Cabling the Switch
b. Negative source DC cable to the negative (- / -48V) terminal.
Positive (+) source DC cable to the positive (+ / Rtn) terminal.
Note:
Ensure power is removed from DC circuits before performing any installation actions. Locate
circuit breakers or fuses on DC power lines servicing the circuits. Turn off the power line
circuits or remove the fuses.
Wire size must comply with local and national requirements and electrical codes. Use only
copper wire.
Apply the ground connection first during installation and remove last when removing power.
Assurez-vous de pouvoir retirer des circuits en courant continu avant d’effectuer toute action
d’installation.Localiser les disjoncteurs ou fusibles sur les lignes électriques DC entretien
des circuits. Mettez hors tension le circuit ligne ou retirer les fusibles.
Calibre doit respecter les exigences locales et nationales et les codes de l’électricité. Utiliser
seulement du fil de cuivre.
Appliquer le motif connexion tout d’abord pendant l’installation et supprimer dernière lors du
retrait de puissance.
4. Replace the terminal covers as required.
