1. SAFETY CONSIDERATIONS

1.1

Earthing of Equipment

Cell Enhancers supplied from the mains must be connected to grounded outlets and earthed in conformity with appropriate local, national and international electricity supply and safety regulations.
AFL recommends that all other hardware enclosures and electrically conductive metalwork within operator reach of the cell enhancer cabinet (enclosing the PSUs) be grounded to the same earth to prevent hazardous differential voltages between equipment which could result in electrocution.
This arrangement of grounding and safety earthing has always been implemented by AFL and meets good RF-engineering grounding practice, thus preventing any risk of electrocution when touching both the modules and cabinet or due to the leakage from the PSU input filter. The use of a common ground for the cabinet and AC supply input will have no detrimental affect on the overall electrical or EMC performance of the equipment.

1.2 Electric Shock Hazard

Electrical shocks due to faulty mains driven power supplies. Whilst ever potentially present in any electrical equipment, such a condition would be minimised by quality installation practice and thorough testing at:
a) Original assembly b) Commissioning c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies can be dangerous because of the possibility of substantial arcing. Always switch off during disconnection and reconnection.
