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.
