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 are provided with Solid-State Short-Circuit (output) Protection. Integral solid state short
circuit protection does not provide branch circuit protection. Branch circuit protection requirements must be
in accordance with the latest edition of the National Electrical Code NEC/NFPA-70 and any additional
local codes.
Refer to the 890 Installation Kit for earth/ground fixing details. Fit the appropriate parts.
Each unit must be
permanently earthed
according to EN 50178.
For permanent earthing:
A cross-section conductor of at least 10mm² is required. This can be achieved either by using a
single conductor (PE) or by laying a second conductor though separate terminals (PE2 where
provided) and electrically in parallel.
