In Case of Fire or Other Emergency
In all cases:
•
If safe to do so, switch off the AC breaker for the IQ
TM
Battery circuit, and if
an isolator switch is present, switch off the AC isolator for the IQ
TM
Battery
circuit.
•
Contact the re department or other required emergency response team.
•
Evacuate the area.
In case of re:
•
When safe, use a re extinguisher. Suitable types are A, B, and C dry chemical
re extinguishers. Additional extinguishing media include carbon dioxide, or
alcohol-resistant foams.
In case of ooding:
•
Stay out of the water if any part of the IQ
TM
Battery(ies) or wiring is
submerged.
•
If possible, protect the system by nding and stopping the source of the
water, and pumping it away.
•
If water has contacted the battery, call your installer to arrange a inspection.
If you are sure that water has never contacted the battery, let the area dry
completely before use.
In case of unusual noise, smell or smoke:
•
Ensure nothing is in contact with the IQ
TM
Battery(ies) or in the venting area
of the IQ
