IMPORTANT SAFETY INSTRUCTIONS ARE CONTAINED IN THIS MANUAL
To reduce the risk of electrical shock and to ensure the safe operation of the MP2000E, the
important safety instructions are marked with the symbols shown below. These symbols are
used throughout this manual to indicate that the instructions being presented are for
procedures that should only be carried out by qualified personnel.
Indicates presence of DANGEROUS VOLTAGE. Extreme caution
should be used.
Calls ATTENTION to important instructions. Follow them as indicated.
DANGER: Do not expose the MP2000E to rain or moisture.
DANGER: Total earth ground leakage current of loads connected to the MP2000E
should not exceed 2.4 mA.
The MP2000E generates, uses, and can radiate radio frequencies if not installed
and tested in accordance with the instructions contained in this manual. It has
been tested and found to comply with the limits established for a Class A
computing device pursuant to part 15 of FCC rules, when it is operated alone. It
also complies with the radio interference regulations of DOC, which are designed
to provide a reasonable protection against such interference, when this type of
equipment is used in a commercial environment. If there is interference to radio or
TV reception, which can be confirmed through switching the MP2000E on and off,
relocate the radio or TV equipment or use an electrical circuit other than the one
used by the MP2000E.

IMPORTANT SAFETY PRECAUTIONS
ONLY QUALIFIED PERSONNEL SHOULD SERVICE OR SUPERVISE THE SERVICE OF THE MP2000E.
DANGER: The MP2000E uses sealed lead-acid batteries with high energy and chemical hazard
levels. This manual contains important operation and safety instructions.
MP2000E SYSTEM SAFETY CHECKLIST

Unpack the MP2000E carefully. Report any shipping damage at once.
Read this manual. If you have any questions about safe installation, operations, or
maintenance of the system, contact the Myers Emergency Power Systems service
department at 610-868-5400.
Before installation, confirm that the voltage and current requirements of the load(s) is /
are compatible with the system’s output. Confirm that the line voltage and current are
compatible with the system’s input requirements.
Install the MP2000E on a dedicated power circuit.
Place a warning label on the enclosure indicating that a Battery Back-Up (BBS) is
located inside.
Use proper lifting techniques when moving the system.
Be advised that the MP2000E has more than one live circuit. It is fed from AC as well as
battery power. Power may be present at the output(s) even if the system is
disconnected from line power.
When installing a system in other than a Myers Emergency Power Systems cabinet,
verify that the environment meets the system specifications as presented in Section 3
of this manual.
SAVE THIS MANUAL
It contains important installation and operating instructions.
Keep it in a safe place.

BATTERY SAFETY CHECKLIST

High & dangerous voltages are present inside the system. Only qualified personnel
should perform installation and maintenance.
Live battery wires must not touch the MP2000E chassis or any other metal objects. This
can cause a fire or explosion.
Inspect the batteries once a year for signs of cracks, leaks, or swelling. Replace as
needed.
When batteries are in storage, charge them at least once every three months for
optimal performance and to extend their lifetime.
Always replace batteries with the ones of identical type and rating. Never install old or
untested batteries. Never mix old batteries with new. Never mix the different amp hour
rated batteries within one system.
Use insulated tools during servicing.
Remove all rings, watches, jewelry, or other conductive items before working inside
Follow local regulations for the disposal of batteries. Recycling is the best method.
Never burn batteries to dispose of them. Doing so may cause them to explode.
Do not open the batteries. The contents are toxic.

STANDBY GENERATOR CHECKLIST

Note: If the MP2000E constantly switches between Battery and Line modes because
of line fluctuations, the input parameters should be broadened from Normal to
Generator (see Section 6.b.2.1 “Sense Type”)
In Generator mode, the acceptable range of input frequency and voltage is expanded to
accommodate the voltage and frequency fluctuations created by a generator or a power
source of such kind.
Use a generator with electronic speed and voltage controls which typically produces
the Total Harmonic Distortion in % (THD) to be less than 10%. Generators with
mechanical governors can force the system to run continuously in Battery mode.
Before installation, compare the generator’s output voltage to the MP2000E’s input
voltage requirements as listed on both nameplates. To ensure the system’s smooth
operation, use a generator capable of supplying 200% or twice as much power as
required by the total load.

UNPACKING &INSPECTION CHECKLIST

Carefully remove the MP2000E from the box and inspect the contents.
Verify that the box contains 1 MP2000E BBS System.
Verify that the box contains 1 temperature sensor probe cable with three-pin connector
Verify that the box contains 1 Operating Manual
Verify that the box contains 1 binder of Electrical/Mechanical Drawings
The Power Transfer Switch (PTS) and all the associated wiring & hardware required for
installation are supplied in a separate box.
The set of four (4) batteries may be shipped separately, if a large quantity of MP Series
systems is supplied.
SAVE THE ORIGINAL SHIPPING MATERIALS
When returning the MP2000E for servicing, use the original shipping box and Styrofoam
protectors. Myers Emergency Power Systems is not responsible for damage caused by
improper packaging of returned systems.
READ THE OPERATING MANUAL
Before installation, become familiar with the MP2000E by reviewing the procedures and
drawings in this manual. If you have any questions about safe installation, operation, or
maintenance, contact Myers Emergency Power Systems service department at 866-MY-
MYERS.
NOTE
If any items are missing or damaged, contact Myers Emergency Power
Systems (610-868-3500) and the shipping company immediately.
Most shippers have a short claim period.
