Due to the sensitivity of customer equipment, it is highly recommended to use trained technicians for installation and product setup. Most of the UPS up to 3kVA are plug & play and can be installed by the customer itself. But for higher capacity UPS devices or the ones with external batteries, it is necessary that trained technicians do the installation. Installation and setup services are completely free for the products which are not plug & play for the first time at all locations in Iran.
After delivery of the product, the following proceedings should occur for the installation:
1. Calling (021) 66 72 3972 (Ext. 2) in order to schedule installation and setup appointment by our technicians. (This can also be done by contacting the sales department)
2. Arrival of our technician to the installation site, observe the location and prepare the initial conditions for the proper installation

Inspection and service includes overall inspection of all installed equipment (UPS, batteries, etc.), continuous supervision of overall operation of the system after installation. Inspection and service of equipment using professional technicians is very important regardless of the equipment and the company that the customer is working with. If a component that is about to become malfunctioned or is near the end of its fatigue life is not repaired or replaced, it will probably cause damage to other components which might cause irreversible damages to the overall system. Inspection and service of equipment on schedule will extend the life of batteries and the UPS. Therefore, it is recommended to do the inspection and service minimum of four times a year through professional technicians due to economical and safety reasons. Zener engineering co. service center can provide inspection and service for your equipment and preventive maintenance for longer equipment life at the shortest possible time using our professionally trained technical staff.
