1.2 Foreword
Thank you for purchasing the Forlong DRT-370D DIN rail three phase four wire
energy meter. The Forlong DRT-370D energy meter is the most advanced type
electronic kWh meter available at the market. With the Forlong product range we
have introduced a large scale of energy meters on the market suitable for 110V AC
to 400V AC (50 or 60Hz). Besides the normal energy meters we also developed our
own pre-paid meters with chip card, chip card re-loaders and a complete PC
management control system. For more information on other product please contact
our sales department at [email protected] or [email protected].
Although we produce the Forlong DRT-370D meter according to IEC 62053-21 and
our quality inspection is very accurate there might always be a possibility that your
product shows a fault or failure for which we do apologize. Under normal conditions
your product should give you years of benefit and pleasure. In case there is problem
with the energy meter you should contact your dealer immediately. All energy
meters are sealed with a special seal. Once this seal is broken there is no possibility
to claim for warranty. Therefore NEVER open an energy meter or break the seal of
the energy meter. The warranty time is 6 months, after production, and only valid
for construction faults.
