USER’S MANUAL FOR OPERATION
You can not connect the GNOM and other devices (accessories) to the mains
with the following problems:
•
Wrong/incorrect wire connections of the L and N conductors in the
appropriate slot.
•
Without protective earthing conductor.
•
Without voltage transformer.
Note. Before use, the operator should always check the correct wiring
connections (phase conductor - L), e.g. by phase tester.
Checking the RCBO
Checking the RCBO (residual-current circuit breaker with overcurrent protection)
must be performed before any underwater operation at the new location.
• If the requirements of paragraph
2.2.1
are met, connect only the surface
module to the power supply.
• Switch the main switch 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 main switch on the control panel off. Switch the RCBO on.
• Switch the power main switch on the control panel on again. RCBO must
remain switched on.
