Teltocharge Product FAQs - SPD Information

1) What is a Surge Protection Device (SPD) and why do I need one?

An SPD is a device designed to protect electrical equipment from voltage spikes. It's necessary for safeguarding the electrical components of your Teltocharge products from sudden surges in electrical power.

2) Are SPDs included in the Teltocharge product package?

No, SPDs are not included in the package and must be purchased separately.

3) Should I use an external Surge Protection Device (SPD) with my TeltoCharge product?

Absolutely. The TeltoCharge line is engineered for safety and efficiency but does not have built-in surge protection. We strongly recommend equipping an external SPD to protect your device from unexpected power surges. Implementing this measure is not just a suggestion—it is a critical step to ensure the optimal performance and durability of your TeltoCharge product against electrical fluctuations.

4) What types of SPDs are recommended for Teltocharge products?

Teltonika recommends two types of SPDs:

  • Type 1 SPD with max continuous working voltage of 275VAC.
  • Combined Type 1&2 SPD with the same voltage specifications.
    • Both must be certified according to the standard IEC 61643-111.

5) Is surge protection necessary for maintaining the warranty, and what happens if a customer declines the surge protection option?

While surge protection is not mandatory as per our regulations, it is highly advisable. Surge protection devices play a vital role in safeguarding not only the charging station but also all other electronic appliances within the premises from voltage spikes. Our stance is to urge electricians to ensure that at least one surge protection device is present in the home’s electrical system to mitigate the risk of surge-related damage. If a customer opts not to install surge protection and subsequent damage occurs due to a power surge, this may affect the warranty coverage of the charging station. We recommend the installation of surge protection as a preventative measure for comprehensive electrical safety.

Teltocharge Product FAQs - RCD Information

1) What is an RCD and why do I need it for my Teltocharge product?

An RCD, or Residual Current Device, is a safety device that automatically cuts off the electric supply when it detects an imbalance in electricity flow and current increase on Protective Earth wire between live and neutral wires. This is crucial for preventing electric shocks and fires when using your Teltocharge product.

2) What are the installation options available for the RCD?

There are three installation options provided, with varying requirements for tripping current, overcurrent protection, and compliance with specific IEC standards. More details can be found here.

3) Is the RCD included in the Teltocharge package?

No, the RCD is not included in the package and must be purchased separately. Please consult with your installation specialist.

4) Do I need an additional RCD if my house grid already has one installed?

If the house grid already has an RCD pre-installed on the same supply line as EVSE, an additional one is not required.

5) Is a Type B RCD mandatory for installation as per the manual, and will using a Type A RCD instead invalidate the warranty?

Our company prioritizes safety above all. Therefore, we strongly recommend the installation of an external Type B RCD when using our device. The Type B RCD provides comprehensive protection against all types of residual currents that might not be detected by a Type A RCD. While Type B RCDs are typically pre-installed in modern electrical grids, their absence could significantly increase the risk of harm to individuals and property. In the unfortunate event of an accident attributable to the use of a Type A RCD, the warranty we offer may not cover the damages, as the use of a Type B RCD is a critical part of our safety recommendations.

6) What do we have integrated in our product if it is not an RCD?

Inside of our product, there is protection working by Residual Current Monitoring (RCM). It detects if 30mA AC or 6mA DC leakage was observed and notifies the processor to switch off the relays.
