9.1 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.
– Do not open the controller case.
– All covers must be installed during operation.
– Always take the following measures before working on the controller:
1. Switch off all loads.
2. If present, 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, solar module and loads to the controller in the
described sequence.
– Secure the connected cables with a strain relief clamp, see Quick Guide section 6. Clearance
of strain-relief to controller: 200 mm.
– Connect only 1 cable to each connection terminal.
– Cables used: Observe the specifications in the Technical data section.
– 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 (line fuse or DC line circuit breaker) is mandatory.
Observe the following:
– Mount the external battery fuse directly next to the battery.
– The external battery fuse must conform to the specifications in the technical data section.
– The external battery fuse is not included in the scope of delivery.
