26 AQUAMASTER4 | ELECTROMAGNETIC FLOWMETER TRANSMITTER | OI/FET400-EN REV. D
…5 Installation
Battery power supply
IMPORTANT (NOTE)
• The external earthing (grounding) boss must be
connected to an earthing (grounding) rod.
• Observe all warnings in Battery hazard, handling,
shipping and recycling/disposal on page 6.
• Never remove the transmitter lid assembly when
the water level around the flowmeter is close to the
enclosure.
• Only use 3.6 V lithium thionyl chloride D batteries
recommended by ABB.
Recommended/preferred batteries are:
– SAFT LS33600
– Eve ER34615
– GB Cell ER34615
– cT-energy ER34615
– OmniCel ER34615
– GEBC ER34615
– LiYa ER34615
– Fanzo ER34615H
The above batteries comply with the safety
requirements of IEC60086-4 and have a maximum
peak discharge current of less than 500mA.
Connect the external earth (ground) boss to the local electrical
earth, cabinet earth, or earth rod if no electrical earth is
available. Use a suitable wire with a cross sectional area rated
for >3 A.
