3) Electrical connections
Wire the starter into the circuit while observing
- the
rated voltage of the main circuits
- the prospective short-circuit current and the required short-circuit protection
- that the auxiliary supply voltage corresponds to the rated control voltages of
the starter components
- the required wire gauge according to the load current, the insulation material,
the ambient temperature, the method of installation and grouping .
4) Settings
- Set the motor protection device to the data of the respective motor:
- Direct starters and reversing starters:
Setting = rated motor current
- Y/ ∆ starters with the motor protection relay in the line connections (circuit-
breaker):
Setting = rated motor current
- Y/ ∆ starters with the motor protection relay in the delta loop:
Setting = 0.58 x rated motor current
- In the case of Y/ ∆ starters, set the timer to the expected starting time (if this
is not precisely known, ensure timer setting exceeds estimated starting time).
The motor should almost reach its rated speed before being switched to delta
operation.
5) Tests
Check that the starter has been installed, wired and is operating correctly while
testing the control system or assembly. The tests should include:
- verification that all screws are tight
- visual inspection of wiring and connections
- insulation test (e.g. by measuring the insulation resistance)
- verification of protective measures, protective earth connections
- functional
check
- verification of the settings of protection devices, timers etc.
Perform any other tests required by the applicable regulations for the control
system or assembly (e.g. IEC/EN 60204, IEC/EN 60439).
