Door Switch
The unit can be switched on and of via a door contact switch. When delivered the door contact terminals are
bridged on the female connector. To connect the door contact switch remove the bridge and connect door
contact switch. The contact must be closed when the cabinet door is closed.

Alarm Contacts
Alarm contacts rated according to:

EN60730-1 8(4)A N.O., 6(4)A N.C., 2(2)A N.O./ N.C. @ 250Vac 100000 cycles
UL 873

8A resistive 2FLA 12LRA, pilot duty C300 @ 250Vac 30000 cycles

These contacts are not suitable for fluorescent loads (neon lights, etc.) that use starters (ballasts) with phase
shifting capacitors. Fluorescent lamps with electronic controllers or without phase shifting capacitors can be
used, depending on the operating limits specified for each type of relay.

SCCR
Refer to UL508A Supplement SB and Seifert Systems’ document
