Altistart 22 - Schneider Electric

WiringInstallation PrecautionsDANGERHAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH• Read and understand this manual before installing or operating the Altistart 22. Installation, adjustment, repair, and maintenancemust be performed by qualified personnel.• The user is responsible for compliance with all international and national electrical code requirements with respect to grounding ofall equipment.• Many parts of this soft starter, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH. Use only electricallyinsulated tools.• DO NOT touch unshielded components or terminal strip screw connections with voltage present.• Before servicing the soft starter:- Disconnect all power, including external control power that may be present.- Place a “DO NOT TURN ON” label on all power disconnects.- Lock all power disconnects in the open position.• Install and close all covers before applying power or starting and stopping the soft starter.Failure to follow these instructions will result in death or serious injury.Good wiring practice requires the separation of control circuit wiring from all power (line and load) wiring. Power wiring to the motor musthave the maximum possible separation from all other power wiring. Do not run them in the same conduit. This separation reduces thepossibility of coupling electrical noise between circuits.Follow these precautions when installing the ATS22 soft starter:• Voltage and frequency specifications for the input line must match the soft starter configuration.• A disconnect switch must be installed between the input line and the soft starter.DANGERHAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH• The solid state switches of the ATS22 soft starter’s power circuit do not provide complete isolation from the AC line. Due to leakagecurrents through the solid-state switches, hazardous voltages can be present on the soft starter load-side power circuit wheneverpower is applied to the line side of the soft starter.• Disconnect all power before servicing the soft starter or motor.Failure to follow these instructions will result in death or serious injury.• When using an isolation contactor, the contactor must close before or at the same time as the application of the soft starter runcommand. If line power is not detected at the L1, L2, and L3 terminals of the soft starter within 500 ms of this run command, a PhaseFailure trip will occur.• External overcurrent protection devices (OCPD), either fuses or a circuit breaker, must be installed on the line-side connections ofthe ATS22 soft starter. The maximum recommended OCPD rating, along with the associated soft starter short circuit withstand rating,is listed on the Quickstart S1A14738.26 BBV51330 08/2012
