Step 2: Connecting Power
In this section we are going to connect the 3-phase supply to the 890SD Standalone Drive(s). We'll also
connect the motor and the (optional) brake resistor.
WARNING
During commissioning, remove the fuses (or trip the circuit breaker) on your 3-phase supply.
Make sure the power is OFF, and that it cannot be switched on accidentally whilst you are working.
Solid-State Short-Circuit Protection
These devices provide Class 10 motor overload protection. The maximum internal overload protection level
(current limit) is 150% for 60 seconds in Constant mode, and 110% for 60s in Quadratic mode. Refer to
Appendix D: Programming - CURRENT LIMIT for user current limit adjustment information.
Motor over temperature sensing is required where the motor has a full-load Ampere rating of less than 50% of
the drive output rating; or when the MOTOR STALLED trip is TRUE (TRIPS STATUS::DISABLED WORD
1>>MOTOR STALLED); or when the STALL TIME parameter is increased above 480 seconds. Motors used
in conjunction with the drive controller shall be provided with PTC sensor(s) or relays suitable for use with
the variable speed drive. Technical details can be found in Chapter 5 890 SD Standalone Drive.
