Relay Connection

Three  SPDT  relays  are  provided  on  the  power  supply  board.    None  of  the  relay  contacts  are
powered.  The user must supply the proper power to the contacts. For applications that require the
same  switched  operating  voltage  as  the  Q46  (115  or  230  V),  power  may  be  jumpered  from  the
power input terminals at

TB7.

Relay wiring is connected at

TB4, TB5, and TB6

as shown below.

Note that the relay contact markings are shown in the NORMAL mode. Programming a relay for
“Failsafe” operation reverses the NO and NC positions as shown in diagram below.
