4.1 Safety instructions
DANGER!
Risk of death by electrocution! Observe the following safety instructions when performing the
measures described in the installation section.
General information
– Only technical professionals may perform the work described in the 'installation' section.
– The PE connection must be connected to the system ground (grounding spike).
– If the system is to be positively grounded then PE must be
additionally connected to bat-
tery terminal
B+
. The external battery fuse must then be installed in the
B–
cable!
– In this case, the system must not be negatively grounded.
– The solar module installation branch, including the DC load circuit breaker up to the controller
terminal area, must be implemented to protection class II.
– The battery installation branch must be implemented to protection class II.
– The following components must be installed:
–
Battery
– At least 1 solar module
– External battery fuse (fuse or DC circuit breaker)
– DC load circuit breaker for solar module 1 and 2
– Do not open the controller case. Only the terminal cover may be removed by a technical pro-
fessional for installation.
– Always take the following measures before working on the controller:
1. Switch off all loads.
2. Switch off the DC load circuit breaker (solar module) and secure it against being switched
on again or safely cover the solar module (wind).
3. Switch off the external battery fuse: Remove the fuse insert from the fuse holder (safety
fuse) or switch off the DC line circuit breaker and secure it against being switched on again.
4. Disconnect the battery cable from both battery terminals.
Cable connections
– The module cables carry voltage when the solar module is illuminated.
– Insulate exposed cable ends with insulation tape or wire connector blocks.
– Connect the cables for the battery and solar module to the controller in the described
sequence.
– Secure the cables with a strain relief clamp. Clearance of strain-relief to controller: 200 mm.
– Connect only 1 cable to each connection terminal.
– Lay the cables so that
–
connections cannot accidentally come loose,
– persons cannot tread on or trip over these,
– fire protection devices must not be impaired.
– The entire installation must be designed with Protection Class II if the open-circuit module
voltage exceeds 60 V DC at least once anywhere over the entire temperature range.
– Observe all applicable installation regulations and standards, national laws and connection
values specified by the regional power supply company.
Fuses and switching devices
Installation of an external battery fuse (fuse or DC line circuit breaker) is mandatory. Observe the
following:
