Installation, commissioning and maintenance
The following set values apply for the measuring circuits:
•
Voltage monitoring
•
IMD
- Insulation monitoring
- Temperature monitoring
- Load monitoring of IT transformer
The response value of the load current can be set
7LQ3 361 Terminal –X2: 12 (l) and 13 (k)
7LQ3 362 Terminal –X2: 14 (l) and 15 (k)
These terminals are only for the setting of the load current response value.
It is not allowed to use these terminals for any other case. Maximum current is
10 A, because of the conversion rate 1:5.
The terminals for setting the load stay unlinked and shall not be bridged.
