This symbol, when noted on a product, indicates a potential hazard which could cause serious personal injury and / or death.
The user should reference this instruction manual for operation and / or safety information.
This symbol, when noted on a product enclosure or barrier, indicates that a risk of electrical shock and / or electrocution exists
and indicates that only individuals qualified to work with hazardous voltages should open the enclosure or remove the barrier.
Recycle separately from general waste under the WEEE directive
Electrical equipment marked with this symbol may not be disposed of in European public disposal systems after 12 August
2005. To conform to European local and national regulations (EU Directive 2002/96/EC), European electrical equipment users
must now return old or end-of-life equipment to the manufacturer for disposal at no charge to the user.
ABB is committed to ensuring that the risk of any environmental damage or pollution caused by any of its products is minimized
as far as possible.
Note. For return for recycling, please contact the equipment manufacturer or supplier for instructions on how to return end-of-life
equipment for proper disposal.
The European Union RoHS Directive and subsequent regulations introduced in member states and other countries limits the
use of six hazardous substances used in the manufacturing of electrical and electronic equipment. Currently, monitoring and
control instruments do not fall within the scope of the RoHS Directive, however ABB has taken the decision to adopt the
recommendations in the Directive as the target for all future product design and component purchasing

Warning.
If the transmitter is used in a manner not specified by the Company, the protection provided by the equipment may be impaired.
Remove all power from supply, relay, any powered control circuits and high common mode voltages before accessing or making
any connections. Use cable appropriate for the load currents: 3-core cable rated 3 A and 75 °C (167 °F) minimum, and voltage:
100 / 240 V that conform to either IEC 60227 or IEC 60245, or to the National Electrical Code (NEC) for the US, or the Canadian
Electrical Code for Canada. The terminals accept cables AWG 26 to 16 (0.14 to 1.5 mm2).
Ensure the correct fuses are fitted – see Fig. 6 for fuse details.
Replacement of the internal battery must be carried out by an approved technician only.
The transmitter conforms to Installation Category II of IEC 61010.
All connections to secondary circuits must have insulation to required local safety standards. After installation, there must be no
access to live parts, for example, terminals. Use screened cable for signal inputs and relay connections. Route signal leads and
power cables separately, preferably in an earthed (grounded) flexible metal conduit.
All equipment connected to the transmitter's terminals must comply with local safety standards (IEC 60950, EN61010-1).
The ethernet and bus interface connectors must only be connected to SELV circuits.
USA and Canada Only
The supplied cable glands are provided for the connection of signal input and ethernet communication wiring ONLY.
The supplied cable glands and use of cable / flexible cord for connection of the mains power source to the mains input and relay
contact output terminals is not permitted in the USA or Canada.
For connection to mains (the mains input and relay contact outputs), use only suitably rated field wiring insulated copper
conductors rated min. 300 V, 16 AWG, 90C. Route wires through suitably rated flexible conduits and fittings.
