Page 10: Instrument Description
3. Instrument description The EM-PQ 2300 Power Quality Analyzer is a useful addition to the FRAKO range of products. It offers the possibility of carrying out long-term network analyses in compliance with EN 50160 or EN 61000-2-4, monitoring short supply network sags and performing TN-S system measurements. Harmonics up to the 51st are measured. -
Page 11: Mounting The Instrument
(office and residential area) will be complied with. The EM-PQ 2300 Ethernet connection is at the top of the casing. A free space of at least 50 mm must be allowed above the EM-PQ 2300 because of the minimum allowable bending radius of the Ethernet cable and the type of connector used. -
Page 12: Installation
We recommend keeping cable lengths as short as possible and using shielded cables or possibly absorber cables. It can happen that the EMC emission limits are exceeded if the EM-PQ 2300 is used in combination with other devices. 5.1 Electrical connections... - Page 13 A disconnecting device, such as an isolator or circuit breaker, must be fitted in the building electrical installation in a suitable location, accessible by the user and appropriately labelled as a disconnecting device for the EM-PQ 2300. It must be able to isolate all cables operating at the power supply voltage from the instrument.

Page 15: Instrument Power Supply
- An external disconnecting device, such as an isolator or circuit breaker, must be fitted in the power supply line to the instrument. This must be located in the vicinity of the EM-PQ 2300 and must be able to isolate both the L1 and N cables. It must be suitable for this application, comply with the requirements of IEC 60947-1 and IEC 60947-3, and be appropriately labelled as a disconnecting device for the EM-PQ 2300. -
Page 16: Current Measurements
Lx must have a completely different colour! If this is not ensured, it is possible that the terminal Lx on the EM-PQ 2300 may then be mistaken for a normal PE connection, and an additional earth conductor could be commoned there as well. - Page 17 These measures must be taken to ensure that the instrument is not damaged. The EM-PQ 2300 can measure five AC currents, whose respective inputs are electrically isolated from each other. See Section 2, Technical data, page 7 for the measurement ranges.

Page 18: Ethernet Connection
5.1.3 Ethernet connection The EM-PQ 2300 has a shielded RJ45 jack at the top for connecting it to a hub or switch. Its pole assignment corresponds to an MDI interface, so that a 1:1 cable must be used; Category 5 is adequate. -
Page 19: Display Bus
The bus shielding ( ) must be earthed at one point in the bus system. If earthing has not already been done at some other point, it can be done at the EM-PQ 2300. However, the bus must only be earthed at one point! If this is not done, damage can occur to the bus interfaces of all connected devices, and data transmission can be disrupted. -
Page 20: Requirements For The Bus Cabling
EM-FD 2500 Displays may be connected to the same bus segment, however no more than one EM-FD 2500 Display per EM-PQ 2300 or EM-MC 2200 may be connected. If these instructions are not complied with, data transmission may be disrupted. It is also possible that no functioning data link can be established between the devices. -
Page 21: Number Of Devices On The Display Bus
5.1.5.4 Terminating resistors A terminating resistor must be in the circuit at each end of the bus. With the EM-PQ 2300, this is done with the configuration switch 1 (DIP switch 1). When this rocker switch is pressed down towards the base of the instrument, the internal terminating resistor is switched in, otherwise the resistor is not in the circuit. -
Page 22: Temperature In
EM-PQ 2300 or other devices connected to it. 5.1.9 Temperature IN The EM-PQ 2300 has one temperature input, to which either a Pt100 or a Pt1000 RTD probe can be connected. The EM-PQ 2300 automatically identifies the type of probe connected, 2-wire or 4-wire configuration being possible. -

EM-PQ 2300 started up 6.2 Functional checkout When the power is switched on, the Run LED lights up. After about 20 seconds, the EM-PQ 2300 is ready to operate and the Run LED starts flashing at 1-second intervals. -
Page 24: Dhcp Options
All FRAKO devices that can be operated on the Display bus are provided with an internal terminating resistor that can be switched in and out. With the EM-PQ 2300, this is done with the configuration switch 1 (DIP switch 1). -

Page 35: Maintenance
Maintenance Operating Manual EM-PQ 2300 9. Maintenance Except for the lithium battery installed in the EM-PQ 2300, the instrument does not need any maintenance. DANGER! The following instructions must be observed to avoid danger to life and limb: The instrument casing must not be opened. Exception: Opening the cover as described in Section 9.2 Battery, page 35, and in Section 9.3 , page 36. -
Page 36: Fuse
Observing the above safety precautions can significantly reduce the risk to life and limb. An internal fuse is fitted in the EM-PQ 2300. It is mounted in a fuseholder underneath the hinged cover printed with the instrument name. This cover can be opened downwards once the four tabs at the top edge of the cover have been carefully released. -
