Dry Contact Relay
To use your dry contact output fail relay you must connect a 9-pin D connector to the
unit. You must use pins one and six as is indicated on page 7 in the remote connector
diagram.
The relay is factory preset to fail in the closed position when the low output LED
and buzzer come on. If you wish to have the relay fail in the open position when
the low output LED and buzzer come on, you must take the cover off the unit and
move the jumper to the other position on J11. J11 is located next to the relay.
To change the position of the jumper, first turn the unit off and disconnect the unit from
both the input and output power. Next, turn the unit on for 30 seconds to discharge the
capacitors, then turn it off again. Turn the unit upside down and remove the four screws.
Remove the cover and locate J11. It will be next to the relay as is shown in the above
diagram. Simply move the jumper to the desired position as is shown in the above dia-
gram. Replace the cover and re-install the four screws. Reconnect the unit to the input
and output power.

IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
— This manual contains important safety and operating
instructions for the converter.
ALL CONVERTERS
1) CAUTION — To reduce risk of injury, charge only lead acid or sealed gel cell
type rechargeable batteries. Other types of batteries may burst causing per-
sonal injury and damage.
2) Do not expose converter to rain or snow.
3) Use of an attachment not recommended or sold by the converter manufac-
turer may result in a risk of fire, electric shock, or injury to persons.
4) Do not disassemble converter; take it to a qualified serviceman when service
or repair is required. Incorrect reassembly may result in a risk of electric shock
or fire.
5) To reduce risk of electric shock, disconnect converter from batteries or other
DC supply before attempting any maintenance or cleaning. Turning off controls
will not reduce this risk.
6) CONVERTER LOCATION
i) Never place converter directly above battery; gases from battery will
corrode and damage converter.
ii) Never allow battery acid to drip on converter when reading gravity or
filling battery.
7) DC CONNECTION PRECAUTIONS
i) Connect and disconnect DC output connections only after setting
converter switch to off position.
