for a procedure.
DC Power Supplies
One or two power supply modules can be installed. If only one module is being
installed, it can be installed in either power supply slot (PSA or PSB).
However, the remaining slot must be covered with a filler plate. The filler plate
is necessary for safety and ensures proper airflow within the chassis. By
default, the chassis has the filler plate installed over PSB on the right.
For installations using 24 V or 36 V input voltage, the recommended fuse
value is a minimum of 5 Amps. For systems using 48 V input voltage, the
recommended fuse value is a minimum of 2.5 Amps.
The DC power cord should be 14 AWG - 18 AWG wire. You will need to install
fork terminal spade lugs on the power cord to ensure a proper connection with
the terminal block of the power supply.
contains a
summary of the recommended locking fork terminal lugs.
WARNING:
The DC version relies on the connector at the front of the power supply
to provide Safety Ground. This grounding connection must be properly attached
when the 3930 is installed.
WARNING:
A readily accessible disconnect device shall be incorporated
external to the equipment.
