CAUTION
•
Turn off and lock out all power supplying the energy meter and
the equipment to which it is installed before working on it.
•
Always use a properly rated voltage sensing device to confirm that
power is off.
WARNING
•
Installation should be performed by qualified personnel familiar
with applicable codes and regulations.
•
Use isolated tools to install the meter.
•
We recommend that the connecting wire which is used to connect
the meter to outside circuit should be sized according to local
codes and regulations for the ampacity of the circuit breaker or
over current device used in the circuit.
•
An external switch or a circuit-breaker should be installed on the
inlet wire, which will be used as a disconnection device for the
meter. And there it is recommended that the switch or circuit
breaker be near the meter so that it is convenient for the operator.
The switch or circuit-breaker should comply with the
specifications of the building electrical design and all local
regulations.
•
This meter can be installed indoor directly, or in a meter box
which is waterproof outdoor, subject to local codes and
regulations.
•
To prevent tampering, secure the meter with a padlock or a similar
device.
•
The meter has to be installed in a good ventilated and dry place.
•
The meter has to be installed in a protection box when placed in
dangerous or dusty environments.
•
The meter can be installed and used after being tested and
sealed with a letter press printing.
•
The meter can be installed on a 35mm DIN rail.
•
The meter should be installed in an available height so that it is
easy to read.
•
When the meter is installed in an area with frequent surges due to
e.q. thunderstorms, welding machines, inverters etc, protect the
meter with Surge Protection Devices
•
After finishing installation, the meter must be sealed to prevent
tampering.
•
Connection of the wires should be done in accordance with the
underneath connection diagram.
