Connecting Mains to the Panel’s PSU
The PSU is equipment and MUST BE EARTHED.
The panel’s PSU is a mains to regulated DC power supply providing 5A @
24Vdc nominal. Combining the functions of a PSU, battery charging unit
and battery monitoring unit, it is fully compliant with EN 54-4/A2.
Remove the PSU’s ‘small’ protective cable cover and terminate the mains
cable at the power supply’s PCB connector block CONN1 (see Photo 1
right & Figure 9 below). After terminating, refit and secure the small cover.
CAUTION: Do not connect mains to the PSU until the installation
is complete and the panel is ready to be tested
.
One method of
isolation is to open and lock off the panel’s mains isolator.
