Safety Class of Protection
The unit is designed for the following parameters : Material Group IIIb, Pollution Degree 2,
Overvoltage Category II, Class 1 (earthed), Indoor use. The unit is considered as fixed and
rated IPX0. The CPFE500F-12 and CPFE500F-24 are classed as having SELV outputs.
The CPFE500F-48 is classed as having a NON SELV output. All outputs are capable of
providing hazardous energy (>240VA). The final equipment should provide protection to
service personnel against inadvertent contact with the PSU output terminals.
Installation
This product is designed for use within other equipment which restrict access to authorised
competent personnel only. The unit covers/chassis must not be made user accessible.
The appliance may be mounted in any orientation except inverted (baseplate uppermost).
The customer has to ensure the baseplate temperature remains below certain limits.
Horizontal orientation input 90-149V baseplate temperature limited to 75°C.
Horizontal orientation input 150V or greater baseplate temperature limited to 85°C.
All other orientations baseplate temperature limited to 85°C.
With open frame version, any orientation is permitted at 85°C baseplate temperature.
The mains input connector is not acceptable for use as field wiring terminals.
The appliance must be securely mounted and the baseplate properly bonded to the main
protective earth contact before any connection to AC mains supply is made.
The ventilation openings must not be impeded – ensure a space at least 5cm between any
obstruction and the ventilation openings.
