Marine Grounding System

Effective potential equalization between ship and shore prevents possible formation of sparks and hot spots
Highest safety by interruption of the battery effect (galvanic cell) between ship and shore
Automatic shut off of product flow, when grounding is interrupted
Explosion protection for worldwide use according to IECEx and the European ATEX directive 2014/34/EU (zone 1) – IECEx approval not yet finalized –
As absolutely essential safety component even when insulating flanges are used

Various control outputs, e.g. for connection to an additional status indicator to display an unsafe status
Marine Grounding Clamp with 2 integrated status LEDs
Effective failure diagnosis by integrated system information display (incl. 10 status-LEDs)
Object recognition of the ship
The electrical conductive bonding line connection between ship and shore is released, after a proper mechanical and electrical contracting is monitored
Detection of incorrectly connected clamp or pull off and immediately switching into safe status

Benefits

Very low-ohmic measure line, especially for maritime application

Opening of the housing during operation in hazardous areas is allowed

2 clearly visibly LEDs at the device front

Easy check of a proper grounding connection due to status LEDs at the grounding clamp

Usage under extreme environmental conditions (sturdy stainless steel housing with IP 65) and wide temperature range (-40 °C to +60 °C)

Over 30 years of experience with Marine Grounding Systems
