CP-721-FPV
Voltage relay
for photovoltaic systems
Do not dispose of this device in the trash along with other waste! According to the Law on
Waste, electro coming from households free of charge and can give any amount to up to
that end point of collec� on, as well as to store the occasion of the purchase of new equip-
ment (in accordance with the principle of old-for-new, regardless of brand). Electro thrown
in the trash or abandoned in nature, pose a threat to the environment and human health.
Purpose
The CP-721-FPV 1-phase voltage relay is dedicated for photovol-
taic systems. In the event of detecting an excess of the preset
voltage level, the output relay will switch on, with the help of
which it is possible to switch on an additional consumer (e.g.
a boiler), thus increasing the self-consumption of energy in the
domestic installation and reducing the risk of the photovoltaic
inverter switching off due to excessively high mains voltage.
Functions
» Output circuit switched on when voltage is exceeded, swit-
ched off when voltage decreases;
» Precise adjustment of switching voltage;
» Programmable delay for relay activation and deactivation;
» Programmable voltage hysteresis for relay deactivation;
» Direct control of loads up to 16 A;
» LED display for continuous voltage monitoring.

  • Page 1 Purpose The CP-721-FPV 1-phase voltage relay is dedicated for photovol- taic systems. In the event of detecting an excess of the preset voltage level, the output relay will switch on, with the help of which it is possible to switch on an additional consumer (e.g.
  • Page 2 Functioning The CP-721-FPV relay continuously monitors the voltage in the mains supply, the measured voltage value is indicated on the display on the front of the device. If the voltage is detected to exceed the preset level "Uon", the overvoltage time countdown starts.
  • Page 3 A diagram of how the relay works is shown in the figure below: The relay is equipped with thermal protection to prevent the device from exceeding a safe internal temperature (e.g. due to excessive load current). If this is triggered, the internal relay switches off and the display shows the message: The condition for returning to normal operation is:...
  • Page 4 Settings The CP-721-FPV relay allows 4 parameters to be set by the user: Settings Parameter Function Step Relay activation 245 V 265 V 1 V voltage Relay deactivation 1 V 10 V 0.5 V voltage hysteresis Delay from overvoltage to relay 0 s 999 s 1 s activation Delay from voltage drop to relay 0 s...

    Change of settings scheme » To enter the settings mode of the relay, press and hold down simultaneously the "+" and "–" buttons located on the front of the relay. The entry into the settings mode is signalled by the display of the name of the first parameter to be edited (Uon).
  • Page 6 When installing the relay for 3-phase photovoltaic instal- lations, it is recommended to connect the CP-721-FPV relay to the phase with the highest voltage overshoot, or to use a separate relay for each phase and control the load via an additional phase switch. An example wiring...
  • Page 7 If there is a risk of simultaneous overvoltage on more than one phase, it is advisable to use a separate CP-721- FPV relay for each phase to be monitored and for each relay to switch its own load. Technical data power supply 150÷300 V AC contact...
  • Page 8: Warranty
