3.1 Startup
Switch all breakers on the PDU control panel to the off position. Switch the
Outlet Control Bus
mode switch to the up
position labeled
Local/On
. (This forces the PDU into local mode, ignoring any existing remote panel for now.)
Insert the PDU’s inlet connector into the facility mains power source. If there is a facility power disconnect, switch that to
the On position. At this point, the PDU is energized, though all indicator lamps will be off.
Switch the PDU’s
Main Breaker
to the On position, and the
Φ
A,
Φ
B,
Φ
C indicators will be lit. All branch circuits are ready
for use. As each branch breaker is switched on (e.g.
CB1
,
CB2
, etc.), the indicator above it will be lit.
If there is not an EPO panel connected to the PDU, leave the switch in the up
Local/On
position. If there is remote EPO
panel connected to the PDU, such as Marway’s Commander UCP 5000, flip the
Outlet Control Bus
switch to the down
Remote
position.
3.2 Breaker Controls
The PDU has three distinct groups of controls: the main breaker, the branch breakers, and the remote EPO system.
3.2.1 Main Breaker
The
Main Breaker
prevents or enables power to all PDU outlets. When
Main Breaker
is switched on, the indicators
labeled
Φ
A,
Φ
B,
Φ
C will be lit.
This breaker includes a breaker guard with a lockout feature. Attaching a small padlock (not included) through the guard
hole will prevent the breaker from being switched on.
3.2.2 Branch Breakers
All Optima 533 models include eight branch breakers. All are rated at 16 A continuous load (20 A maximum). CB1 is for J1
(both outlets of the duplex). CB2 is for J2, et cetera. There is no breaker for the L21-30 outlet J9 on the models where this
outlet is included. Each breaker has an unlabeled, corresponding indicator just above it. When the breaker is in the on
position, the corresponding lamp will be lit.
