Dear customer, The controlled grounding principle used in the TERRALIGHT Ground Monitoring System ensures that static charges developing in potentially explosive atmospheres, e.g. during loading, discharging or refilling are safely avoided. This means that the risk of ignition caused by uncontrolled static discharges is eliminated at source. Because the ground connection is monitored, there is no need for low-resistance ground connections or large conductor cross-sectionsStatic charges are caused by the contact and separation of material surfaces, e.g. when pumping liquid or powdery materials...

2. Safety The units have been designed, built and tested using state-of-the-art engineering, and have left the factory in a technically and operationally safe condition. If used improperly, the units may nevertheless be hazardous to personnel and may cause injury or damage. Read the operating instructions carefully and observe the safety instructions. 2.1 Identification of risks and hazards Possible risks and hazards resulting from the use of the units are referred to in these operating instructions by the following symbols: Warning! This symbol appearing in the operating instructions refers...

2.4 Work and operational safety Warning!electricians Carefully observe the following notes and the complete Chapter 2 "Safety”, page 7! • The local standards, rules and regulations relating to the installation and operation of electrical appliances in potentially explosive atmospheres must be observed (e.g. EN 60079-14 and EN 60079-17 in the EU and ElexV in Germany). • Appliances designed for use in potentially explosive atmospheres must not be modified. The technical specifications for ambient conditions and operation must be maintained and observed (see Chapter 8 "Technical specifications”,...

• The maximum cable length in the intrinsically safe circuit must not exceed the maximum permissible capacity and inductance (see Chapter 8 "Technical specifications”, page 27). • The ground monitoring system must always be connected to the equipotential bonding conductor (see Chapter 3.4.1 "Cable connection”, page 15). • If the ground cable is subjected to tensile stress in the application (e.g. if KG/BN_ (ground cable) or KG/BS_(helix ground cable) is used), the cable must be secured additionally with an external strain relief (e.g. a strap clip); see Chapter 3.4.1 "Cable connection”, page...

2.5 Special conditions according to the declaration of conformity • Only the following battery types (D cells) may be used to operate the TERRALIGHT system: - Duracell Plus Power MN 1300 - ENERGIZER MAX LR20 - ENERGIZER LR20 ALKALINE POWER (see Chapter 3.4.2 "Changing batteries (Fig. 6)”, page 16). • The batteries may only be replaced if it can be ensured that a potentially explosive atmosphere does not exist at this instant of time (see Chapter 3.4.2 "Changing batteries (Fig. 6)”, page 16). • Equipotential bonding (PA) shall be established along the entire cable run of the measuring circuit...

3. Assembly and installation Attention! Once the TERRALIGHT ground monitoring system has been assembled and installed, it must be tested for proper functioning, see chapter 4.3. 3.1 View of appliance TERRALIGHT Connection of the ground contactor / cable rewinder Battery case Connection PAL Adapter with cable gland Signal light (surrounding) Locking screw against unintentional opening of the battery compartment Ground connection

When installing the system in explosion hazard areas, every precaution must be taken to ensure that a potentially explosive atmosphere does not exist at this instant of time! The TERRALIGHT ground monitoring device is approved for assembly and installation in potentially explosive atmospheres. The system is designed for wall mounting and is attached with the mounting brackets. The point of installation must be dry and the indicator lamp must remain in full view. Avoid direct exposure to sunlight. Fig. 4: Mounting Dimensions TERRALIGHT * Space for battery change
