RMA805 Enraf FlexLine Remote Indicator Quick Start Guide
5
A2 Marking ATEX Directive
a.
General
The following information is provided as part of the labeling of the Remote Indicator:
Name and Address of the manufacturer
The serial number of the Remote Indicator is located on the Meter Body data-plate. The
first two digits of the serial number identify the year (12) and the second two digits identify
the week of the year (23); for example, 1223xxxxxxxx indicates that the product was
manufactured in 2012, in the 23rd week.
b.
Apparatus Marked with Multiple Types of Protection
The user must determine the type of protection required for installation the equipment. The
user shall then check the box [ ] adjacent to the type of protection used on the equipment
certification nameplate. Once a type of protection has been checked on the nameplate, the
equipment shall not then be reinstalled using any of the other certification types.
c.

WARNING – OPEN CIRCUIT BEFORE REMOVING COVER
All Protective Measures:
WARNING: FOR CONNECTION IN AMBIENTS ABOVE 60°C USE WIRE RATED 105°C
A.3 Conditions of Use” for Ex Equipment”, Hazardous Location Equipment or
“Schedule of Limitations”:
a.
Consult the manufacturer for dimensional information on the flameproof
joints for repair.
b.
Painted surface of the RMA 800 series may store electrostatic charge and
become a source of ignition in applications with a low relative humidity less
than approximately30% relative humidity where the painted surface is
relatively free of surface contamination such as dirt, dust or oil. Cleaning of
the painted surface should only be done with a damp cloth.
c.
The ambient temperature range and applicable temperature class of the
equipment is as follows:
RMA800 series: T4 for -
20˚C < Ta < 70˚C
d.
The RMA800 series enclosure contains aluminum and is considered to
present a potential risk of ignition by impact or friction. Care must be
considered during installation and use to prevent impact or friction to avoid
impact.
e.
If a charge-generating mechanism is present, the exposed metallic part on
the enclosure is capable of storing a level of electrostatic charge that could
become incendive for IIC gases. Therefore, the user/installer shall
implement precautions to prevent the buildup of electrostatic charge, e.g.
earthing the metallic part. This is particularly important if the equipment is
installed in a zone 0 location.
f.
On installation, the RMA800 series shall be provided with supply transient
protection external to the apparatus such that the voltage at the supply
terminals of the RMA800 series does not exceed 140% of the voltage
rating of the equipment. However when an RMA805 is connected to a
SmartRadar FlexLine or to a SmartServo 954 the supply transient
protection is included in the SmartRadar FlexLine or SmartServo 954.
