7.6 Mounting
7.6.1 Mounting instructions
Solid-state timing relays with semiconductor output/solid-state time-delay auxiliary switches
Note
For the "OFF-delay without auxiliary voltage" function
The setting of the output contact is not defined in as-supplied state (bistable relay). Connect
the control voltage and then disconnect it again to set the contact to the normal position.
Note
The solid-state time-delay auxiliary switch cannot be attached to coupling relays.
7.6.2 Minimum clearances and mounting position
Minimum clearances and mounting position
The minimum clearances and the mounting position are set dependent upon the type of
mounting.
See Mounting position in the chapter titled Contacto
rs/Contactor assemblies (Page 148).
7.6.3 Mounting
7.6.3.1 Function modules for direct-on-line start (solid-state timing relay with semiconductor
output/solid-state time-delay auxiliary switch)
DANGER
Hazardous Voltage
Will Cause Death, Serious Injury or Property Damage
Turn off and lock out all power supplying this device before working on this device.
The function modules for direct-on-line start (solid-state timing relay with semiconductor
output/solid-state time-delay auxiliary switch) are connected to the front of the contactors.
