CAUTION! The arrangement of contacts at the figure 7 shows a potential-free status of the relay, 
which is equivalent to a state with no voltage at any of the AUX1 ÷ AUX8 outputs. 
•  TAMPER – output indicating enclosure opening: - volt free contact input indicating the status of the 
power supply doors, PSU closed: contacts closed (NC), PSU open: contacts open (NO). 
4.  Service and operation. 
4.1. Overload or short-circuit of the power supply output. 
The  AUX1÷  AUX8  outputs of  the PSU  are protected  against  short-circuit  and overload  by
melting fuse 
inserts or PTC polymer fuses. (The Fx / PTCx jumper position determines which fuse is used). If the power supply 
load  current  exceeds  Imax.  (110%  ÷  150%  @  25°C  of  t he  PSU  power),  the  output  voltage  is  automatically 
disconnected, which is indicated by turning off the green LED. 
If the PTC polymer fuses are used, disconnect the load from the power supply output for approximately 1 
minute to restore output voltage. (the time needed to cool down the PTC fuse). In case of melting fuse activation, it 
should be replaced with a fuse of the same type and of the same rated current. 
4.2. Battery operation 
In case of mains power loss, the unit will instantly switch to battery operation. 
The power supply is equipped with a discharged battery disconnection system. If 
the battery voltage has dropped below 39V during the battery operation, the battery will be 
disconnected. 
4.3. Maintenance. 
All  maintenance  procedures  can  be  performed  after  disconnecting  the  power  supply  from  the  power 
network.  The  PSU  does  not  require  any  specific  maintenance;  however,  its  interior  should  be  cleaned  with 
compressed air if used in dusty conditions. The battery status should be checked periodically. (battery capacity 
loss, too high internal resistance) batteries should be replaced. In case of fuse replacement, use only compatible 
replacement parts
