Specifications are taken from the supplied product information, not independent tests. The 50A figure is specified at 12.6V and should not be assumed at every output setting. Mains frequency, charging-current limits by mode and detailed protection thresholds were not supplied. The two AC ranges do not establish support for voltages between 140V and 160V.

Battery and Equipment Compatibility

Verify battery chemistry, capacity, charging-voltage limits and permitted charging current against the current Stetsom and battery manuals before connection. A stationary-battery mode does not establish compatibility with every stationary battery. Lithium compatibility was not supplied and must not be assumed.

Select the output setting for the connected equipment or approved battery profile. Do not apply the 15.4V setting to equipment or batteries unless their manufacturers explicitly permit it. Charging modes do not guarantee longer battery life or prevent discharge when system demand exceeds the available supply.

Installation and Care

• Have a qualified installer verify polarity, grounding, circuit capacity, fusing, cable size and operating settings.
• Confirm the supply voltage and mains frequency on the actual equipment label before connecting AC power.
• Use an appropriately rated circuit and connectors. DC output current is not the same as AC input current.
• Isolate mains power and follow the manufacturer's battery-disconnection procedure before wiring or servicing.
• Prevent short circuits, keep dry and maintain the required ventilation around the fan.
• Follow battery-manufacturer precautions concerning charging, heat and flammable gases. Do not charge damaged batteries.
• Refer internal servicing to qualified personnel. Built-in protection does not eliminate every installation or operating hazard.
