UPS as standard, as well as remote monitoring and diagnosis. But it’s always best to check those T&Cs. Never be afraid to question your maintenance provider – realising down the line that that your cover does not include a battery replacement, for example, can be both costly and inconvenient. Agreements are available either in or out of warranty, although be aware that the ‘out of warranty’ costs can rise. Best practice would be to request a price from your UPS supplier for a fixed price maintenance plan. u se a t h ird pa r ty ma inte na nc e provi der, ma ke s ure to c h e c k t hat w h oever ma inta in s y o u r equ i pment is full y tra ine d . To give customers access to fully trained engineers, Riello UPS runs a Certified Engineer Programme which clearly lists fully qualified engineers who have complete access to spare parts. To achieve this status, engineers must successfully complete thorough training on the commissioning, maintenance and servicing of Riello UPS products with regular reassessment. Three: Get the cover you need When agreeing a maintenance plan, make sure you know what it includes. Most maintenance plans cover regular preventative engineer visits, firmware updates and fully comprehensive cover Looking for extra peace of mind? Riello Connect is a remote monitoring ser vice designed to increase resilience and downtime of your mission critical equipment. Trained Riello UPS technicians continually monitor your UPS and battery systems, spotting problems before they result in a loss load. In the event of an alarm, an SMS or email notification will be sent to your first response contact and our technician will investigate the problem. Four: Timing is everything… UPS maintenance plans are designed to provide more comprehensive cover than a warranty and a guaranteed emergency response time; defined in either working or clock hours. With Riello UPS for example you can choose between silver (12 working hours), gold (eight working hours) or platinum (same day, four clock hours) maintenance plans. These are guaranteed response times and not simply best endeavours. You should also look at guaranteed ‘fix times’ in your contract – it’s all very well for an engineer to respond within a stated time eg. four hours but it may not be fixed for another week. At Riello UPS, we’re upgrading our platinum contracts to include a guaranteed four-hour response and eight-hour fix. Having these measures in place means you’ll negate the cost and inconvenience of unplanned downtime, and enjoy the peace of mind that comes from emergency call out, free on site repair or swap out and planned battery replacements. Get your UPS plan in place Did you know that in a data centre, two thirds of downtime events are preventable, with insufficient maintenance being one of the major causes? With this – and the fact that your UPS will at some point in its working life require component or parts replacement due to wear and tear – in mind, it’s safe to say your best line of defence is to have a comprehensive maintenance plan in place. This will not only give Did you know? Three smart ways you can maximise your UPS Using UPS as a frequency conver ter The UPS can also be deployed as a frequency converter allowing conversion between 50Hz and 60Hz. The input of the UPS will accept anything from 48Hz-52Hz and the output can be selected to either 50Hz or 60Hz. If you combine an output of the UPS with a step-down transformer, you can easily simulate American electrical supply conditions, which is ideal for testing equipment that may be used in export applications or requirements. As with using the UPS as a power conditioner, you can utilise this feature with or without batteries. On the output side, the transformer must be matched to the rating of the UPS. On the input side, the transformer needs to be oversized to cater for input power factors, battery charging and operating losses. When using the UPS as a frequency converter, the static bypass facility is inhibited. Using UPS as a voltage optimiser The UPS is a clever device which also works to constantly regulate the electricity supply to get precisely the voltage required. It works to reduce the mains power supply of incoming voltage so that it matches the electrical voltage level needed by equipment on site. The output tolerance is normally 230V but using the UPS, it is possible to set the voltage to a specified amount, for example, 215V, 218V. Optimising the voltage for the data centre means you will be maximising efficiencies. Using UPS to store energy Traditionally, the UPS has only been used on critical loads within the data centre with other services such as air handling relying on a generator for emergency power. But there is now the possibility to use Lithium ion (Li- ion) batteries with the UPS. Li-ion batteries have a much greater power density, allowing longer autonomies and a faster rate of recharge without sacrificing valuable space. It can effectively act as an energy accumulator which can be used in power outages or to feed power back to the National Grid on demand. Combine with renewable energy technologies, such as wind and solar power, and you can have a very green power solution. you the peace of mind of having access to technical expertise, but essentially will save you money by ensuring you maximise the lifespan of your technology. Having a solid maintenance plan in place is key to raising levels of uptime and will also give your UPS a longer lease of life. April 2017 | 35
