Precautions

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH

• Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462, or NOM-029-STPS.
• This equipment must be installed and serviced only 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.

WARNING: This product can expose you to chemicals including DINP, which is known to the State of California to cause cancer, and DIDP which is known to the State of California to cause birth defects or other reproductive harm. For more information go to: www.P65Warnings.ca.gov.
The product has been designed for environment A (Class A, IEC 60947-1). Use of this product in environment B (Class B, IEC 60947-1) may cause unwanted electromagnetic disturbances in which case the user may be required to take adequate mitigation measures.

Installation

1. Turn off all power supplying this equipment before working on or inside equipment.
2. Trip the circuit breaker (Figure 1, a–c).
3. Use a properly rated voltage sensing device to confirm power is off.
4. Remove the handle extension (d). FIG. 1 :
   Visi-Trip™
   The Visi-Trip LED handle aids in quickly locating a circuit breaker that requires attention. Inspect the handle position for circuit breaker trip indication. The VisiTrip handle will flash an LED light as described in Table

5. NOTE: When performing annual maintenance in accordance with MCCB Field Testing and Maintenance Guide (0600IB1201), operate the push to trip button (if equipped) to verify the Visi-Trip functionality. Cycle the circuit breaker from tripped to OFF, and then from OFF to ON and take not of the battery health. See Table 2.
   Wait five seconds between handle operation and push-totrip button operation to ensure that the Visi-Trip handle is on standby mode. Tripping the circuit breaker too soon after toggling may result in the VisiTrip handle not operating as intended.

handle position for circuit breaker trip indication.

1. Refer to the Schneider Electric Frequently Asked Questions page. https://www.se.com/us/en/faqs/home/for more information.
2. If a nuisance LED flashing occurs on ON or OFF position, it can be reset by toggling the circuit breaker. If toggling the circuti breaker is not desired, LED flashing will reset after six hours.
