15. MAINTENANCE
All EFL’S are designed for Subsea immersion and require no maintenance while installed.
15.1 Protection of Receptacle Contact Pins
Under no circumstances must the contact pins in the receptacle connector be exposed to
seawater with power on. If this situation does occur 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.
15.2 Over Current Capacity
Over current capacity for all DigiTRON connectors is 100A for 5 seconds at no more than 2 per
hour.
