The work required to install the necessary power and ground can be completed simultaneously with the relay-rack installation. You may elect to hire an electrician to complete the work. In general, allow two weeks from your customer commit date (CCD) to complete any stand-alone power and ground work.
- The amperage, number and type of receptacles will be determined at the site survey.
- Dedicated circuits backed up by UPS/generator systems are strongly recommended.
- For AC power, 20A, 120V AC generator-backed, AC power is typically requested.
- For DC power, if 48V DC, end user must provide +/- power leads with 2m (-6’) of slack wire coiled at the equipment location.
- You must provide adequate grounding capability in the form of 19mm (3/4”) metallic conduit from the equipment to an approved building ground.
Grounding options listed in order of preference are: building service ground, main electric box, building steel, and, lastly, a metallic water pipe which is in direct contact with the earth for 10’ or more and electrically continuous to the point where the protector ground wire is installed; a bond must be placed around any meters.
