NEMA Adapter Connection (Optional -
PDUMH20HV Only):
The PDUMH20HV includes a
plug adapter that adds a NEMA L6-20P plug to the
input power cord. Use this adapter only if you will
be connecting the PDUMH20HV to a NEMA L6-20R
outlet. Insert the IEC 60320 C19 connector
A
of
the adapter into the IEC 60320 C20 connector
B
of the input power cord. Secure the connection
with the retention bracket
C
by using the included
bolts to fasten the two halves of the bracket around
the connection as shown.
Caution: To avoid the risk of electric shock,
ensure that the Neutral (L2) conductor has
been identified before connecting the PDU.

Input Power Cord Connection (PDUMH20HV
Only):
Insert the IEC 60320 C19 connector
A
of
the input power cord into the IEC 60320 C20 inlet
B
of the PDU. Connect the other end of the input
power cord
C
to a compatible source of AC power,
such as a UPS system, PDU or utility outlet. The
PDU should be provided with over-current
protection. PDUMH20HV should be provided with a
maximum 20A branch-rated over-current protection
device.
Note:
The AC power source should not share a circuit with
a heavy electrical load (such as an air conditioner or
refrigerator).

Attach equipment to the PDU.
Do not exceed the
load rating of the PDU. The total electrical current
used by the PDU will be displayed on the digital
meter in amperes.
