Cascading Power
When installing multiple IE-Giga-MiniMc units on a DIN rail, connect to one DC
input source and then cascade from one DC block to the next, until reaching the
maximum electrical current available.

DC Power Supply Precautions
The following precautions should be observed when installing chassis with DC power
supplies.
1.
Check nameplate ratings to assure there is no overloading of supply circuits that
could have an effect on overcurrent protection and supply wiring.
2.
When installing 7 to 50 rated equipment, it must be installed only per the
following conditions:
a.
Connect the equipment to a 7 to 50VDC supply source that is electrically
isolated form the alternating current source. The 7 to 50 VDC source must
be connected to a 7 to 50 VDC SELV source.
b.
The maximum terminal voltage is 50 VDC.
c.
Input wiring to terminal block must be routed and secured in such a
manner that it is protected from damage and stress. Do not route wiring
past sharp edges or moving parts.
d. A readily accessible disconnect device, with a 3mm minimum contact gap,
shall be incorporated in the fixed wiring.
3.
Grounding: reliable grounding of this equipment must be maintained. Particular
attention should be given to supply connections when connecting to power
strips, rather than direct connections to the branch circuit. The Negative
Terminal is common to the grounded case.
