⚠️ Electrical Safety and Usage Disclaimer ⚠️

All electrical products supplied by WCTNZ® — including 240 V AC systems and Extra Low Voltage (ELV) systems (≤50 VAC / ≤120 VDC, e.g. 12–48 VDC) — must be installed, connected, and operated in accordance with New Zealand electrical safety standards (including AS/NZS 3000 and AS/NZS 3820).

WCTNZ® does not design, certify, or install power systems, and accepts no liability for damage, malfunction, injury, fire, or loss resulting from:

• Installation or servicing by unqualified persons
• Use with incompatible or unstable power sources (e.g. non–pure sine wave inverters, low-quality DC supplies, or incorrect voltage/frequency)
• Modifications to wiring, terminals, or internal components
• Failure to implement adequate electrical protection (e.g. RCDs, MCBs, fuses)
• Lack of proper earthing (AC) or isolation/protection (ELV)
• Use outside the product’s rated electrical specifications

Off-Grid and ELV Use

• AC products must be powered by pure sine wave inverters with <5% Total Harmonic Distortion (THD).
• Non-compliant inverters may cause overheating, electrical noise, inefficiency, or early failure — not covered under warranty.
• ELV systems (e.g. 12–48 VDC) require stable DC power and properly rated fuses or DC-rated circuit breakers. Even low voltages can pose a significant fire risk if improperly fused or installed.

Installation Requirements

• AC installations (on- or off-grid) must be carried out or verified by a licensed electrician, including testing of earthing and harmonic compatibility
• ELV systems should be installed by a qualified technician or electrician, in accordance with local regulations and good practice

Purchaser Responsibility

It is the customer’s responsibility to ensure:

• The power supply is electrically compatible with the product
• The system is installed and maintained in compliance with applicable NZ standards
• Electrical faults arising from an unsuitable or unstable power supply are not covered under warranty
