The main output of this product is capable of providing hazardous energy (240VA). Final equipment
manufacturers must provide protection to service personnel against inadvertent contact with the output
terminals.
The ventilation openings on these products must not be impeded. Ensure that there is at least 50mm spacing
between any obstruction and the ventilation openings.
The unit cover/chassis, where applicable, is designed to protect skilled personnel from hazards. They must
not be used as part of the external covers of any equipment where they may be accessible to operators, since
