Device short description and assembly

The device is a multifunctional power analyzer that

measures and calculates electrical parameters, such as voltage, current, frequency, power, energy and harmonics, etc. in building installations, on distributors, circuit breakers and busbar trunking systems.
displays and saves measurement results and transfers them via interfaces.

ATTENTION
Property damage due to noncompliance with the assembly instructions
Noncompliance with the assembly instructions can damage or destroy your device.

Ensure sufficient air circulation in your installationenvironment and,where applicable, sufficient cooling with high ambient temperatures.
You can find more detailed information about the device functions, data, assembly in the device in the user manual.

Mount the measurement device in switch cabinets or small distribution boards according to DIN 43880 (any installation position) on a 35 mm (1.38 in) DIN rail, as follows:

Connecting the supply voltage

The supply voltage level for your device can be found on the rating plate or in the technical data. After connecting the supply voltage, a display appears. If no display appears, check whether the supply voltage is within the rated voltage range.

ATTENTION
Property damage due to noncompliance with the connection conditions or impermissible overvoltages
Noncompliance of the connection conditions or exceeding the permissible voltage range can damage or destroy your device.
Before you connect the device to the supply voltage, please observe the following:

The voltage and frequency must comply with the specifications on the rating plate. Observe the limit values as described in the user manual.
In building installations, secure the supply voltage with a UL/IEC-listed circuit breaker/fuse.
The circuit breaker
– must be easily accessible for the user and located in the vicinity of the device.
– must be labeled for the respective device.
Do not tap the supply voltage at the voltage transformers.
Provide a fuse for the neutral conductor if the neutral conductor connection is not grounded to the source.

Network systems

Suitable network systems and maximum rated voltages (DIN EN 61010-1/A1):

Application areas of the device:

3 and 4 conductor networks (TN, TT and IT networks).
Residential and industrial sectors.

Voltage/Current measurement

The device

has 4 voltage inputs
measures current exclusively via a current transformer.
permits connection of current transformers with a transformer ratio of ../1 A and ../5 A
does not measure DC currents.

The current transformers require basic insulation according to IEC 61010-1:2010 for the rated voltage of the circuit.

WARNING
Risk of injury or damage to the device due to electrical voltage and improper connection!
Disregard of the conditions for the connections of the voltage and current measurement inputs may damage the device or cause serious injury or death. Connecting the voltage lines to the current measurement inputs also poses a fire hazard!
Therefore please abide by the following:

Switch off your installation before commencing work! Secure it against being switched on! Check to be sure it is de-energized! Ground and short circuit! Cover or block off adjacent live parts!
Check the condition of the connections, including the cabling, especially the connection of the voltage and current measurement.
Do not apply a DC voltage
– to the voltage measurement inputs.
– Equip the voltage measurement inputs with a suitable, marked fuse and isolation device (alternatively: line circuit breaker) located nearby.
– The voltage measurement inputs are dangerous to touch.
Connect voltages that exceed the permissible nominal network voltages via a voltage transformer.
Measured voltages and currents must originate from the same network.

WARNING
Risk of injury due to high currents and high electrical voltages!
Serious personal injuries or death can occur due to:

Touching live exposed or stripped cores.
Device inputs that are dangerous to touch.

Therefore, please observe the following for your system:

Before starting work, disconnect it from the power supply!
Secure it against being switched back on!
Verify disconnection from power!
Ground and short circuit! Use the ground connection points with the ground symbol for grounding!
Cover or block off neighboring parts that are under voltage!

WARNING
Electrical currents and voltages!
Open current transformers that are operated on the
secondary side (high voltage spikes) can result in serious personal injuries or even death.
Avoid the open operation of the current transformers and short-circuit unloaded transformers.

Establishing the connection to the PC

The most common connections for the communication between the PC and device:

CAUTION
Property damage due to incorrect network settings.
Incorrect network settings can cause faults in the IT network!
Consult your network administrator for the correct network settings for your device.
Example: PC connection via RS485 interface and UMG 604 as the gateway
The PC connection to the device via the RS485 serial interface with, e.g. a UMG 604 as the gateway (see section “Establishing the connection to the PC”) is a method for configuring the device(s)/and reading out data.
RS485 bus structure

Connect all devices in the RS485 bus structure (line) according to the master/slave principle.
A segment of a RS485 bus structure can contain up to32 participants/devices.
Terminate the cable with termination resistors (120 Ω, 0.25 W) at the beginning and end of a segment. The device does not contain a termination resistor.
With more that 32 participants, use repeaters to connect segments.
Further information, e.g. Cable type, refer to the user manual.

ATTENTION
Using the corresponding menu items, assign the slave devices in the RS485 bus structure

Different device addresses.
