This section summarizes the precautions on conformance to the EMC Directive of the cabinet constructed using this Instrument. However, the method of conformance to the EMC Directive and the judgment on whether or not the cabinet conforms to the EMC Directive has to be determined nally by the manufacturer.

1. EMC Standards EN 61326-1:2006 EN 61000-3-2:2006/A1:2009/A2:2009 EN 61000-3-3:2008

2. Installation (EMC directive) The instrument is to be mounted on panel of a cabinet. Therefore, the construction of a cabinet is important not only for safety but also for EMC. The instrument is examined by the following conditions. Use a conductive cabinet. Six faces of a cabinet have to be ensured conductivity for each other. A cabinet has to be connected to earth by a thick wire of low impedance. Holes on faces of cabinet have to be 10 cm or less in diameter. The terminals for protective earth and functional earth have to be connected to earth by a thick

wire of low impedance. (A terminal for protective earth is important not only for safety but also for EMC.)

Protective earth: Maintains the safety of the instrument and improves the noise resistance. Functional earth: Improves the noise resistance.

All connections should be kept inside the cabinet. Wirings outside the cabinet have to be used with the shielded cable.

The following diagram shows how to provide good contact of the shielded cable. Remove part of the outer cover. Remove part of the paint musk on the cabinet. Connect those parts with the clamp.

5. Operation2. Function Modes

The following function modes are available for this Multi-Measuring instrument. Operation mode is displayed after auxiliary power turns on. It is then possible to switch to the desired mode.

Mode Description Reference

Pages Operation Mode This mode is for displaying each measured value using digital numerical

values and bar graphs. Operation mode contains "Current Value Display" that displays the current value, and "Maximum/Minimum Value Display" that displays old maximum/ minimum values. In addition, for each display, the cyclic display function can be used to switch between the screens every 5 seconds.

P. 47 to P. 57

Setting mode This mode is for changing the setting values related to measurement and output functions. The following special operations can be executed from the "CANCEL Display" for changing/cancelling setting values.

The instrument is reset. Reset the settings to the factory defaults (Note)

P. 12 to P. 32 P. 35 to P. 39

Setting value con rmation mode

This mode is for con rming the setting values for each setting item. (In this mode, settings cannot be changed in order to prevent accidental changing of settings.) This mode contains test functions that can be used for equipment startup.

Incorrect Wiring Determination Support Display : This displays information such as voltage and current phase angle display for determining improper wiring.

Analog Output Adjustment : Analog output can be adjusted (zero adjustment and span adjustment).

Output Test : Analog output can be switched, pulse output can be executed, and alarm contact points can be opened/closed without measurement input (voltage/current).

Communication Test : Fixed numerical data can be returned without measurement input (voltage/current).

3.1 Setting Procedure

To measure, it is necessary to use Setting mode to set the phase wire system, VT / direct voltage, and CT primary current. From Operation mode, move to Setting mode and then set necessary items. Factory default settings will be used for items that you do not set. Only the settings in Setting menu 1 (basic set-up) are needed for normal use. For more information about the settings, refer to the following pages. For more information about the factory default settings, refer to the setting table on page 81.

CAUTION Keep in mind that when a setting is changed, the related setting items and measurement data will be reset to the default settings. (Refer to page 35.)

4. Using Test Mode

Test mode includes functions that can be used for start-up of equipment. The following table shows what can be done in the test mode.

Test menu Description

1. Incorrect wiring determination support display

Displays the phase angle for the current/voltage and active energy/voltage/current for each phase. By confirming each displayed value, it is easier to determine whether there is incorrect wiring at connections for measurement (voltage/current) input.

2. Zero span adjustment for analog output

For functions with analog output, zero span adjustment can be done for analog output. Adjust this when matching with the receiver side and when output changes.

3. Analog output operation test For functions with analog output, it is possible to confirm analog output operation without measurement (voltage/current) input. Use this for confirming connection with the receiver.

4. Pulse output operation test For functions with pulse output, it is possible to confirm pulse output operation without measurement (voltage/current) input. Use this for confirming connection with the receiver.
