Rish ED 1111 Installation Manual

Single Phase Direct connected Energy Meter Din Mount 1U Installation Guide
The Direct Connected Energy Meter is a DIN Rail mounted Digital Meter, primarily for bidirectional
Active, Reactive and Apparent Energy measurement intended for use in industrial, commercial and
residential electrical energy metering. It also accurately measures important electrical parameters
like TRMS Voltage, TRMS Current, Frequency, Active / Reactive and Apparent Power, and Power
Factor in Single Phase Networks. The meter is engineered using advanced microcontroller techno-
logy and is suitable for electrical parameter measurement and monitoring in 1 Phase 2 Wire
Networks. It supports maximum 45 A current measurement on direct connection. It displays
parameters on bright intuitive LCD and also has Pulse Outputs and Impulse LED for energy
monitoring. It supports Tariff Counters selectable via MODBUS Communication as per model. It has
inbuilt industry standard MODBUS RTU for remote monitoring.
Safety Precautions:
All safety related codifications, symbols and instructions that appear in this operating manual or on
the equipment must be strictly followed to ensure the safety of the operating person as well as the
instrument.
If the equipment is not used in a manner specified by the manufacturer it might impair the protection
provided by the equipment.
Do not use the equipment if there is any mechanical damage.
Ensure that the equipment is supplied with correct voltage.
1. Read complete instructions prior to installation and operation of the unit.
2. Risk of electric shock.
3. The equipment in its installed state must not come in close proximity to any heating sources, oils,
steam, caustic vapors or other unwanted process by products.
4. Circuit breaker should be installed and preferably near equipment so that in case of hazards can
be accessed easily for switching off the mains.
Wiring Guidelines:
1. To prevent the risk of electric shock, power supply to the equipment must be Kept OFF while doing
the wiring arrangement.
2. Wiring shall be done strictly according to the terminal layout. Confirm that all connections are
correct.
3. Use lugged terminals.
4. To reduce electromagnetic interference use of wires with adequate ratings and twists of the same
in equal size shall be made with shortest connections.
5. Layout of connecting cables shall be away from any internal EMI source.
6. Cable used for connection to power source, must have across section of 10 mm
These wires shall have current carrying capacity of 45A.
7. Copper cable should be used (Stranded or Single core cable).
8. Before attempting work on device, ensure absence of voltages using appropriate voltage
detection device.
9.Use the wire sizes and tightening torque as listed below
2
Current input wire size 10mm
Tightening torque 0.5Nm
2
RS485/SO wire size 0.1 to 2.5 mm (Solid/Stranded with pin type lug)
Tightening torque 0.3 to 0.4 Nm.
Installation Guidelines
1. This equipment, being normally becomes a part of main control panel and in such case the
terminals do not remain accessible to the user end after installation and internal wiring.
2. Conductors must not come in contact with the internal circuitry of the equipment or else it may
lead to a safety hazard that may in turn endanger life or cause electrical shock to the operator.
3. The equipment shall not be installed in environmental condition other than those mentioned in this
manual.
4. Connector screw must be tightened after installation.
5. Enclosure is IP51 front and IP20 at terminals and to be used in indoor installations only
