The digital outputs are not intended for use within primary protection circuits. Vecto III is intended for indoor installation and use only. If it is required for use in an outdoor environment, then it must be mounted in a specific cabinet or housing which will enable it to meet the requirements of IEC 60529 with the classification of degree of protection IP52.
1.4 How to Mitigate Risks 1.4.1 Always earth the device first It is recommended to always earth the device first before making any other electrical connections. This ensures the device casing to be at the same potential of the safety environment and will eliminate the risk of electric shock.
It is a single feeder device, as opposed to the dual feeder Impedo DUO, and has 4 x voltage, 4 x current sensor and 4 x powered current transducer inputs. The Vecto III has an on-board GPS, 2 x Gigabit Ethernet ports, a USB2.0 (HS) expansion port, 4 x digital inputs (5V power available) and 4 x digital outputs.
If the shipment is damaged or not in a working condition, please take a picture of the damage and send the pictures to info@ctlab.com as soon as possible. Please also phone CT LAB on +27 (21) 880 9915 to handle the problem as soon as possible. 2.2.2 Unpacking the goods Step...

Vecto III External Interfaces 2.3.2.1 Voltages The voltage inputs to the Vecto III interface directly to 110 V VT circuits or directly to a mains connection, which has to be less than 600 V line to neutral. • Voltage measurements are differential.
2.4.13 for more information. The remote support software supports automatic service discovery protocols. Laptops, when connected to the Vecto III, will receive an IP from the device. The remote support software can automatically discover which devices are connected to the local network.
The 1/6 Sense The Vecto III calculates a complete set of 1-cycle sliding RMS and fundamental phasor parameters on each of the 3 voltage phases resulting in a resolution of 6 values per cycle per phase. The IEC 61000-4-30 Class A requirements are based on a ½ cycle sliding approach.
Clock synchronised parameters are time-stamped with a 1 second time resolution. 2.3.12 Synchrophasors The Vecto III is also a phasor measurement recorder. Recording of 50 Hz (or 60 Hz) synchrophasors can be activated in the configuration setup. Please refer to the Osprey Lite user manual for more information.

2.4.3 Power Supply The Vecto III can be powered and charged directly from mains (90 – 300 V AC/DC) via a power factor corrected internal power supply. The Vecto III can also be powered and charged via an IEEE 802.3-2008 compliant Power over Ethernet (PoE) power supply.
The supply current is power factor corrected and the maximum power consumption of the Vecto III is actively limited to 12.5 VA. The Vecto III can be powered directly from 110 V 50/60 Hz VT circuits due to this low burden.
Vecto III will automatically disconnect from mains if excessive current is drawn from the universal AC/DC supply input port. When this protection was activated, it needs a few minutes to cool, during which the Vecto III will not restart even with valid mains voltage.
2.4.4 Voltage Inputs The Vecto III has 4 resistive differential voltage inputs made up of 6 terminals. The first 4 terminals are used for 3 voltage inputs. V and V are Neutral (V referenced (V -N, V -N, V -N).
2.4.5 Current Inputs The Vecto III has 4 galvanically isolated resistive current shunt inputs with input impedance of 20 m and a full-scale measurement range of 6 A AC-RMS Resistive shunts provide excellent AC and DC response; zero offset drift and very low temperature drift.

2.4.7 Relay Outputs Four digital relay outputs (100 mA , 350 V ) are used to provide digital output AC-RMS AC-RMS information or to control external processes. The outputs are arranged into 2 galvanically isolated clusters (1 kV isolation); each containing a switch contact. The relay outputs are on an 8-terminal lockable connector plug with screw terminals.
2.4.8 Digital inputs The inputs are arranged into two clusters (1 kV isolation); each containing two digital inputs (300 V max) and a 5 V power source with a common. These inputs can be used to attain information like breaker position or disturbance information that can be added to the PQ events/data.
The female SMA port is used to interface an external powered (+3V3) GPS antenna to the Vecto III. The built-in GPS is used to measure absolute time. The Vecto III locks its internal clock to within 1µs from absolute time.
2 IEEE 802.3-2008 compliant Power over Ethernet (PoE) is available on both Ethernet ports. The PoE capability enables the Vecto III to be powered through the communication infrastructure. The Vecto III will therefore be available at all times while the communication infrastructure stays on-line.
2.4.13 Built-in GPRS Modem (Optional) The Vecto III can be shipped with a built-in modem (see Figure 20). Please refer to the Osprey Lite user manual for instructions on configuring modem communication. Before enabling the modem, first ensure that the modem antenna is connected, as enabling the modem without the antenna connected may cause damage to the device.
RTC, the PDU and the health sensors are powered. When the Vecto III will not be used for an extended period of time it can be put into storage mode. To place the device is in storage mode the Power button is toggled off (not depressed).
After power cycling the device with the Power Button, the RTC is in an undefined state – the PQ recording system will require a valid time source after power up before it can function correctly 3.3 Interpretation of Status LEDs Name Function Power...

IP address from a DHCP server. The factory default is for the Vecto III to get an IP address from a DHCP server. For security reasons, the HMI in factory default state is not enabled. To enable the HMI, insert the USB key shipped with the meter into its USB port and wait 30 seconds before attempting to connect.
Export: Download measured data 3.6.2 HMI User Documentation To ensure the Vecto III HMI user documentation stays up to date, the documentation is built into the interface. User documentation can be accessed on the relevant pages by clicking on the icons.
3.7.2 Recovery conditions The Vecto III continuously performs internal health checks. Should one of these checks fail, the device will attempt to recover itself. In case the battery voltage or temperature readings exceed operating limits, the device will perform a controlled shutdown which is indicated by an orange Status LED.
