Power Stack Electrical Installation

Please read the Safety Information in 'Chapter 1: Safety' before proceeding.

WIRING INSTRUCTIONS

Protective Earth (PE) Connections
The unit must be permanently earthed.
Refer to 'Appendix A: Compliance' for further information.
Supply Fuses / Circuit Breakers
Protect the incoming mains supply using suitable fuses or a circuit breaker (circuit breaker types RCD, ELCB, GFCI are not recommended).
Refer to 'Chapter 6: Associated Equipment – Power Stack' for recommended fuses, and other systems components that may be required for use
with the inverter.
DANGER – RISK OF ELECTRIC SHOCK
Terminal covers, main covers, and cover fixings must remain in place while the drive is energised.
These should only be ever be removed once the supply to the unit has been disconnected, and the residual energy in the DC link
capacitors has been discharged.
All activities covered in this chapter should be carried out when there is no power to the inverter.
If the drive has been powered up, ensure enough time has elapsed that the inverter has discharged it's residual energy.
Always check that the voltages on the user terminals are at a safe level (<50V) before carrying out any of these activities.
STO always overrides any attempt to start the inverter. If one or both STO control inputs is requesting the STO function, the inverter
will not start, even if for example, the inverter's software malfunctions and tries to cause the motor to turn.
Refer to 'Chapter 8: Safe Torque Off SIL3/PLe' for further information.
