*Installation: Peel the ThermoSpot-BTM label from the backing paper. Apply to a dust & grease free surface. Apply onto external surfaces of busbar. Ensure that the labels are applied to a surface that will be visible when in use. Endeavour to not touch, scratch or damage the surface of the label. The Indicator spot will change color from pink to red if the surface temperature reaches 52˚C setpoint. If a label turns Red (alert temperature) switch off appliance and seek advice from a competent electrician. For indoor use only.
*Caution: These labels are designed for use only on external surfaces of busbars and general electrical equipment.
LIMITATIONS: • These labels are not suitable for unprotected use outdoors or in direct sunlight. They are vulnerable to degradation and non-performance from prolonged exposure to ultra-violet (UV) light or high Relative Humidity. • These labels will not prevent electrical faults or fires but will aid in monitoring abnormal temperatures and will give visual indication of potential electrical faults and fire risks. • These labels do not replace the need to formally install, test, inspect and maintain electrical installations as per the Electricity at Work Act, the Electrical Installation Wiring Regulations and Manufacturer’s Instructions. • This information is provided solely for consideration, investigation and verification by the user. ThermoSpot-B are made to the highest standard however they are not suitable for all environmental applications. The customer must ensure that they are suitable for use in their application.
