2 BASIC INFORMATION & QUICK REFERENCE
2.1 Product overview
DigiTRON connectors intended use is to provide low voltage and communications links between
pieces of electrical equipment that are submerged in water, e.g. subsea.
The DigiTRON range of connectors have been developed for longterm reliable communications and
low voltage power control system applications associated with offshore installations. The underwater
mateable capacity of these connectors is achieved using pressure compensated electrical inserts
employing the CE principle.
Examples of connectors are shown in section 2.7.
Table 2 identifies each product type in the DigiTRON product range.

Caution. Risk of material damage. Maximum cumulative exposure of the male pins to
seawater is 28 days to prevent corrosion of the pins. If the connectors are to be left
unmated, in seawater, for any length of time Subsea Environment Cap or Dummy Plug
must be fitted to protect the pin contacts in the receptacle connectors. Over exposure will
increase the risk of corrosion damage or marine growth on the contact surfaces of the
receptacle contact pins. This could lead to damage to the seals and insulation within the
plug socket contacts. Plug connectors do not require full dummy connectors for
protection. Siemens Energy Subsea advise the fitting of acetal caps to protect plugs
against marine growth. It is good practice to always fit the protective cap when a
connector is unmated topside prior to deployment to provide mechanical protection.
Caution. Risk of material damage. Unmated receptacles (exposed male pins) should
never be electrically energised subsea (even a small residual voltage). This will very
quickly corrode the pins or cause complete electrical failure of the product.

6 PREPARING PRODUCT FOR USE OR STORAGE
6.1 Product protection and packaging
Siemens Energy Subsea electrical connectors are manufactured primarily from materials such as
316L stainless steel and Super Duplex stainless steel, and as such are designed to withstand harsh
saliferous environments. However, the connector inserts and exposed parts are susceptible to
mechanical damage if not protected. Transport caps or Acetal protective caps must be fitted to all
Siemens Energy Subsea connectors before transport.
Caution. Risk of material damage. Transport caps or protection caps must always be fitted
to an unmated connector during transport, and should remain in place while topside before
deployment
Connectors can be shipped singularly or in multiples. Care should be taken to protect the
connector(s) with ‘Instapack’, bubble wrap or similar wrapping materials to avoid surface damage
during transit. If large numbers are shipped in one consignment suitably reinforced transport box will
be necessary to withstand the weight. See Figure 7 and Figure 8.
Figure 7 Acceptable packaging for shipment
Figure 8 Unacceptable packaging and storage
Bulkhead type connectors with exposed tailing wires should be packed and shipped in a suitably
sized box to allow adequate space for the tailing wires without bending or kinking.
Connectors are designed to withstand vibration that occurs during transportation and to withstand
being dropped from a height of 1m (3.3 ft) whilst in packaging.
If the connectors are assembled onto hoses these must be suitably coiled and secured with tape to
prevent uncoiling during transit. Respect the hose minimum bend radius (125mm (4.9”) for
AquaTRON 50, 180mm (7.1”) for AquaTRON 75).
