Simplified diagram of ZUP-230V power supplies.
The 230V power distribution block (ZUP) switches the power outputs of the AC-1, AC 2, AC-3 and
AC-4 external devices in accordance with their functions, while supplying the voltage from mains
(230Vac power) or from the inverter in the event of power failure. Each output is equipped with its own
fuse.
The diagram shows exemplary connection of the external device (ACTUATOR # 1) from the AC-3
output.
The suitable action of switching outputs and power is initiated independently when power failure or
it can be forced by a fire alarm signal (CSP input). The input can be operated from multiple locations
after setting the line control mode. You can also disable the line control mode, forcing a simple two-
state operation.
The correct supply of the whole packet is indicated by the green LED OPERATION.
The power supply inverter operates continuously, which reduces the time it takes to switch from the
mains to the battery operation mode. Its starting and backup operation takes place from the ZSP121N-
DR power supply output. Then the ZINW-1 connector and the corresponding yellow LED on the ZUP's
power supply packet are on.
In case of necessity of loading the inverter (e.g., when power failure), its power is switched directly
onto the battery bank. The ZINW-2 connector is connected and the corresponding red LED on the
power supply packet are on.
Such the way of operation allows for independent supervision of the battery bank; its charging,
voltage and current measurement, resistance measurement and battery circuit continuity monitoring.
The inverter is connected directly to the battery only when significant current is required. It is also
possible to completely disconnect it after discharging the battery, which prevents it from damage.
The ZSP121N-DR power supply, in addition to the functions related to supervision of the battery
and powering the electronic circuits, allows for connecting additional external devices powered with
24V (OUT1 output) and for output of the binary signal (relay outputs), general fault (GEN FLT) and
