Question:

2. The temperature rating of the appliance coupler is not based on temperature of the heating
- K/ C- f* E( L' S# Requipment that is able to generate, it is based on temperature of the contacts. Therefore there
is no relation in the way as it is written in IEC61010-1 standard.
Decision:
9 |' o. n/ F. _1. Adequate provision must be provided in the construction of the product and in the

required in particular at the point of entry to the equipment, as well as the parts where it
