Chapter 1: Introduction
Thank you for purchasing this power protection product. It has been designed
and manufactured to provide many years of trouble free service. Please read
this manual before installing your Endeavor Series step down transformer
(ED-XFR), models ED5000RT-XFR, ED6000RT-XFR, ED8000RT-XFR and
ED10000RT-XFR as it provides important information that should be followed
during installation and maintenance of the ED-XFR allowing you to correctly
set up your system for the maximum safety and performance. Included is
information on customer support and factory service if it is required. If you
experience a problem with the ED-XFR please refer to Obtaining Service section in this manual to collect enough information so that the T echnical Support
Department can rapidly assist you.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS !
CAUTION! This ED-XFR series is ONLY intended to be installed in an indoor
temperature controlled environment that is free of conductive contaminants.
This ED-XFR series is not intended for use in a computer room as defined in
the Standard for the Protection of Electronic Computer/Dat a Processing Equipment ANSI/NFPA 75. The AC inputs of these Step Down Transformers are
ONLY intended to be connected to the output of their respective UPS models.
The ED-XFR's input voltage setting must be the same as the UPS's output voltage
setting.
CAUTION! The maximum ambient operating temperature for this ED-XFR
series is 40°C (“0 ~ 40°C” for Ambient Operation).
The external vents and openings on the unit are provided for ventilation.
T o ensure reliable operation of the unit and to protect the unit from overheating, these vents and openings must not be blocked or covered. Do not
insert any object into any of the vents or openings that may hinder the ventilation.
Install the unit in a well ventilated area, away from excess moisture, heat,
dust, flammable gas or explosives.
Leave adequate space (at least 15cm) around all sides of the unit for pr-
oper ventilation.
Do not mount the unit with its front or rear panel facing down at any angle.
Before usage, you must allow the unit to adjust to room temperature
(20°C~25°C or 68°F~77°F) for at least one hour to avoid moisture cond ensing inside the unit.
CAUTION! The ED5000RT-XFR and ED6000R T-XFR come with an attached
#10 AWG input power cord. Connect the input power cord to the output
terminal block on the UPS. The AC input s of these Step Down Transformers
are ONLY intended to be connected to the output of their respective UPS
models. Do not use extension cords, adapter plugs, or surge strips. The
installation of upstream and downstream protective devices is highly recommended when the UPS system is connected to the mains and the load.
CAUTION! The ED8000RT -XFR and ED10000RT-XFR come with an #6 A WG
input power cable in the box. The pins for the input and output cables are
included. Connect one end of the input power cable to the input terminal block
on the ED-XFR. Connect the other end of the input power cable to the output
terminal block on the UPS. The AC inputs of these Step Down T ransformers
are ONLY intended to be connected to the output of their respective UPS
models. Do not use extension cords, adapter plugs, or surge strips. The
installation of upstream and downstream protective devices is highly recommended when the UPS system is connected to the mains and the load.
CAUTION! To reduce the risk of electrical shock with the installation of this
unit and the connected equipment, the user must ensure that the ED-XFR is
properly grounded due to a possible risk of AC current leakage.
WARNING: Qualified Service Personnel ONLY must perform the Installation and Servicing of these ED-XFR. MINUTEMAN accepts no liabilities and is
not limited to: injury to the Service Personnel, or damages to; the Step Down
Transformer , the UPS, the Battery Pack, or the connected equipment caused
by the incorrect installation or servicing of the UPS system. These ED-XFR
MUST be operated with their respective UPS models, see the table below:
