INSTALLATION GUIDE FOR THE
E-S5VDC
INTRODUCTION
The NTI E-S5VDC Voltage Sensor Adapter monitors DC voltage sources (up to two) when connected to an E-16D/5D/2D Server
Environment Monitoring System(SYSTEM). The voltage sources can be anything with a range between 0 to 5VDC. When
connected to a SYSTEM via 18-24AWG CAT5/5e/6 cable (up to 1,000 feet away), the voltage source(s) can be monitored and the
SYSTEM can be configured to alert users as to variations in the voltage levels.
Features:
Detects and monitors up to two DC voltages, each with a range
of 0 to 5VDC
E-S5VDC provides 12VDC, 25mA for each sensor
8-position screw-terminal connection
Supports 18-24AWG CAT5/5e/6 cable up to 1,000 ft. (not included)
Includes Mounting Ears
CE certified
RoHS compliant
INSTALLATION
Mount the E-S5VDC using the mounting ears provided. To use the ears, remove the screws securing the ears to the rear of the
E-S5VDC, turn the ears around, and reapply the screws. Alternatively, secure one ear to holes on the bottom of the unit so that
it can be hung as shown in the image below.

To mount multiple Sensor Adapters in close proximity to the E-16D, install an extension rail kit (NTI E-RL-16D - sold separately)
and mount Sensor Adapters as seen in the illustration below.
CONNECTION
Note: To prevent damage to the voltage source or the Sensor Adapter proper polarity must be observed when making
connections.
1. Connect a 0-5VDC voltage source to be monitored to the “+“ and “ “ (earth ground) connections of either input 1 or input 2
on the removable terminal block.
2. If the 0-5VDC voltage source is also a sensor (such as the E-AV) requiring external 12VDC power, then connect its power
terminals to the “12V” and “ “ (earth ground) on the removable terminal block.
Note: The wire connection terminal block is easily removed from the Voltage Sensor Adapter for convenien t wire
termination.

3. Connect a 18-24AWG CAT5/5e/6 patch cable (up to 1,000 feet long) between the “Cat 5” port on the Voltage Sensor Adapter
and an “RJ45 Sensor” port on the SYSTEM. (The use of smaller gauge CATx cabling will result in shorter distances that can be
spanned.)
Note: Each row of RJ45 Sensor connectors (1-8 and 9-16) is rated for a combined load of 500mA. Each
E-S5VDC uses 100mA. When applying sensors, be sure that the total load on each row does not exceed 500mA or
failure of the SYSTEM or may result.
4. Configure the SYSTEM to react to changes in the voltage from the source, as desired. See example on page 4.

INSTALLATION NOTE FOR E-AV-K AIR VELOCITY SENSOR
Correct positioning the E-AV-K Air Velocity Sensor is critical for reliable and accurate readings of air velocity in ducts. The Air
Velocity sensor should be placed far enough from sources of air turbulence in the duct. The minimum distance the sensor should
be placed from the source of turbulence is a function of the duct's diameter.
