4.3. Load
Power to the loads is supplied via the external Power Point or
by hardwired connection. If hardwiring, simply attach the Active,
neutral and earth to the terminals blocks labelled “Loads” on the
inside of the unit. Alternatively, plug in a device to the GPO
labelled Power Output.
Note that this output is limited to 15 Amps (approximately 3kW).
4.4. Generator Connection
Power to the BlackMax can be supplied via the external power
inlet or hardwire connection.
If connecting the generator via power inlet, simply attach the
device to the power inlet labelled “GENERATOR INPUT”.
NOTE: A 15A rated cable must be used for this input.
The following specifications must also be met for a guaranteed
compatibility with the inverter.
-
Generator waveform THD: < 10%.
-
Generator Vrms range: 180 ~ 264Vac
-
Generator voltage crest factor (Vpeak/Vrms): < 1.6
-
Generator peak voltage: <380V
-
Frequency range: 45Hz ~ 55Hz
-
Frequency slew rate: <0.3Hz/sec
To hardwire the generator, the leads from the Gen inlet must be
removed from the terminal block and terminated. Then secure
the active neutral and earth to the terminal blocks.
NOTE: If the system is hardwired, there are stickers in the parts
kit to be placed on the power inlet lead as well as the power inlet.
4.5. Generator Auto-Start
BlackMax contains three terminals (NO, C and NC) on the bottom of the display. These terminals
are connected to a dry contact that can be programmed to automatically start a generator, or it can
be used to activate a signal light indicating that the manual start generator is required. To learn how
to configure this relay, please refer to the SurePower Manual
Tip: When using an AutoStart generator, install a small battery charger on the generators battery
so it does not discharge over time.
