The equipment is de-energized through its power cable (s). The power outlet
must be nearby and easily accessible.
The electrical installation of the site should be protected by devices against short
circuits.
On the PSU 125 DC, fuses F1 and F2 support currents up to 15A. They are 86V
Fast Acting. If necessary, only replace it with one of the same specifications. The
F3 output fuse
supports currents up to 15A. It is also 86V Fast Acting. If
necessary, also replace it with another one with the same specifications.
In the PSU 125 AC, fuse F1 supports currents of up to 5A. They are of Fast Acting
type, 250V. If necessary, only replace it with one of the same specifications. The
F1000
output fuse
supports up to 15A. It is a Fast Acting type, 86V. If necessary,
also replace it with another one with the same specifications.
In the situation where both PSUs are present and the power inputs are energized
and operating with voltages within the specified range, the main power input
(MAIN) will take precedence over the BACKUP power supply.
