8. Re-install the DC dead front if the circuit breaker option is used.
9. Energize the DC cables.
10. Using a voltmeter, check the PV array positive leads and confirm the voltage is
positive when referenced to the negative leads. The reading should not exceed
your calculated series Voc or the 600 VDC maximum inverter input
specification.
11. De-energize the DC cables.
12. Re-install the front left access cover.

Using the Integrated Remote Disable Input

There are two remote disable inputs available to the installer in the inverter. The
inputs are located on the communications interface PCB which is located in the data
monitoring compartment.
The remote disable inputs consist of two pairs of screw terminals to which a user can
connect separate remote switches or contacts. Using the remote disable input allows
the inverter to be shut down remotely by opening a switch or set of contacts. This
feature would typically be used in conjunction with a fire alarm panel or a generator
output signal. The contacts need to be normally closed for the inverter to operate. The
customer will need to provide a 5 V, 5 mA tolerant relay, switch, or set of contacts.
