1 Read This First Involar‟s new product “eGate” acts as the power interface (PI) to the utility grid. It is a separate device installed at the coupling point to the utility grid to provide the safety functions such as over/under voltage, over/under frequency, active anti-islanding as well as lightning protection.
Page 5: Safety Symbols
2 Safety Symbols Warnings and cautions indicate possible dangerous conditions that can occur if instructions are not carefully read and followed. Please read the following safety symbols and important safety instructions. DANGER The DANGER symbols in this manual and on the eGate ndicates a hazard with a high level of risk which if not avoided, will result in death or serious injury.

Page 8: Technical Competence
Involar require using only genuine replacement parts, manufactured or sold by Involar for all repairs or replacements. Read carefully through each step in every procedure before commencing installation; any exceptions may result in a failure to properly and safely complete the installation.
Page 9 The installation should only commence if there is a written permission to install the designated components. WARNING: IMPORTANT: the input AC voltage of the INVOLAR eGate shall not exceed the rated voltage; higher voltage may cause permanent damage to the device. It contains no user serviceable and INVOLAR-eGate Warranty parts.
