6.4
Connecting a temperature sensor / anti-condensation heating
WARNING
Hazard due to electric shock
The installation of the temperature sensors for the winding monitoring with respect to the
winding is implemented according to the requirements for basic insulation. The temperature
sensor connections are located in terminal boxes, safe to touch, and have no protective
separation. This is the reason that in the case of a fault, a hazardous voltage can be
present at the measuring sensor cable. When touched, this can result in death, severe
bodily injury and material damage.
•
When connecting the temperature sensor to external temperature monitoring devices,
when required, apply additional measures to fully comply with the requirements set out
in IEC 60664-1 or IEC 61800-5-1 "Hazard due to electric shock".
6.4.1
Connecting optional integrated devices and equipment
In addition to the current-dependent overload protective device located in the connecting
cables, use the optionally available integrated devices and equipment, for example,
temperature sensors, anti-condensation heating.
