CAUTION
Air enters through the bottom/side cold-air intake of the enclosure and exhausts at the top hot-air
exhaust end of the enclosure. Blocking these openings will cause overheating and unit failure.
CAUTION
Do not apply more than the rated Voltage or exceed the power rating of the Load Bank. Excessive
power will damage the internal resistor banks.
CAUTION
Confirm all control voltages before operation. Improper Voltage or Over-Voltage will damage load
resistors, fan motors, and control components.
CAUTION
Confirm that all load, control, and blower connections are securely attached, turned, and tightened,
and that the unit is properly grounded prior to operation. Failure to do so may result in equipment
damage and harm to personnel.
CAUTION
Not using all four (4) mounting holes when anchoring the enclosure will lessen wind load and
mechanical integrity of the unit and may result in equipment damage, property damage, and/or harm
to personnel.
Inspection and Unpacking
As part of your safety program, an initial inspection of all equipment should occur after receiving the
unit. Periodic preventative maintenance and inspections should be performed to ensure system
reliability. Upon receipt of your Load Bank, be sure to carefully unpack the unit and inspect the unit
carefully for any shipping damage. Check for loose, broken or otherwise damaged parts due to
shipping. If damage is noticed, do not unpack the unit. Immediately notify ULB and report any shipping
damage to the freight carrier. Be sure to verify that the part number and ratings listed on the
nameplate match the order specification.
The ratings listed on the nameplate are critical –
installing, operating, and energizing the incorrect part number could damage the unit and load
resistors.
If the unit is not damaged, unpack the equipment and remove protective stretch wrap. Remove all
covers and inspect all of the components for visual signs of damage. Immediately notify the freight
carrier and ULB of equipment damage or missing parts. Reinstall packing materials for storage with
exception of stretch wrap.
Do not store the unit with the protective plastic in place.
NOTE: Do not reinstall or reapply protective stretch wrap. This material is meant for shipping
protection only. Prolonged storage in stretch wrap may cause condensation damage to powder coat,
painted, or mill galvanized finishes.
Product Overview
TLB-R1000-480-OS Series of Stationary Outdoor Resistive Load Banks are designed for installation
and operations outdoors – typically mounted and secured on a roof or to a concrete pad. The Load
Bank is an industrial power test unit specifically designed for outdoor operation, and will absorb a
balanced resistive load at unity power factor. The Load Bank is a self-contained unit that includes a
Remote Operator Control Panel which allows the user to control and monitor individual-discrete load
