2. USER’S MANUAL FOR OPERATION
2.4.1
NOTE
You cannot connect the GNOM and other devices (accessories) to the mains with the
following problems:
• incorrect wire connections of L and N conductors in the appropriate slot.
• without protective earthing conductor.
Note. Checking the correct wiring connections (phase conductor - L) inspects the
operator. (E.g. by phase tester)
2.4.2 Checking the RCBO
Checking the RCBO (residual circuit breaker with overcurrent protection) must be
performed before any underwater operation at the new location:
• If the requirements of paragraph 2.4.1 are met, connect only the surface module to the
power supply.
• Switch the mains voltage button on the control panel on.
• After 5 seconds, press the "TEST" button on the RCBO. It would immediately lead to a
safe shutdown of the module.
• Switch the mains voltage button on the control panel off. Switch the RCBO on.
• Switch the power supply button on the control panel on again. The RCBO must remain
switched on.
