PRODUCT OPERATION AND MAINTENANCE
9.1
Safety precautions
Before use, read section 3 on product safety advice.
9.2
Product maintenance and servicing
DigiTRON products require zero maintenance for their 30 year subsea lifetime and up to 250 subsea
mate and de-mate cycles.
There are no user serviceable parts in the connectors. Disassembly of the product should not be
attempted. If there are any problems developed with the product then the user should contact
Siemens Energy Technical Support for advice
9.3
Subsea protection of receptacle contact pins
Caution. Risk of material damage, corrosion of the exposed male pin in the receptacle
connector.
28 days is the maximum cumulative allowable exposure of unprotected receptacle pins to
seawater over the lifetime of the connector
Always immediately fit a Subsea Environment Cap or Dummy Plug to the
receptacle in order to protect the pins from corrosion.
Caution. Risk of material damage. Under no circumstances must the contact pins in the
receptacle connector be exposed to seawater with power on.
If this situation does occur the electrical connector could be destroyed (depending on
electrical energy available). At a minimum, the contact surfaces of the pins will very rapidly
degrade by electrolytic action. If these damaged pins are subsequently mated into a socket
insert there is a very high risk of damage to the insulation and seals within the plug
connector.
Caution. Risk of material damage. It is important to isolate and earth prior to disconnect
in order to remove any stray charges in the system. If left, this can induce corrosion on the
exposed pins once the plug is removed.
