4. Press the shield clamping saddle down onto the shield of the
stripped cable until it snaps into place and fasten hand-tight.
5. Attach the cable to the cable support rail using a cable tie. This will ensure that the cable cannot be pulled out
inadvertently.
12.3.3 Connecting the Remote Shutdown
The remote shutdown enables the Sunny Central to be switched off from a distance, e.g. from a control room. The function
of the remote shutdown is similar to the stop function of the key switch.
Cable requirement:
☐ The cable must be shielded.
Requirement:
☐ The Sunny Central must be disconnected (see Section 14 "Disconnecting the Sunny Central", page 69).
Procedure:
1. Insert the remote shutdown cable in the interface cabinet (see Section 12.2 "Leading the Cables into the Interface
Cabinet", page 58).
2. Connect the cable in accordance with the circuit diagram (see Section 12.3.1 "Connecting the Cables to the
Connecting Terminal Plate", page 59).
3. Remove the shield clamping saddle from the busbar.
Supply voltage shortfall
If the supply voltage at the remote shutdown unit is between 18.5 V and 24.0 V, the Sunny Central will continue to
operate in its current operating state. If the supply voltage at the remote shutdown unit falls below 18.5 V,
the Sunny Central switches from the current operating state to the operating state "Stop".
If the temperature in the interior of the Sunny Central exceeds +60°C, the remote shutdown unit must be supplied
with a supply voltage of 20.0 V to 24.0 V to continue operating the Sunny Central in its current operating state.
Ensure that the remote shutdown unit is supplied with a constant external supply voltage of 20.0 V to 24.0 V.
