3.0 Receiving and Installation
3.1
Receiving
•
Upon receipt of the DBS controller, immediately unpack it and look for any shipping damages.
If any shipping damages are encountered, file a claim with the freight carrier within 15 days of
receipt.
•
Verify that the ratings sticker on the DBS chassis matches the motor’s HP, current, and voltage
rating for the installation.
•
Check for loose mechanical connections and assemblies, and wires which may have
broken or loosened during shipping and installation.
•
Manually exercise all electromechanical devices to make sure they work freely.
3.2
Mounting and Cleaning
•
When mounting a “stand-alone” DBS controller, make sure there is sufficient clearance (12"
minimum) around the enclosure for cooling, wiring, and maintenance purposes.
•
Make sure that the manner in which the controller is mounted meets the latest requirement of
the National Electrical Code and any other local code requirements for working space (NEC
Code Articles 110-13 and 110-16).
•
Freestanding controllers should be securely mounted to a flat, level, base using mounting holes
provided. Shim base of enclosure to prevent racking or door misalignment.
•
Wall-mount type controllers should be securely mounted to a flat, vertical surface or framework
using mounting holes provided using hardware that will adequately support its weight. Shim
rear of enclosure to prevent racking or door misalignment.
•
When drilling or punching holes in the enclosure, cover the electrical components to prevent
metal filings and debris from causing short circuits or reducing electrical clearances.
WARNING!
Remove all sources of power before cleaning controller.
•
After mounting and wiring is completed, thoroughly clean and vacuum the enclosure, and make
sure that all filings, metal chips, and other materials are removed before start-up.
