6.4
Temperature sensor/anti-condensation heating connection
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 that are 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,
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.
6.4.2
Auxiliary circuit connection
Auxiliary circuits are connected in the terminal box.
6.5
Conductor connection
Cross-sections that can be connected depending on the size of the terminal (possibly reduced
due to size of cable entries)
1MB..5/6 shaft height 71 ... 355
