7. Remove the internal shield and set it nearby, outside of the PSU enclosure. You can now
access the hole for the power cable and the M20 blanking plug covering the hole.
8. Remove the blanking plug. Install suitable (metal) conduit in place of the blanking plug.
Secure the conduit as recommended by the conduit manufacturer.
Caution!
Only installations with conduit meet UL standards. If you choose to use a power cord without
conduit (not recommended), fit the 1/2 in. NPT cable gland (supplied) in place of the
!
blanking plug. Note: It is easier to fit the power cord through the cable gland outside of the
enclosure, and then attach the gland to the enclosure. Ensure that the cable glands have
sufficient room to allow for the cables to enter (approximately 60 mm on either side of the
enclosure).
9. Prepare the power cable as needed, and then feed the cable into the enclosure.
10. Connect the Live and Neutral cores to the correct screw terminals on terminal block HD1
as identified in the table below and printed on the PCB. Observe polarity and voltage.
