Power Supply

Internal Power Supply

The TS trip system is powered by the current through the internal current transformers (CT).

• The standard protection functions of TS trip system operate with the internal current supply.

• If the load current is higher than 0.2 In, the internal current transformers provides the power supply for the full functioning of the TS trip system. This includes:

  • The status bar

  • The ready LED

  • The service LED

  • The trip cause LEDs

  • The protection functions

  • The alarms

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462, NOM-029-STPS or local equivalent. This equipment must only be installed and serviced by qualified electrical personnel. Do not touch live parts during battery replacement. Put back all devices, doors, and covers before turning on power to this equipment. Beware of potential hazards, and carefully inspect the work area for tools and objects that may have been left inside the equipment. Failure to follow these instructions will result in death or serious injury.

When there is no power supply to the TS trip system, the internal battery powers:

• The status bar

• The ready LED

• The trip cause LEDs

The internal battery of the TS trip system can be replaced on site when discharged. The replacement can be made with the circuit breaker in the open or closed position, and the trip system supplied with power. A test of the internal battery must be carried out immediately after the replacement to check the correct functioning of the new battery.

Order a new battery with the Schneider Electric commercial reference M012115.

For information about internal battery replacement and installation, refer to the instruction sheet on the Schneider Electric website: PKR86279.

Battery lifetime is 5 years in the following conditions:

• Ambient temperature at 25°C.

• 2 trips per year, with LEDs supplied by the battery during 2 hours.
