5.4.6.3 Shutdown contact 2 – X511
The shutdown contact 2 (X511) allows the inverter to be remotely shut down via an
external break contact. The function is similar to the one of shutdown contact 1, but the
separation from the grid is not made directly via the supply voltage of the AC contactor
K1. It is controlled by software via the inverter’s control unit. The inverters remain locked
until the external break contact is reclosed. In addition, the status message “Shutdown
2” is displayed. The shutdown 2 is inactive, if EN1 and EN2 (EN12) are short-circuited by
a bridge (condition at the time of delivery). The shutdown 2 is active if the contact pair
EN12 is open.
5.4.6.4 Alarm contact – X501
The alarm contact (X501) is used to display the status of the generator connection box
MaxConnect plus in the graphics display. For this purpose use a two-wire cable to connect
the contacts of the potential-free fault alarm output of MaxConnect plus to the STM and
GND contacts on the inverter’s terminal block. As soon as the STM and GND contacts are
short-circuited, the inverter display shows the status message “Warning MaxConnect”.
5.4.6.5 Connection PAS - X2201
Interface for the connection of the potential equalization set (PAS). Use the cable supplied
with the potential equalization set.
NOTE
The potential equalization set (PES) may only be used for stations configured for single
MPPT operation. Contact the SolarMax Service Center, if you want to connect the
potential equalization set.
