18 OMEGA Installation, Operation, and Maintenance Manual
IMPORTANT: Be sure the nut is aligned with the top of the
OMEGA enclosure. If the nut is not parallel to
the top of the enclosure, the OMEGA top cover
will not close completely.
Connecting the Input Voltage Source
The following procedure describes how to connect OMEGA to an
input voltage source of 90 - 277 VAC. When making this
connection, use a UL-listed and approved power cord with a rating
of 10 amps or above.
The OMEGA enclosure is pre-drilled with a hole that is .875
inches in diameter. This hole is used to accommodate a standard
AC power cord and the conduit for the power cable running
between the power source and the OMEGA unit.
1.
Lift the AC fuse connector to turn off AC power to OMEGA
(see Figure 1-1 on page 13). Do not close this AC fuse
connector when connecting the input voltage source.
2.
Insert the power cord through the conduit hole at the bottom of
the compartment (see Figure 1-3).
