Safety
Connecting DC
cables Remove contact protectors
Feed the DC cable into the inverter, observing the bending radii specified by the cable
manufacturer
Strip at least 25 mm of insulation from the DC cable
Align the DC cable with the DC connections
3 - Push the DC terminal over the
DC cable
- Push the DC terminal up and over the
DC connection and the bare end of the
cable
- Tighten the DC terminal:
6 mm Allen key
Tightening torque = 25 Nm
- Repeat this process for every DC cable
4 - Place the DC cable in the clamp of the
strain-relief device
- Attach the clamp of the strain-relief de-
vice to the rail
- Secure the DC cable with the clamp of
the strain-relief device
- Repeat this process for every DC cable
Fit the contact protectors
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC
voltage from solar modules that are exposed to light.
-
Make sure that both the AC side and the DC side of the inverter are de-ener-
gised before carrying out any connection work.
- Only an authorised electrical engineer is permitted to connect this equipment
to the public grid.
CAUTION! Risk of damage to the inverter as the result of incorrectly tightened
terminals. Incorrectly tightened terminals can cause heat damage to the inverter
that may result in a fire. When connecting AC and DC cables, ensure that all the
terminals are tightened to the specified torque.

NOTE! Different openings are available on the rail for attaching the clamps of the
strain-relief device, depending on the cable routing.
