INSTALLATION AND START-UP

The manual you hold in your hand contains information and warnings that the user should respect in order to guarantee a proper operation of all the instrument functions and keep it in safety conditions. The instrument must not be powered on and used until its definitive assembly is on the cabinet’s door.

If the instrument is not used as manufacturer’s specifications, the protection of the instrument will be damaged.
When any protection failure is suspected to exist (for example, it presents external visible damages), the instrument must be immediately powered off. In this case contact a qualified service representative.

Installation

Mounting
Instrument is to be mounted on 35mm Din-rail. Keep all connections into the cabinet. Please note that with the instrument powered on, the terminals could be dangerous to touch and cover opening actions or elements removal may allow accessing dangerous parts. Therefore, the instrument must not be used until this is completely installed.

Notes :
Input signal: 19D-22D using a separate acquisition calculate for each measurement channel, to ensure consistent in use, for different load forms, it’s a variety of connection mode. Access wire shall be met 3 square mm.

• Voltage input
  Input voltage should not exceed the rated input voltage products 450V.
  Otherwise, you should use external VT. Suggest 1A fuse be installed in the voltage input side.

• Current Input
  Standard input current is 5A or 1A, if greater than 5A/1A should use external CT.
  When the CT is connected with other meters, make sure wiring methods be used in series.
  Warning: Forbid to install a CT on the live feeder wire with open secondary leads. This can be extremely dangerous!
  Before remove the current input connection, must be sure to disconnect the primary circuit or shorted secondary circuit of CT.

• equence of wire

  • Warning: Please make sure that the input voltage and current corresponding to the same phase, sequence, and the same direction; Otherwise, the Values and symbols will be wrong! (Power and Energy)
  • Always observe the physical orientation of CT (P1 – P2) when installing on the feeder wire. Always pay attention to wiring polarity and phasing when terminating the CT leads to the 19D-23C. S1 connect to Ix*, S2 connect to Ix.
  • The input network configuration of instrument depends on the CT number of the system:
  • in the condition of 2 CT, select the three-phase, three-lines two components;
  • in the condition of 3 CT, select the three-phase, four-lines three component mode.
  • Instrument connection mode, set of the instrument (programming input network NET) should be the same load wiring as measured wiring. Otherwise, the measurement instrument will lead to incorrect voltage or power.

• Auxiliary power
  19D-22D with universal (AC / DC) power input, if not for a special statement, we provide the 90-240AC/DC power interface for standard products, please ensure that the auxiliary power can match with meter to prevent unexpected damage.

  • Suggest install 1A fuse in the fire line side.
  • For the areas with poor power quality, suggest install lightning surge suppressor and rapid burst suppressor to prevent lightning strikes.

FAQ’s

1. Once cabled and connected is seen to give a correct voltage and current reading, but shows negative values for active power (generation).
   This is an error with the cabling for the current transformer secondary; the direction of the transformer current has to be respected as shown in the connection diagram. The current transformers have a two face primary; the current must pass from P1 to P2 giving the result in secondary (S1 and S2) of 5 amps.
   The error stems from:

   • The current transformers have been incorrectly installed. As a result, it gives the direction  of the current as passing from P2 to P1; to resolve this problem, the current transformer does not have to be dismantled and installed again, but the transformer secondary (S1 and S2) just has to be inverted.
   • The connection of the current secondary in the current transformers have been incorrectly connected; to resolve this problem just connect the S1 transformer secondary to the S1  on the meter and the S2 on the current transformer to the S2 on the meter.

2.  Once cabled and connected, is seen to give an incoherent Power factor and CosΦ reading (-
   0.01 or similar).
   This is again a current transformer and voltage phase connection error phase A, must correspond to the current transformer installed in phase A; phase B, must correspond to the current transformer installed in phase B; and phase C, must correspond to the current transformer installed in phase C.
   This connection terminal is clearly shown on the area side of the device.

3. The measuring voltage and is displaying the secondary voltage (for example 110 volts).
   Ensure that the voltage Transformer ratio has been correctly set.

4. Device does not correctly display the current reading. It shows values varying between 0 to 5 amps of current.
   Ensure that the Current Transformer ratio has been correctly set.
