NEMTEK Manuals & User Guides

Since 1990, the NEMTEK Group of Companies has been a globally recognized manufacturer and distributor of intelligent electronic agricultural fencing systems and perimeter security solutions.

Their extensive product line includes high-quality electric fence energizers (such as the WIZORD and Merlin series), keypad controls, lightning inhibitors, and drive-through swing gate systems. NEMTEK holds a strong presence across Africa, Australia, and Europe, continually updating its products to meet stringent international safety and security standards.

• How long is the warranty on NEMTEK energizers?

  Unless otherwise specified, all NEMTEK energizers have a 2-year warranty from the date of sale against defects due to faulty workmanship or materials. Other fencing components typically carry a 1-year warranty.

• Can I use non-rechargeable batteries in my NEMTEK energizer?

  No, only rechargeable lead-acid batteries should be used. Using non-rechargeable batteries can cause severe damage to the unit and violate warranty terms.

• What should I do if the power LED on my energizer does not illuminate?

  Check the internal SUPPLY fuse (typically a 2 Ampere fast blow fuse). If mains power is connected but the LED is off, the fuse may need replacement.

• How do I access programming mode on the NEMTEK Merlin 4 Energizer?

  To enter programming mode, enter the 6-digit installer PIN (the factory default is 0 1 2 3 4 5) on the keypad, followed by the * 0 # keys.
