Chapter 1 Product Introduction
1.3 Safety Precautions
Installation Notes Install the power meter according to instructions on the manual. Use appropriate personal protective equipment (PPE) and follow safe electrical work practices. Only qualified electrical workers should install this equipment. Such work should be performed only after reading the entire set of installation instructions. Operate the power meter according to instructions on the manual. Neglecting fundamental installation requirements may lead to personal injury as well as damage to electrical equipment or other property. This equipment should be installed in a suitable insulated and fireproof enclosure.
Operation Notes
DO NOT work alone. Before performing visual inspections, tests, or maintenance on this equipment,
disconnect all electric power sources. Always use a properly rated voltage sensing device to confirm that power is off. Replace all devices, doors and covers before turning on power to this equipment. Carefully inspect the work area for tools and objects that may have been left inside
the equipment.
Operation Notes Never short the secondary of a Power Transformer (PT). Never open circuit a Current Transformer (CT) Ensure that the CT secondary winding is fixed securely on the equipment. It may damage the equipment if the secondary winding becomes loose during operation. When used with CTs, make sure the CTs are UL2808 listed in America and Canada and meet or exceed the accuracy specifications for IEC61869-2 class or accepted by authority having jurisdiction (AHJ) in other areas.
Wiring Notes When the measured current is higher than the rated specification for the device, consider using an external current transformer (CT). When the measured voltage is higher than the rated specification for the device, consider using an external potential transformer (PT) (line voltage: 35 to 690V AC L-L or phase voltage: 20 to 400V AC L-N, 3P4W-690Y400 Vac / 3P3W-600 Vac). Connect only one cord to one plug on the quick connector. For the device is accidently unplugged, check the connecting cord and restart.

3.2 Basic Checks

Items

Contents

Regularly check for mounting looseness where the power meter and device are

connected.

General Check

Prevent foreign objects, such as oil, water, or metal powder entering the device through the ventilation holes. Prevent drill shavings or other debris entering the power meter.

If the power meter is installed at a location with harmful gas or dust, prevent those

materials from entering the power meter.

Insulate the connections at the wiring terminals.

Communications wiring should be done properly to prevent abnormal operations.

Pre-operation Check

Check for the presence of conducive and flammable objects, such as screws or metal

pieces in the power meter.

(not supplied with power)

If electronic devices near to the power meter experience electromagnetic interference,

take steps to reduce the electromagnetic interference.

Check for the correct voltage level for the power supplied to the power meter.

Pre-running Check if the power indicator light is lit.

Check Check if communication between every device is normal.

(supplied with If there is any abnormal response from the power meter, contact your distributor or our

power)

customer service center.

3.3 Wiring
3.3.1 Wiring Diagrams
To avoid electric shock, do not change the wiring when the power is on. Install a breaker switch on the power cord for the meter because there is no power switch on the power
meter. When the measured voltage is higher than the rated specification for the device, it is necessary to use an
external potential transformer (PT). When the measured current is higher than the rated specification for the device, it is necessary to use an
external current transformer (CT).

The following table shows the recommended wiring materials.

5.2 Modbus Communication

5.2.1 Supported Modbus Function Codes

Function Code
0x03 0x06 0xFE

Modbus Name
Read Holding Registers Preset Single Registers Read Data Log

Description
Read the contents of read location Preset the contents of written location Read the contents of data log

When the protocol is Modbus RTU, the maximum address to be gathered with a single Modbus block read is 50 for function code 0x3, and the maximum address is 49 for function code 0x10. The function code 0xFE can be used only when the protocol is Modbus RTU.

5-7

Delta Din-rail Power Meter DPM-D510 User Manual

5.2.2 Modbus Communication Protocol
Modbus RTU mode is adopted with Modbus Master sending out the Request, in which the Function Code uses 0x03 to request response from Slave to correspond to values in Modbus address. In Response, Modbus Slave responds to the values of Modbus address in the Master request. The packet format of IEEE754 is used for the address of floating point numbers that corresponds to the register values found in table 5.2, using 2’s complement packet format. The format are as follows:

Low Word

High Word

High Byte Low Byte High Byte Low Byte

The packet formats (2’s complement) for the address of integers that corresponds to the register values found in table 5.2 are shown in the example below.

Chapter 5 Parameters and Functions
Write:

Example: For Modbus Master, such as PLC or data collector, it uses Modbus protocol to get the value of CT setting (Register address 0x000E) on the power meter (Modbus Slave) (Slave address 0x1). The register value is 1000. The packet format for Request sent out by Modbus Master (PLC or data collector) is as follows:

_5

The packet format for Response responded by Modbus Slave (power meter) is as follows: 5-9

Delta Din-rail Power Meter DPM-D510 User Manual

_5

After receiving response from the power meter, Modbus Master acquires the value of currents from the primary-side current transformer (register address 0x000E), which is 1000 (0x3E8).

Should Modbus Slave (power meter) receive an abnormal Request, the format of the abnormal packet responded and the error codes are as follows.

Error Code 0x01 0x02 0x03
0x04

Error Name Illegal Function Illegal Data Address Illegal Data Value
Slave Device Failure

Description The function code is illegal. The data address is illegal to read or write. The data format is incorrect, such as wrong data length. Slave cannot execute the command.
