150V Ground Fault Protection Device Installation and Operation Manual

Step 3. Crimp the supplied ring terminals on the

breaker side ends of the (+) and (-) breaker<->controller

conductors. Connect breaker side (+) wire to post (1)

(line side), and breaker side (-) wire to post (3) (load

side) using the supplied hardware (see Figure 6).

Step 4. Connect controller side breaker<->controller

wires to controller (+) and (-) solar terminal lugs. Close

GFPD-150V breakers.

Step 5. Run the supplied (+) and (-) GFPD power ter-

minal wires through a convenient knock-out for connec-

tion to voltage source described in Step 9.

Step 6. Position and fasten GFPD-150V / Breaker

assembly into place in the GFPD-150V box.

Step 7. Run (+) and (-) controller<->battery wires

through right knock-out, and connect to controller’s (+)

and (-) battery terminal lugs.

Step 8. Wire battery (+) through battery disconnect to

battery (+) terminal, and connect. Connect battery (-)

wire to battery (-) terminal.

Step 9. Using supplied in-line fuse holder and 5A fuse,

install fuse 6 to 12 in. from (+) battery terminal.

Connect (+) and (-) wires from GFPD-150V to external

10-72V source (usually system battery) (+) and (-) termi-

nals.

NOTE: Do not tap from a lower voltage battery

bank section that is part of a higher voltage bank -

an imbalance will occur.

WARNING: The PV system must be properly grounded

AVERTISSEMENT: Le système PV doit être correcte-

ment mise à la terre.

Step 10. Ground the PV system properly by electrically

connecting each individual metallic component such as

PV frames, conduit, combiner boxes, controllers, invert-

ers, GFDIs, and any other dead metal to Earth ground.

Locate the system ground on the battery side at either

a battery (+) or battery (-) terminal depending on sys-

tem polarity. Install the grounding system in accor-

dance with local codes and regulations.

Step 11. Close battery disconnect switch.

Step 12. Close solar disconnect switch.
