People Authorized to Install the ProbeSensor

DANGER

hazard of electric shock, explosion, or arc flash The installation, removal, and commissioning of the probesensor must be carried out only by skilled, professional and qualified electrical personnel. In addition to site requirements, all work is carried out in accordance with the current revision of Schneider Electric Electrical and Mechanical Safety Rules. The following parts related to Safety must be considered and applied by Schneider Electric employees. Failure to follow these instructions will result in death or serious injury.

Safety Checklist

• Is the transformer de-energized and lines grounded (LockOut TagOut procedure followed)?

• Is the transformer temperature less than 40 °C (104 °F)? Record the temperature by reading the transformer oil temperature indicator or by using a laser thermometer.

• The EcoStruxure™ Transformer Expert ProbeEcoStruxure™ Transformer Expert Sensor H2 (hereafter referred to as ETE ProbeETE Sensor) may be installed on the top oil valve or the External Temperature Sensor installed around the top pipe to the radiator. Are these parts safely accessible from ground-level?

• Is appropriate personal protective equipment (PPE) available and used?

Transformer Operator’s Responsibility

DANGER

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Wear appropriate personal protective equipment (PPE) and follow safe electric work practices. See NFPA 70E or CSA Z462. Make sure that the equipment is only installed and serviced by qualified electrical personnel. Only mount or unmount the probesensor when the transformer is de-energized. Turn off all power supplies to equipment and the transformer before working on or inside it. Respect the LOTO (Lock Out Tag Out) procedure. Always use a properly rated voltage sensing device to confirm that power is off. Before turning on the switch, check that all devices, covers, and doors are in the correct position. In addition, check that the downstream circuit is not earthed and ready to be energized. Before operating the switch, check that interlocks and protective barriers are not removed. Never go near the equipment when the transformer is energized. The transformer operator is responsible for checking that the following points are adhered to. Failure to follow these instructions will result in death or serious injury.

CAUTION
HAZARD OF hot surface Wear appropriate personal protective equipment (PPE) to protect from hot temperature. Do not touch the cooling system nor the tank cover without thermal protection. Failure to follow these instructions can result in injury or equipment damage.

• Select appropriate probesensor to help ensure the proper functioning of the system or machine. Schneider Electric can only make recommendations based on our experience with similar applications.

• Follow all safety instructions in this manual and additionally apply all local regulations.

• Advise the installation team of installation risks and provide suitable control measures to help ensure the safety of staff.

• Identify hazardous processes in the vicinity of the workplace and provide suitable control measures to help ensure the protection of installation staff.

• Provide site-specific training before commencement of work, including site access and egress.

• Provide emergency procedures and associated emergency telephone numbers (if applicable).

• Check the legibility of the type plate.

Cleaning Instructions

The ETE ProbeETE Sensor is IP65-rated and requires cleaning once a year. Cleaning frequency increases in harsh environmental conditions (extreme cold or heat). During scheduled transformer maintenance, the probesensor may be cleaned to remove any accumulation of dust, oil, snow, or any other pollutants.
