Direct connect voltage limits

This section outlines typical requirements for wiring the voltage and current inputs of the meter to the electrical power system.

For wiring instructions and safety precautions, see the meter installation sheet that was shipped with your meter, or download a copy at www.schneider-electric.com.

You can connect the meter’s voltage inputs directly to the phase voltage lines of the power system if the power system’s line-to-line or line-to-neutral voltages do not exceed the meter’s direct connect maximum voltage limits. The meter's voltage measurement inputs are rated by the manufacturer for up to 400 V L-N / 690 V L-L. However, the maximum voltage allowed for direct connection may be lower, depending on the local electrical codes and regulations. In US and Canada the maximum voltage on the meter voltage measurement inputs may not exceed 347 V L-N / 600 V L-L.

If your system voltage is greater than the specified direct connect maximum voltage, you must use VTs (voltage transformers) to step down the voltages.

Voltage and current input wiring

For wiring instructions and safety precautions, see the meter installation sheet that was shipped with your meter, or download a copy at www.schneider-electric.com.

Voltage input protection

The meter’s voltage inputs must be wired to fuses/breakers and a disconnect switch. If using a voltage transformer (VT), both primary and secondary sides of the VT must be wired to fuses/breakers and disconnect switches.

• Clearly label the device’s disconnect circuit mechanism and install it within easy reach

of the operator.

• The fuses / circuit breakers must be rated for the installation voltage and sized for the

available fault current.

• Fuse for neutral terminal is required if the source neutral connection is not grounded.

See the meter installation sheet for fuse ratings.

Current input protection

For all connected current inputs, use a CT shorting block to short-circuit the secondary leads of the CTs before removing the current input connections to the meter.

NOTE: Ground any unused current inputs.

PowerLogic™ PM5100 series user guide Chapter 3—Hardware Reference

Balanced system considerations

In situations where you are monitoring a balanced 3-phase load, you may choose to connect only one or two CTs on the phase(s) you want to measure, and then configure the meter so it calculates the current on the unconnected current input(s).

NOTE: For a balanced 4-wire Wye system, the meter’s calculations assume that there is

no current flowing through the neutral conductor.

Balanced 3-phase Wye system with 2 CTs

The current for the unconnected current input is calculated so that the vector sum for all three phase currents equal zero.

Balanced 3-phase Wye or Delta system with 1 CT

The currents for the unconnected current inputs are calculated so that their magnitude and phase angle are identical and equally distributed, and the vector sum for all three phase currents equal zero.

NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or

center-tapped open Delta systems.

Control power wiring

Communications

Serial communications

For wiring instructions and safety precautions, see the meter installation sheet that was shipped with your meter, or download a copy at www.schneider-electric.com.

The meter can be powered from an AC or DC power source.

• L1 and L2 are non-polarized. If using an AC power supply with neutral, connect

neutral to the meter’s L2 terminal.

• Always use a fuse on L1. Fuse L2 when connecting an ungrounded neutral to the

control power.

• If using a control power transformer, fuse both primary and secondary sides of the

transformer.

• The fuses / circuit breakers must be rated for the installation voltage and sized for the

available fault current.

This section provides additional information about the communications ports and topologies supported by the meter. You must wire and configure the RS-485 port in order to communicate with the meter.

The meter supports serial communications through the RS-485 port. Up to 32 devices can be connected on a single RS-485 bus.

In an RS-485 network, there is one master device, typically an Ethernet to RS-485 gateway. It provides the means for RS-485 communications with multiple slave devices (for example, meters). For applications that require only one dedicated computer to communicate with the slave devices, an RS-232 to RS-485 converter can be used as the master device.

RS-485 wiring

Connect the devices on the RS-485 bus in a point-to-point configuration, with the (+) and (-) terminals from one device connected to the corresponding (+) and (-) terminals on the next device.

RS-485 wiring

RS-485 cable

Use a shielded 1.5 twisted pair or 2 twisted pair RS-485 cable to wire the devices. Use one twisted pair to connect the (+) and (-) terminals, and use the other insulated wire to connect the C terminals.

RS-485 terminals

Common. This provides the voltage reference (zero volts) for the data plus and data minus signals.

Shield. Connect the bare wire to this terminal to help suppress signal noise that may be present. Ground the shield wiring at one end only (either at the master or the last slave device, but not both).

Data minus. This transmits/receives the inverting data signals.

Data plus. This transmits/receives the non-inverting data signal.

RS-485 maximum cable length

The total distance for devices connected on an RS-485 bus should not exceed 1200 m (4000 ft).

RS-485 network configuration

After you have wired the RS-485 port and powered up the meter, you must configure the serial communications port in order to communicate with the meter.

Each device on the same RS-485 communications bus must have a unique address and all connected devices must be set to the same protocol, baud rate, and parity (data format).

NOTE: To communicate with the meter using ION Setup, you must set the parity to

“None” for all devices in the RS-485 network.

For meters that do not have a display, you must first wire and configure each one separately before connecting these meters to the same RS-485 bus.

Digital outputs

The meter is equipped with a digital output port (D1). You can configure the digital output for use in the following application:

• energy pulsing applications, where a receiving device determines energy usage by

counting the k_h pulses (k_h = kWh, kVARh or kVAh depending on the energy parameter selected) coming from the meter’s digital output port.

The digital output can handle voltages less than 40 V DC. For higher voltage applications, use an external relay in the switching circuit.

Digital output connections

LED indicators

The meter has two LED indicators on the front panel.

Front panel LEDs

Heartbeat / communications LED

The (green) heartbeat / communications LED blinks at a slow, steady rate to indicate the meter is operational. The LED flashes at a variable, faster rate when the meter is communicating over a Modbus serial communications port.

You cannot configure this LED for other purposes.

NOTE: A heartbeat LED that remains lit and does not blink (or flash) indicates a

possible hardware problem. In this case, power down the meter and reapply power. If the LED still does not blink or flash, contact Technical Support.

Alarm / energy pulsing LED modes

The (orange) alarm / energy pulsing LED can be configured for alarm notification or energy pulsing.

Alarm / energy pulsing LED (orange)

Heartbeat / communications LED (green)

• When configured for alarm notification, this LED flashes when a high, medium or

low priority alarm is active. This provides a visual indication of an active alarm condition, or an inactive but unacknowledged high priority alarm.

• When configured for energy pulsing, this LED flashes at a rate proportional to the

amount of energy consumed. This is typically used to verify the meter’s accuracy.
