MANUAL AQHF12-15 Safety: Power • To reduce the risk of an electric shock, connect only to a properly grounded single phase (3wire) outlet. • Ensure that the AC voltage supplied to the charger is within the ranges in the specification table. Voltages outside this range, particularly high voltages, can result in an electric shock and fire hazard.
MANUAL AQHF12-15 • Do not touch battery terminals or any exposed electrical parts. Contact with battery terminals or other exposed electrical parts may cause an electric shock. Remove all watches, rings, and jewelry to avoid arcing and electric shock. Initial Installation Only trained technicians with knowledge of the equipment and batteries the charger will be used with should install the charger.
