A 48V DC mains power distribution system feeding the PSU must be classified as a “SELV” (according to 60950) or as
“ES1” (according to 62368).
A 60V DC mains power distribution system feeding the PSU must be classified as a “SELV/TNV-2” (according to 60950)
or as “ES2” (according to 62368).
Please observe the maximum working voltage (described in the table below).
Maximum Working Voltage
DC PSU Input Earth 72Vrms
DC PSU Output Internal circuits of .edge 72Vrms, 93Vpeak
The branch circuit protection feeding the PSU must be protected by a fuse or circuit breaker rated with 100A maximum.
We recommend using an 80 A protection device.
The breaking capacity must fit the requirements of the DC mains power distribution system.
The wires that feed the DC PSU must offer a cable cross-section at least of AWG 10 (5,2 mm²). Please check whether a
higher cable cross-section is required (based on the local standards and installation situation).
Use stranded wire with ring or fork terminals.
Take care that if a strand of a conductor should escape, it does not make contact with any other part of the device.
A disconnect device must be provided between the DC mains power distribution system and the PSU.
The disconnect device must be rated for the DC voltage of the DC mains power distribution system and must provide
sufficient clearance and creepage distances.
The DC mains power must be disconnected from the device, using the disconnect device, before the feeding wires are
disconnected at the DC PSU.
The input terminal block has not been evaluated for current interruption purposes.
