ACTION

The ground for the DC input is provided by the integral

GFDI circuit. DC input should not be grounded external

to the unit.

Circuit board fuse

The power section has two internal circuit board fuses. These

are labelled F801 or F861 on the circuit board.

F801:

Model: 179120 5x20 time-lag 250VAC/0.4A

Manufacturer: SIBA

F861:

Model: TR5-Fuse series 372 250VAC/125VDC/1A time-lag

Manufacturer: Littlefuse/Wickmann

WARNING

For continued protection against risk of ﬁre, replace

only with same type and ratings of fuse.

5.5 Connecting to the Public Grid

The inverter can be installed on the following grid-types:

120°

120°120°

240V

120V 120V

Figure 5.11: 240 V Delta: 120 V Stinger

Country setting on the display: USA 240 V

NOTE

A screwdriver (slotted, 3.5 mm) is to be used for the terminals

in the inverter. Put the screwdriver into the intended cut-out.

Press the screwdriver upwards a bit. Put the cable into the

spring terminal. Put the screwdriver back into the original

position. Remove the screwdriver. The spring terminal is

closed and the cable is held in place. Lightly pull on the

wire to be sure it is secure.

CAUTION

Be sure the inverter is conﬁgured for the proper DC

grounding conﬁguration of the system.

CAUTION

The voltage of the solar generator must be

measured before connecting the DC leads to the

inverter terminals. The DC voltage must not exceed

the max. generator voltage because this would

destroy the unit.

ACTION

Before connecting the PV generator to the blueplanet, check

that the PV generator is not grounded.

– Measure the DC voltage between the protective ground

(PG) and the positive lead and between the protective

ground (PG) and the negative lead of the PV generator.

– If stable voltages can be measured, this indicates a

ground fault in the PV generator or its wiring. The ratio

between the measured voltages gives an indication as to

the location of this fault. Rectify this fault before taking

any further measurements.

– Measure the electrical resistance between the protective

ground (PG) and the positive lead and between the

protective ground (PG) and the negative lead of the PV

generator.

– Low resistance (< 2 MΩ) indicates a high-impedance

ground fault of the PV generator, which must be ﬁxed

prior to continuing with the installation.

Once the wiring in the connection box is installed the protective

cover over the terminals must be secured using the included

screws and must not be opened unless the switch is in the off

position, the AC breaker is in the off position, and the PV array

is powered down with an opaque cover or other equivalent

method to assure there is no DC voltage present in the box.

The connection box should be considered the same as any

other external DC disconnect switch which has live conductors

inside.
