Safety
All power supplies must be installed correctly in a controlled environment which restricts access to any unauthorised
personnel. Equipment and system manufacturers must protect service personnel against unintentional contact with the output
terminals.
Hazards
If series and/or parallel combinations of outputs exceed safe voltage and/or energy levels, the final equipment manufacturer
must provide appropriate protection for both users and service personnel.
Health and safety
To comply with section 6 of the health and safety at work act, a label that is clearly visible to service personnel must be placed
on the final equipment, which warns that surfaces of the power supply may be hot and should not be touched when the
product is operating.
Fusing
The power supply has two internal single pole fusing, one on each of the input section L (Live) line.
Servicing
The power supply contains no user serviceable parts. Repairs must be carried out by authorized personnel only. Contact
Roal
