2 Quick installation instructions
Please do all steps following the numbers below. Do not go ahead if any step failed.
1. Check system parameters and PowerTarom label : System voltage, max. module/load current
2. The solar modules have to be equipped with an extra switch or circuit breaker (CB).
3. fix the PowerTarom vertically at the wall
4. Switch off battery, modules and load:
a. switch off external battery fuse or CB and the main CB inside the PowerTarom
b. switch off the modules at the external module CB
c. switch off all loads
5. cabling (not yet to be switched on)
a. connect the battery poles to the A+ and A (blue) terminals. Respect polarity!
b. connect the modules to the M+ and M (blue) terminals. Respect polarity!
c. connect the load to the L+ and L (blue) terminals. Respect polarity!
6. switch on battery
a. switch on battery CB (external and in the PowerTarom). Do not switch on the modules yet.
b. watch the LC-display for proper indication of system voltage
7. switch on the modules
a. switch on the external module CB
b. watch the LC-display for proper indication: during daylight you should see the module currents,
