Installation Guidelines for Cafe Power Gen Set

Installing a cafe power generator set requires careful considerations and adherence to specific guidelines to ensure proper functionality and performance. This article provides an in-depth look at the installation process, covering various topics such as site selection, foundation preparation, unloading and placement, earthing, exhaust piping, power cabling, and battery capacity and cable size.

1. Introduction

To ensure the smooth operation of a cafe power generator set, proper installation is of utmost importance. This video will guide you through the installation guidelines for Tafe power gen sets, covering key aspects to consider during the installation process.

2. Site Selection

Choosing the right site for installing a cafe power gen set is crucial for its efficient functioning. There are several options for placing the gen set, including open areas on RCC or PCC foundation, inside a room or basement of a building, or on the rooftop. Each option requires specific considerations for proper ventilation and space requirements.

2.1 Open Areas on RCC or PCC Foundation

Placing the gen set in open areas on an RCC or PCC foundation provides easy access and maintenance. Ensure there is sufficient cross airflow with cutouts for fresh air inlet and hot air discharge. It is essential to maintain a free space of 1 to 1.25 meters around the gen set to ensure proper ventilation and optimize performance.

2.2 Inside Room or Basement of a Building

If you decide to install the gen set inside a room or basement, proper ventilation arrangements must be made. Ensure there are proper openings for fresh air inlet and hot air discharge in the closed area. Ducting and the installation of sucker and blower fans can help achieve adequate ventilation. Remember to maintain free space around and above the gen set for optimal airflow.

2.3 Rooftop Installation

Rooftop installation requires careful planning and consideration of structural design. The weight of the gen set must be supported by columns and beams through a proper foundation. Using MS channel on the column of the building can cater to the load of the gen set. Tafe power gen sets come with a pre-installed MS sheet at the bottom of the canopy, making them suitable for rooftop installation.

3. Cross Airflow and Ventilation

Establishing proper cross airflow and ventilation is essential for the efficient operation of the cafe power gen set. Ensure that there is a suitable distance between multiple gen sets and maintain a minimum of 1.5 to 2 meters of free space between them. In parking area and basement installations, it is crucial to maintain cross ventilation for fresh air inlet and hot air discharge to prevent overheating.

4. Parking Area and Basement Installation

For installations in parking areas or basements, it is vital to ensure proper ventilation for the gen set. This can be achieved by creating suitable openings for fresh air inlet and hot air discharge. Maintaining cross ventilation is crucial to prevent the buildup of heat, which can adversely affect the performance and lifespan of the gen set.

5. Foundation Preparation

The foundation is one of the key factors that contribute to the successful operation and life of the gen set. Proper preparation of the foundation is crucial for stability and performance. The length and width of the foundation should be 600 millimeters more than the size of the DG set on each side.

5.1 PCC Foundation

For preparing a PCC foundation, use a mixture of cement, gravel, and sand in the ratio of 1:2:4. This ensures the foundation's strength and durability. The genset foundation should be 150 to 250 millimeters below the ground level, depending on the soil condition. The foundation should be water-leveled and evenly flat for optimal stability.

5.2 RCC Foundation

For an RCC foundation, iron bars of suitable size should be used. The same mixture of cement, gravel, and sand should be utilized. The foundation should be strong enough to support 1.5 to 2 times the total weight of the gen set. It should be 150 to 250 millimeters above the ground level to provide adequate space for ventilation.

5.3 Rooftop Installation

Rooftop installation requires specific planning and structural design considerations to ensure the gen set's stability. The weight of the gen set should be transferred to columns and beams through a proper foundation. Using MS channel on the column of the building can effectively cater to the load of the gen set. The MS sheet provided with Tafe power gen sets at the bottom of the canopy facilitates rooftop installation.

6. Unloading and Placement

Unloading and placing the gen set correctly is crucial to prevent any damage and ensure its proper functioning. Use proper lifting tackle with a nylon sling for unloading the gen set, avoiding any damage during the process. Place the gen set exactly in the middle of the foundation to distribute the weight evenly. Ensure a suitable distance from the gen set for safety purposes.

7. Earthing

Earthing of the alternator neutral and genset body plays a vital role in grounding fault current and ensuring the operator's safety. There are different types of earthing, including copper plate earthing or chemical earthing. The recommended length and width of the earthquake are 1000 millimeters and the depth is 1800 millimeters.

7.1 Alternator Neutral and Genset Body Earthing

The neutral and genset body of the gen set should be earthed according to local regulations. The distance between two Earth bits should be a minimum of 2 meters. The neutral Earth bits and body Earth bits should be located on opposite sides of the canopy. It is crucial never to interconnect the body and neutral earth.

7.2 Types of Earthing

Commonly used types of earthing are copper plate earthing and chemical earthing. For copper plate earthing, the length and width of the copper plate should be 500 millimeters, and the thickness should be eight millimeters. Chemical compound, charcoal, salt, and soil are used in the earth pit to ensure proper grounding.

8. Exhaust Piping

Proper exhaust piping is essential for the safe operation of the gen set. If an extension of exhaust piping is required, it should be done with support and clamping. Follow Tafe power guidelines for extending the exhaust pipe, maintaining the proper diameter and height. For multiple bends in the exhaust pipe, increase the pipe diameter by 0.5 inches for each additional bend.

9. Power Cabling

Ensure proper power cabling for connecting the gen set to the electrical system. Use power cables of recommended size and proper gland and lugs. It is essential to ensure proper crimping of lugs with the cable and firm tightness of power cable nuts at the terminals to avoid any loose connections or electrical issues.

10. Battery Capacity and Cable Size

Select the recommended size of battery cable with proper lugs and terminal connectors. The capacity of the battery should match the gen set's rating for optimal performance and functionality.
