CAUTION
•
Leave breakers turned off until the software has been
configured (see Section 3.2.4 or Section 4.6.2).
•
DC-AC Inverters should not be connected to the outputs of
the Load Distribution Module of a power system. DC-AC
Inverters create significant inrush current and may damage
the circuitry or interfere with the operation of power supplies
that they are connected to. Connecting an inverter in this
way may void the product warranty. ICT recommends
connecting a DC-AC inverter to the battery bank.
1.
Locate the four controlled outputs on the LDM rear panel connector
block.
NOTE: The internal channel relay, current sensor and circuit breaker are in
the "hot" or output line, with voltage polarity depending on the
configuration of the unit (each output = NEG V, for −48 V configured
systems, each output = POS V, for +24, or +48 V configured
systems).
2.
Ensure that the breakers on the LDM are turned off until the
software has been configured (see Section 3.2.4 or Section 4.6.2).
3.
Verify the polarity of the Hybrid Ultra.
4.
Connect up to four external loads using appropriately rated wire
inserted and secured into the four cage-clamp output connector
pairs on the LDM module rear panel. The LDM will accept wires
from 12–22 AWG.
The integrated isolated DC-DC Converter Module output has "POS" and
"NEG" terminals. Ensure polarity is correct when connecting the load. Do
not connect the loads to the DC-DC Converter Module output bus bars until
the software has been configured (see Section 3.2.3 or Section 4.4.2).
