• Seal with moisture-proof materials to prevent corrosion.

3.2 Handling

• Use forklifts, cranes, or hoists with proper lifting points.

• Avoid tilting, dropping, or excessive force.

• Transport in upright position as specified in manufacturer manual.

3.3 Storage Before Installation

• Store in dry, ventilated area.

• Maintain ambient temperature between -10°C and +40°C.

• Avoid direct sunlight, rain, or dust accumulation.

4. Installation Conditions and Guidelines

4.1 Site Selection

• Ensure stable, level foundation for proper alignment.

• Maintain minimum clearance around equipment for operation and maintenance.

• Avoid areas with high vibration, corrosive gases, or flooding risks.

4.2 Environmental Requirements

4.3 Power Supply Considerations

• Ensure appropriate medium voltage line connection.

• Verify earthing/grounding systems according to IEC standards.

• Confirm protection devices (fuses, relays) are installed as recommended.

5. Quick Installation Guide

5.1 Tools and Equipment Needed

• Torque wrench and insulated tools

• Lifting equipment (crane/forklift)

• Level and measuring tape

• Personal Protective Equipment (PPE)

5.2 Installation Steps

1. Position the Recloser: Place on prepared foundation.

2. Secure with Anchor Bolts: Ensure cabinet is level and stable.

3. Connect Incoming and Outgoing Lines: Follow wiring diagram precisely.

4. Grounding Connection: Connect to earthing system according to standards.

5. Mechanical Operation Test: Verify smooth movement of switch and interlocks.

5.3 Installation Checklist

6. Operational Principles

The ZW32 recloser operates on automatic detection and reclosing principles:

1. Fault Detection: Current sensors identify short-circuit or overload conditions.

2. Trip Action: vacuum circuit breaker interrupts the fault current instantly.

3. Reclosing Action: Automatic reclosing restores power if the fault is temporary.

4. Lockout Mechanism: Prevents reclosing on persistent faults.

5. Manual Override: Allows operators to intervene if required.

7. Maintenance and Inspection

Routine maintenance ensures reliable operation and long service life:

7.1 Routine Maintenance Tasks

7.2 Preventive Measures

• Avoid exposure to moisture and dust.

• Tighten electrical connections regularly.

• Verify interlocks and safety devices are operational.
