RELAYCARD-SDU

Suitable electric wire for the terminal blocks is 22–12 AWG (IEC 2.5 mm), ensuring proper and safe electrical connections.

The terminal blocks have a maximum contact current rating of 1.0 A at 250 V ac, which is important for safe operation.

An external remote device can provide a shut down input signal by enabling terminals 7 and 8. The signal range is +5 V to +12 V.

The shut down input signal range for remote control is +5 V to +12 V, provided by enabling terminals 7 and 8.

The kit includes one dry contact relay box, an interface cable (DB-9), a 12 V dc power interconnection cable, and four M3 mounting screws.

Only qualified personnel should install or service this system. Always turn off and lock out all power sources to the unit before making electrical connections to prevent shock.

It is powered by a 12 V dc input. Plug the provided power interconnection cable into the relay box's Vin port and the SDU UPS's aux dc output.

Plug the DB-9 connector cable into the RS232 communication port of the SDU UPS and the remote port of the dry contact relay.

The red Shut Down LED illuminates when the dry contact relay receives a shut down signal for one second, initiating shut down mode for the SDU UPS.

Push the Shut Down Test button for one second while the UPS is in battery mode. The red LED will illuminate, and the SDU UPS will shut down after three minutes.
