3.4 Wiring examples
Following Examples 1 - 3 are alternatives on how to start
and stop Emotron TSA via digital inputs.
Example 1 uses separate start and stop signals.
Examples 2-3 shows common start and stop signals.
Examples 4 - 6 shows connections with extended
funtionality.
Start with the connecting the Mains supply, Control supply
and motor cables as follows (common for all examples):
• Connect Protective Earth (PE) to earth bar marked PE
and Motor earth to the earth bar marked see chapter
page 16.
• Connect the softstarter to the 3-phase mains supply (L1,
L2 and L3) and the motor (T1, T2 and T3).
• Connect the control supply voltage (100-240 VAC) to
terminals N and L and the protective earth wire to
terminal PE.
• If required, connect relay R1 (terminals 21 and 22) to
the contactor – the softstarter then controls the mains
contactor (for factory configuration of R1 see menu
[551]).
Always ensure the installation complies with the appropriate
local regulations.
NOTE: Shielded control cables are not mandatory but in
general recommended to avoid disturbances.

NOTE: The TSA is per default using edge controlled
start/stop signals. Remember to change setting of
menu [21A] if you wish to use level signal input.
NOTE: If local regulations state that a mains contactor
must be used, relay R1 should control this see below.
Always use standard commercial, slow blow fuses, e.g.
gl or gG types, to protect the wiring and prevent short
circuiting. To protect the thyristors against short-circuit
currents, ultrafast semiconductor fuses can be used if
preferred. The normal warranty is valid even if ultrafast
semiconductor fuses are not used.
All signal inputs and outputs are galvanically insulated
from the mains supply.
