DM504A Grounding the Product When installed in the power module, this product is grounded through the grounding conductor of the power cord. To avoid electrical shock, plug the power cord into a properly wired receptacle before connecting to the product input or output terminals. Upon loss of the protective ground connection, all accessible con ductive parts (including knobs and controls that may appear to be insulating) can render an electric shock.
Polarity indication is automatic. Per f orm anc e Condi tions The electrical characteristics are valid only if the DM 504A has been calibrated at a temperature between · c and +25 ·c and is operating at an ambient temperature between 0 c and +50 ·c.
