Leakage detection connection
DANGER
Risk of explosion due to incorrect connection!
If the connected pump is installed in an explosive atmosphere, there is a risk of explosion due to incorrect connection:
- Switch on ex-mode (menu 5.64)!
- Observe the section on explosive atmospheres in the appendix.
- Connection must be carried out by a qualified electrician.
CAUTION
Do not apply external voltage!
An external voltage which is applied destroys the component.
Leakage detection that uses a moisture probe can be connected for each pump. The threshold (< 30 kOhm) for a deactivation is permanently stored in the switchgear. Do not connect a float switch!
Insert the connection cables laid by the customer through the threaded cable glands and secure. Connect the wires to the terminal strip according to the connection diagram. Use the terminal number shown in the connection overview on the cover. The number shown in location “x” on the symbol indicates which pump it refers to:
- 1 = pump 1
- 2 = pump 2
- 3 = pump 3
