TriStar MPPT-600V-TR Operator's Manual
Use a copper wire to connect the grounding terminal in the wiring box to earth ground. Per NEC
690.45 and NEC Table 250.122, the minimum size for copper grounding wire is:
(1) TriStar MPPT 600V unit
60A
10 AWG ( 8 mm
2
)
Also follow any additional local grounding code / regulations that may apply.
The grounding terminal is identified by the ground symbol adjacent to the terminal and shown
below:
Do not connect the system negative conductor to this terminal. NEC requires the use of an
external ground fault protection device (GFPD). The TS-MPPT-600V-TR-GFPD affords this
protection, and installation is detailed in the GFPD-600V product manual. In tradtional GFDI
devices, the system electrical negative should be bonded through a GFDI to earth ground at one
(and only one) location. The grounding point may be located in the solar circuit or the battery
circuit.
WARNING: Risk of Fire
DO NOT bond system electrical negative to earth ground at the controller. Per NEC
requirements, system negative must be bonded to earth ground through a GFPD at only
one point.
AVERTISSEMENT : Risque d’incendie
NE LIEZ PAS le côté négatif du système à la mise à la terre au niveau du contrôleur.
Selon les exigences du CNE, le côté négatif du système doit être mis à la terre par un
GFPD à un seul point.
