Product Usage Instructions

• Read the safety instructions carefully before using the product.
• Use only isolated tools and do not connect the circuit while it is live (hot).
• Ensure that the wires used are suitable for the maximum current of the meter.
• Make sure the AC wires are connected correctly before activating the current/voltage to the meter.
• Do not touch the meter connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electrical shock.
• Installation, maintenance and reparation should only be done by qualified personnel.
• Do not drop or allow physical impact to the meter as there are high-precision components inside that may break.

Safety instructions

Information for Your Own Safety
This manual does not contain all of the safety measures for operation of the equipment (module, device), because special operating conditions, and local code requirements or regulations may necessitate further measures. However, it does contain information which must be read for your personal safety and to avoid material damages. This information is highlighted by a warning triangle and is represented as follows, depending on the degree of potential danger.

Warning
This means that failure to observe the instruction can result in death, serious injury or considerable material damage.

Caution
This means hazard of electric shock and failure to take the necessary safety precautions will result in death, serious injury or considerable material damage.

Proper handling

Troubleshooting

CAUTION

• During reparation and maintenance, do not touch the meters connecting clamps directly with your bare hands, with metal, blank wire or other material as you will have the chance of an electricity shock and a possible chance for health damage.
• Turn off and lock out all power supplying the energy meter and the equipment to which it is installed before opening the protection cover to prevent the hazard of an electric shock.

WARNING

• Maintenance or reparation should be performed by qualified personnel familiar with applicable codes and regulations.
• Use insulated tools to maintain or repair the meter.
• Make sure the protection cover is in place after maintenance or reparation.

**** Is the operating power too low?

**** Maybe there is a fault in the inside circuit.

| Only when load is running, this LED will flash.

**** If the operating power is too low, the spacing interval of the flashes will take some more time this is why it seems like LED is not burning

Please contact your technical supporter to replace this meter.

The register can’t

run.

| Is the operating power too low?

Maybe there is a fault in the inside circuit.

| If the operating power is too low, the spacing interval of the pulses will take some more time this is why it seems like the meter won’t count

**** Please contact your technical supporter to replace this meter.

Pulse output rate wrong.| Maybe there is a fault in the inside circuit.| Please contact your technical supporter to replace this meter.
