The TUE30 Terra-Control ground monitoring system is designed for use when filling or discharging potentially explosive materials. The system effectively eliminates any static charges. The proper ground connection of installations reduces the risk of uncontrolled explosions or fires. The TUE30 system monitors the connection to the bonding conductor and the contact across the ground clamps. This function controls a potential-free changeover contact, which allows to controle optical or acoustic primary detectors, locking mechanisms, pumps, slide valves etc. The modular system of the Terra-Control TUE30 is available in the following design versions: • TERRACOMPACT II TCO030, standard enclosure for mounting on a standard rail NS35 for installation in a control panel or control room • TERRABOX TCB030, wall-mounted enclosure for direct installation in the hazardous zone. Technical Information Ground monitoring system Terra-Control TUE30 TI-en-4003-2002 TERRACOMPACT II and TERRABOX are each designed for connecting one ground clamp or a cable rewinder fitted with ground clamp. For BIG BAG grounding, two ground clamps can be connected to the TERRABOX and to the TERRACOMPACT II.
