to 95%, non-condensing.
•The transformer should be installed in an environment with an altitude of 1000 meters
(3,281ft.) or lower with no derating.
•The transformer internal cooling is dependent on the system fan, so it should be kept in
a good air ventilated area.
Equipment Connection
•The power input on the transformer must be connect only to a circuit provided with
branch circuit overcurrent protection in accordance with the National Electrical Code,
ANSI/NFPA 70 and the Canadian Electrical Code, Part I, C22.1.

•Only use the input cable supplied with the transformer.
•Input power is restricted to 208 VAC.
•WARNING: Do not use 240 VAC to power the transformer.
•Connect the transformer only to an earth-grounded outlet that is easily accessible and
near the transformer unit.
•Attach protective grounding wire to the grounding screw located on the transformer
rear panel. The recommended grounding-wire gauge is 10 mm2
•Do not connect appliances or devices that would overload the transformer according to
the rated load capacity.
•Use only UL, VDE, CE certified power cables to connect the loads to the transformer.
Maintenance Information
•The transformer contains no user-serviceable internal components and does not require
routine maintenance.
•For other performance issues see Appendix A: Troubleshooting.

Step-Down Transformer Physical Features and Accessories
The following sections provide an overview of physical features on the Step-Down
Transformer unit.
Physical Features
Step-Down Transformer Front Panel
The Step-Down Transformer front panel is a 2 RU form factor designed to conform with
the Panduit 5-10 KVA UPS product line. The front panel contains air flow vents and a
moniker denoting the identity of the unit. The molded faceplate is removeable via push-
in tabs on the sides.

UPS STEP-DOWN TRANSFORMER USER MANUAL

Figure 11: Step-Down Transformer Front Panel
Air Flow Vents
The air flow vents are critical to the operation of the Step-Down Transformer unit. These
vents must remain clean and clear of all objects that may restrict the air flow through the
unit.
Step-Down Transformer Rear Panel
The rear panel of the Step-Down Transformer contains the NEMA L6-30P input plug,
120 V NEMA 5-20R outlets, a NEMA L6-30R pass-through outlet, breaker reset
switches for the 120 V outlets, and a toggle 25A / thermal input breaker.
Input Power Cord (INPUT)
The Step-Down transformer input cord is equipped with a NEMA L6-30P 208 VAC 30A
plug with a length of 0.6 meters.
WARNING: Do not power the Transformer unit with 240 VAC.
Input Breaker
The Step-Down transformer input cord is equipped with an input breaker rated at 25A.
The input breaker has a manual reset switch. Outlet groups will be disabled when this
switch is opened. The input breaker is closed (ON) when the indicator on the breaker is
orange and opened (OFF) when the indicator is green. There are additional markings
on the rear panel to denote the ON and OFF positions.
Chassis Ground Connection Point ( )
The Step-Down Transformer rear panel contains a chassis ground connection, labeled
with a ground symbol. For safety and proper grounding procedures, this grounding
connection point must be connected to the rack/cabinet ground.
Output Receptacles (denoted as GROUP1, GROUP2, GROUP3, GROUP4)
The Step-Down Transformer has four groups of 120 VAC NEMA 5-20R power output
connectors, labeled: GROUP 1, GROUP 2, GROUP 3, and GROUP 4. Each of these

UPS STEP-DOWN TRANSFORMER USER MANUAL
11
outlet groups contains three outlets and are protected by a 20A breaker. The breaker is
resettable via a manual push button.
Outlet GROUP 1 and GROUP 2 are paired and may share up to 3000 VA load (1500
VA each). Outlet GROUP 3 and GROUP 4 are paired and may share up to a 3000 VA
load (1500 VA each). The Step-Down Transformer also contains a pass-through 208 V
NEMA L6-30R outlet group, labeled GROUP 5. Total rated capacity of the Transformer
is 5000 VA distributed between these outlet groups.
Cooling Fan
The transformer is equipped with a cooling fan that will run when the unit is powered up.
The fan is critical in preventing the transformer coil from overheating, which may cause
damage to the equipment.
WARNING: Do not use the transformer if the fan is blocked or has malfunctioned.

Appendix A: Troubleshooting
If the transformer is not properly functioning, it may be related to improper installation,
wiring, or operation. Follow the troubleshooting procedures below as a first pass
analysis of the problem.
No.
Problem
Possible reason
Solution
1
The mains source is
connected but the
transformer will not
power ON. (No voltage
at the output.)
Input power source is not
providing power.
Input voltage and/or
frequency is too low or too
high.
The input breaker of the
transformer is not turned
ON.
Use a multimeter to measure the source
voltage and frequency connected to the
transformer input to ensure it is within
the operational input range.
Check that the transformer input breaker
is turned ON.
2
The source is
connected and powered
but the fan is not
functional.
Input voltage is insufficient.
The fan may have jammed
or malfunctioned.
Verify input voltage is within nominal
range.
Power off unit and clear obstructions if
possible.
If fan has malfunctioned, do not use
transformer and contact customer
support for repair or replacement
options.
3
The output breaker
does not reset once
tripped.
The output breaker may
have malfunctioned.
Disable power to the transformer. Let
the unit cool if hot. Reset the output
breaker. Power the transformer back on
and power is present at the outlets.
If problem persists, contact Panduit
customer support for repair or
replacement options.
4
The input breaker has
tripped.
The transformer may be
overloaded.
The transformer coil has
overheated.
Reduce the load on the transformer
outlets. Verify that the fan is running and
there is nothing obstructing the front and
rear ventilation. Let the unit cool down.
Manually switch the input breaker switch
back on.
