The RMA 3000, Models RMA300, SM & ME Remote Meter Assemblies are
intrinsically safe apparatus that can be installed in potentially explosive atmospheres.
The power terminals (+, -) must be connected only to a certified associated
intrinsically safe apparatus.
The electrical parameters (U, I, and P) of the associated apparatus connected to the
power terminals (+, -) must not exceed the following values:
Ambient temperature: - 20ºC to 60ºC
Temperature classification: T5 up to Ta ≤ 60ºC
Power supply to field wiring terminals, + and –: Ucc ≤ 42 V
Output Signal: 4 – 20 mA
Ambient operating temperature: -20 to 65ºC
Supply Voltage:
Supply Current:
Ambient Temperate Limits:
Temperature Classification:
• The installation of this equipment in Zone 2 hazardous areas must comply with
VDE specification 0165, IEC 60079-14, EN 50021 and/or valid national standards
for installation and operation.
Before commissioning of this equipment, it must be verified that the power supply
•
voltage cannot exceed the 42 Vdc maximum for 4-20 mA analog and DE and
Smart meters.
• The electronic assemblies in these units are non-repairable items and if faulty must
be replaced. The electrical power supply must be switched off before any
replacement and during any time that the wiring terminations are being connected
or disconnected.
