SIEMENS 9810 Series Advanced Power Quality Meter

Product Information

The 9810 series is a meter base device manufactured by Siemens. The device has several options including US2:9810TC, US2:9810RC, US2:9810BBADAPTER, US2:9810R7DISP, and US2:9810PMHWK. The device has an ambient temperature specification which should be followed during installation. The device has voltage inputs, control power, digital inputs, Ethernet switch/hub, and RS485#1 and RS485#2 connections. The device also has a relay #1 and relay #2 which can be used for control purposes.

Product Usage Instructions

Before working on the device or equipment, turn off all power supplying the device and the equipment in which it is installed. Always use a properly rated voltage sensing device to confirm that all power is off. Install the meter in an area where the ambient temperature is maintained according to the temperature specification. Leave space for wiring and access. Adding option modules will increase meter base dimensions. The device has several connections including voltage inputs, control power, digital inputs, Ethernet switch/hub, and RS485#1 and RS485#2 connections. The device also has a relay

1 and relay #2 which can be used for control purposes. Refer to the product

manual for detailed instructions on how to properly connect and use these features.

Safety precautions

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Failure to follow these instructions will result in death or serious injury.

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E in the USA or applicable local standards.
• Turn off all power supplying this device and the equipment in which it is installed before working on the device or equipment.
• Always use a properly rated voltage sensing device to confirm that all power is off.
• Do not exceed the device’s ratings for maximum limits.
• Do not use this device for critical control or protection applications where human or equipment safety relies on the operation of the control circuit.
• Never short the secondary of a voltage transformer (VT).
• Never open circuit a current transformer (CT).
• Always use grounded external CTs for current inputs.
• Treat communications and IO wiring connected to multiple devices as hazardous live until determined otherwise.

1. Turn off all power supplying this device and the equipment in which it is installed before working on the device or equipment.
2. Always use a properly rated voltage sensing device to confirm that all power is off.

Mounting considerations

Install the meter in an area where the ambient temperature is maintained according to the temperature specification. Leave space for wiring and access.

Wiring diagrams

Bottom

Straight-line topology shown. RSTP must be enabled for loop or ring topology.

• A 2 A fuses and disconnect switch
• B Shorting block
• C VT primary fuses and disconnect switch

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. Meter must be configured for specified volts mode.

3PH Voltage

• Volts mode = DELTA
• Volts mode = 4W-WYE
• Volts mode = 3W-WYE

1PH Voltage and current

• Volts mode = SINGLE

3PH Current

Control power

D 2 A fuses

• 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.
