Using the Defender ZE210022 transformer is quite straightforward. First, make sure it's placed on a stable surface. Since it doesn't come with a plug or cable, you'll need to connect your own power source. The 4 x 16A and 2 x 32A outlets allow you to connect different electrical devices. When handling the transformer, use the collapsible lifting handles to move it safely. Be careful not to overload the transformer; keep in mind the intermittent rating of 10000VA and continuous rating of 7000VA. For maintenance, check the easily replaceable bolted feet regularly to ensure they're in good condition. Also, since it's centre - tapped to earth, don't tamper with this grounding feature. Keep it in a dry and well - ventilated area as it's an air - cooled unit.
