13. Electrical Connection
Caution, risk of death
Unconnected and / or faulty protective conductor systems can lead to dangerous voltages and electric shocks
which can cause serious accidents.
Work on electrical connections may only be carried out by trained electrical engineers.
Door Switch
The unit can be switched ON and OFF 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, 10(10)A @ 250Vac
100000 cycles
UL 873
8A 2FLA 12LRA, 12A 12FLA 72LRA @ 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
Short Circuit Current Rating (SCCR)
on methods
how to modify the available short circuit current within a circuit in the panel.
