle of the busbar have minimal influence on the sensor output.
To eliminate the thermal effect of the busbar, a fixed distance of 10 mm between the sensor and the busbar is recommended, regardless of the angle, as shown in Figure 8.

FAQ

Q: Can the CSNV1500 current sensor be used as a safety or emergency stop device?

A: No, the CSNV1500 current sensor should not be used as a safety or emergency stop device. It is not designed for such applications and failure to comply with this instruction could result in personal injury.

Q: What is the recommended installation position for the busbar?

A: The busbar should be placed in the center area of the sensor aperture to ensure accurate readings. Please refer to Figure 5 for the suggested installation position.

Q: What is the recommended distance between the Z-shape busbar and the sensor?

A: For a Z-shape busbar, a minimum distance of 20 mm between the busbar and the sensor is recommended to avoid any disturbances.
Please refer to Figure 7 for more information.

Q: How thick should the primary conductor be?

A: The primary conductor should have a thickness of 3 mm to ensure accurate measurements with the CSNV1500 current sensor.

WARNING PERSONAL INJURY WARNING

DO NOT USE these products as safety or emergency stop devices or in any other application where product failure could result in personal injury.
Failure to comply with these instructions could result in death or serious injury.

PRODUCT DESCRIPTION

CSNV1500 current sensor is based on Hall technology, with closed-loop and CANBUS output. It can measure 1500 A-rated current using a proprietary digital compensation technology.

SCOPE

This document provides installation instructions for CSNV1500 for optimal the best sensor performance.
It makes recommendations for the primary conductor shapes and clear distance to avoid any disturbances due to the external magnetic fields and ferromagnetic material.
To ensure the accuracy of CSNV1500, Honeywell strongly suggests the customer install a sensor, relay, and copper bar as described in this guide, or check the installation with a Honeywell engineer.
The busbar used in the document is made of copper, 18 mm width, and 3 mm thickness.

INSTALLATION GUIDE

Primary conductor shapes
When the primary current flows through the conductor, a magnetic field will be generated. The CSNV1500 can sense the magnetic field and convert it to current readings.
The primary conductor can be a cable or busbar, and the long straight copper bar across the center of the circular hole of the sensor.
If the primary conductor is not properly installed, the sensor accuracy may be affected as shown in Figure 1. Some recommended installation is shown in Figure 2.
Figure 2a. Recommended Installation: CSNV1500 with Z-Shaped Busbar at 180° and 15 mm Distance Position
Figure 2b. Recommended Installation : CSNV1500 with L-Shaped Busbar Top Side at 0° and 20 mm Distance Position
Figure 2c. Recommended Installation: CSNV1500 with L-Shaped Busbar Top Side at 90° and 20 mm Distance Position
Figure 2d. Recommended Installation: CSNV1500 with U-Shaped Busbar at 90° and 20 mm Distance Position
The shape of the primary conductor and the clear distance to avoid any disturbances will be discussed on the following page.
The angle in test items are defined in Figure 3, and the top and bottom side of the current sensor are defined in Figure 4.

Figure 4. Current Sensor Side Definition

Based on test results, Honeywell strongly recommends the customer put the conductor in the center area of the sensor aperture as shown in Figure 5.

Figure 5. Busbar Suggested Installation Position

Z-Shape Conductor

The Z-shape primary conductor and the current sensor are installed in Figure 6. The distance of the Z-shape to the sensor is recommended to be above 20 mm, regardless of the angle between the current sensor and the conductor.
According to the definition of angle in Figure 3, some angles and distances have been tested as shown in Figure 7.
Figure 6. CSNV1500 with Z-shaped Busbar Installation at an Angle of 180° at 20 mm

Figure 7. Z-shape Busbar – Current Error at Different Angle and Distance

Based on the test results of the Z-shape installation, the distance and the angle of the busbar can hardly influence the sensor output.
To eliminate the thermal effect of the busbar, a 10 mm distance, regardless of the angle between the sensor and the busbar is recommended, as shown in Figure 8.

Figure 8. Z-shape Installation – Not Recommended Area

L-shape conductor

For the L-shape primary conductor, the distance of the L-shape to the sensor and the angle related to the current sensor are the two most important parameters, installed in Figure 9.
According to the definition of angle in Figure 3, some angles and distances have been tested as shown in Figures 10 & 11.

Figure 9. L-shape Busbar Installation at an Angle of 0° at 20 mm

Figure 10. L-shape Busbar – Current Error at 20 mm

Figure 11. L-shape Busbar – Current Error at Different Angle and Distance

Based on the test results of the L-shape busbar, Honeywell recommends the primary conductor should not be between the angle 180° and 270°, others are shown in Figure 12.
Figure 12. L-shape Installation – Not Recommended Area

U-shape conductor

For the U-shape primary conductor, the distance of the U-shape to a sensor and the angle related to the current sensor are the two most important parameters, so only installation from 0° to 90° is recommended, and the distance between the current sensor and copper bar should be above 20 mm, as shown in Figure 13. Several angles and distances have been tested as Figure 14.

Nearby Ferromagnetic Material

Metal Bracket Installation

The nearby ferromagnetic material can change the magnetic field distribution, which may have an impact on accuracy. Ferromagnetic material includes iron mounting brackets, iron screws, etc., as shown in Figure 15.
All types of iron brackets and iron bolt nuts have been tested and installed on the side of the sensor QR code, which will not affect the accuracy.

Figure 15. Installation with Bracket

Relative Position of High Voltage Relay and Sensor

The nearby ferromagnetic material can change the magnetic field distribution, which may have an impact on accuracy. Ferromagnetic material includes high voltage relays with built-in permanent magnets, etc.
To ensure that the accuracy is not affected, make sure that the bottom surface of the sensor (with connect surface) deviates from the relay, and the top surface of the sensor (with QR code surface) faces the relay, and the distance is more than 10 mm, otherwise, the accuracy may be affected.
To ensure the accuracy of CSNV1500, Honeywell strongly suggests that the customer install the sensor, relay, and copper bar as described in this guide, or check the installation parameters with a Honeywell engineer.
