Installing the inverter
Authorised electrician
Variants: Spring terminal (Powador 2002-3002)
7. Insert screwdriver into the spring terminal and press it lightly upwards.
8. Insert AC lines completely into the spring terminal as specifi ed by the
labels. (Figure 15 on page 21)
9. Move screwdriver to the initial position.
10. The spring terminal is closed and the cable is held in place.
Variants: Screw clamp (Powador 4202-6002)
11. Connect lines to the PCB terminal as specifi ed by the labels (Figure
15 on page 21) with the specifi ed tightening torque (chapter 7.2 on
page 18).
12. Check that all connected cables are securely fi tted.
13. Tighten the cable fi tting.
» The inverter is now connected to the power grid.
ACTIVITY
Cables on the AC screw terminal (Powador 4202-6002 only) must be tightened to the specifi ed
torque at regular intervals (see chapter 7.2 on page 18).
NOTE
An AC-side disconnection unit must be provided during the fi nal installation stage. This disconnec-
tion unit must be installed so that it can be accessed at any time without obstruction. If a residual
current circuit breaker is necessary due to the installation specifi cation, a type A residual current
circuit breaker must be used.
7.2.2 Connecting the PV generator
A suitable crimping tool must be used to connect the stripped DC leads to the MC-4 coupling plug and coupling
socket (solar plug connection).
Connect the MC-4 coupling plugs to the 3 DC positive and the 3 DC negative mating parts on the underside of the
housing (see Figure 16 on page 22).
NOTE
Connected PV modules must be dimensioned for the DC system voltage in accordance with IEC 61730
Class A, but at least for the value of the AC grid voltage
DANGER
Risk of fatal injury due to contact voltages.
› During installation: Electrically disconnect the DC positive and DC negative from the protective
earth (PE).
Removing the plug connection without fi rst disconnecting the inverter from the PV generator may
lead to injuries and damage the inverter.
› Disconnect the inverter from the PV generator using the integrated DC isolator switch.
› Remove the plug connector.
