Rice Lake DWM-IV Weighmeter Standard Operators Manual - Manual (Page 9)

Installation Requirements
Maximum performance is guaranteed only when installation of the scale system is
performed by a qualified scale technician. For best performance, the AC mains supplying
the scale system must be an isolated circuit free from other loads and not in close
proximity to inductive or SCR controls.
WARNING: THIS SCALE MUST BE OPERATED FROM AN AC POWER SOURCE
THAT PROVIDES AN EARTH GROUND FOR THE SCALE CHASSIS TO ENSURE
SAFE OPERATION AND PROPER PERFORMANCE. THE POWER CORD IS THE
POWER DISCONNECT DEVICE. CARE SHOULD BE TAKEN NOT TO BLOCK
ACCESS TO THE OUTLET IN CASE OF AN EMERGENCY.
Unpacking and Inspection
Remove the weightmeter display from its shipping container. Discard the protective
materials. Do not plug the meter into an AC voltage source until completing the
inspection of the instrument. With a proper screw driver, loosen the screws holding the
lid clasps in place. Open the lid and visually inspect to make sure there are not signs of
shipping damage such as broken wires, loose components, or fractured printed circuit
boards. This visual inspection is necessary if a shipping claim needs to be processed.
Every care has been taken to minimize potential damage that could occur if rough
handling is experienced in transit.
