Multipoint Earthing Control System | StuvEx MGS01

Safe Earthing of Vessels & Drums for Hazardous Areas & Explosion Protection

The MGS01-V1 earthing control system is ATEX Certified to provide static earthing control and dissipation of accumulated static electricity in hazardous area industries with potentially explosive atmospheres, this includes Zone 1 (21) and Zone 2 (22) flammable gas and combustible dust applications.

The Multipoint Earthing Control System is suitable for simultaneous earthing of one to up to 10 conductive objects. When loading or unloading flammable, conductive liquids or powders, electrostatic charges can be generated. If the electrostatic energy generated is sufficiently large, a discharge spark may cause a fire or explosion. This risk is avoided by connecting all conductive parts to earth.

The earthing system which is manufactured by StuvEx and distributed by Thorne & Derrick, forms part of a preventive operating system in a process plant for use in hazardous areas with potentially explosive atmospheres.

➡ Thorne & Derrick together with StuvEx supply Static Bonding Clamps, Cables & Connectors to the hazardous area EX industries with over 35 years experience.

The Multipoint Earthing Control System MGS01 forms part of the range of static earthing products and systems – the Earthing Control System consists of a power box, one up to 10 resistance control boxes, one up to 10 loose cable(s) or coiled cable(s), one up to 10 earthing clamps, supplied with or without connector set.

MGS01-V1 Earthing Control System Operation

The MGS01 earthing system consists of an MGS01-V1-PB (Power Box) and one or more MGS01-V1-RCB (Resistance Control Box). The earthing system is designed to ground conductive objects in a safe and controlled way using an earthing clamp to ensure safe loading or unloading operations. The earthing system forms part of a preventive system in process installation.

Earthing Control Unit MGS01-V1

The MSG01-V1 earthing system consist of:

One Power Box, type MGS01-PB
One up to 10 Resistance Control Boxes, type MGS01-RCB One up to 10 loose cable(s) or coiled cable(s), type SPxx-HD
One up to max. 10 earth clamp(s), type CSS1 or CMS1, supplied with or without connector set

Cable or Spiral Cable

You can choose between flat cable (10 m), spiral cable (3 m – 5 m – 10 m) to connect the MGS01-V1 to the objects to be earthed.

Active Earthing Clamp

With active clamps, the two clamping jaws are isolated from each other as well as isolated from the clamping body itself. As long as the clamps are not connected to a conductive object, the circuit between the clamping jaws remain open and no current can flow. Once the clamp is attached to the earthing point of the truck, the circuit is closed.

How The Multipoint Earthing Control System Works?

The MGS01 earthing system, when connecting the earthing clamp, will discharge the electrostatic charge present on the object to earth in a safe and controlled manner. After discharging, the object is connected to earth by the MGS01 earthing system with a low-impedance connection As long as the device has this low resistance (< 10 Ohms), the release contact is switched and a green LED will illuminate.

During unloading or charging, the connection is permanently monitored. If the connection is broken, a red LED will light. Via an interlock contact, the MGS01 earthing system can be connected to the process plant and automatically interrupt unloading or loading. Restarting the cycle is done by disconnecting and reconnecting the earthing clamp.
