Notes on configuration The control of loads parallel to the start input is not permissible in AC opera-
tion. See the relevant circuit diagram ¿ below.
The off-delay solid-state time relay blocks (3RT1916-2D.../3RT1926-2D...)
have a live start input (B1). With AC voltage, this can imitate the control of a
parallel load on the B1 terminal. In this case, an additional load (contactor
K3, for example) should be wired as shown in circuit diagram À.

3.4.3.1 Frame size S00 (3RT1916-2C, -2D)
Caution
Switch off the supply voltage to A1/A2 before you install or remove the
solid-state time relay block.
Installation/removal Important
The time-delay auxiliary switch cannot be attached to contactor relays.
The solid-state time relay block of frame size S00 is attached to the front of
the contactor and latched into place with a pushing movement.
