TeSys T Retrofit Applications

DANGER
Hazard of Electric Shock, Explosion, or Arc Flash Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS-2011, or CSA Z462. This equipment must only be installed and serviced by qualified electrical personnel. Turn off all power supplying this equipment before working on or inside equipment. Always use a properly rated voltage sensing device to confirm power is off. Replace all devices, doors, and covers before turning on power to this equipment. Failure to follow these instructions will result in death or serious injury.

NOTE: For retrofit applications, contact your local Schneider Electric representative for assistance. Schneider Electric assumes no responsibility for the design or implementation of retrofits unless contracted to perform them. See Schneider Electric data bulletin no. 8998DB1004 for upgrade of the Motor Logic™ Plus or Motor Logic Plus II solid state overload relay to the TeSys™ T motor management system.

Remove the starter from the unit to replace the overload (melting

alloy/bi-metallic). See Removing the Control Unit.

Terminal blocks (OEKTTBML) should be used for two-speed applications requiring multiple passes to achieve the proper adjustment range.

Restrain looped load cabling between the TeSys T controller and the terminal block with wire ties (or the equivalent) when terminal kits are used.

On 600 V Size 1 applications, add a third wire tie between the circuit breaker and contactor near the contactor line lugs. Refer to instruction bulletin 30072-013-29 for additional information.

Use copper wire only on device power and control terminals. Conductors must be sized for 60 °C or 75 °C National Electrical Code^® (NEC^®) ratings.

Pressure wire terminals are suitable for single conductor wire sizes #24–14, solid or stranded. Two conductor wire size is #24–18. Terminal instruction labels are located adjacent to the terminal block or on the wireway door.
