Special Considerations—Generators and
Backup Power Systems
On site power generation and backup power systems
create special considerations both because of the pow-
er quality itself and also the manner in which the load is
transferred between mains and backup (and reversion
to mains). If this installation will incorporate either on –
site generation or some other form of back up power,
please consult AMETEK Engineering for a review of the
planned system prior to implementation. AMETEK En-
gineering will review the system specifications and
make a determination as to whether any changes
would be required in order to provide coverage under
the standard warranty.
Charging Cable Connectors
If connectors are already attached to charging cables,
make sure that they are attached so that positive
charger polarity will connect to positive battery terminal.
If connectors must be attached to charging cables,
follow instructions supplied with connectors.
Consider the connectors auxiliary wiring when inspect-
ing it as these CAN chargers are designed to use those
wires to communicate to the BMS of the Lithium bat-
tery.
CAUTION: Make sure connectors are
securely attached to cables (good
solder joint or well tightened set screws,
whichever is applicable). Be certain
that positive charger cable will connect
to positive battery terminal. If necessary,
trace cables into charger to determine
polarity. The use of a DC voltmeter may
show polarity. Improper connections
will "blow" output fuse and may cause
other damage.
Pre-operation Checks
1. Inspect charger thoroughly for damage; loose
screws, nuts, or electrical connections.
WARNING: ELECTRICAL SHOCK
HAZARD – Before inspecting or
cleaning inside cabinet, turn OFF
and remove fuses of disconnect
switch (supplying AC power to
charger) and disconnect battery.

2. Remove all special tags that are tied to charger.
Keep tags with this manual for future reference.
Leave all precautionary and instruction labels in
place on charger. Carefully read and follow
instructions on all tags and labels. Make sure all
labels remain visible to anyone operating charger.
3. Make sure all charger cabinet panels are fastened
in place, to assure proper flow of ventilating air
through cabinet.
Pre-Operation Changes To The Factory
Control Settings
Typically few changes are required to be made if the
amp hour rating is sized to the battery and the voltage
rating is equal to or greater than the battery. However,
in some applications, some changes to the
programmable control settings may be desirable. The
most common changes are listed below:
TIME
Factory Setting for Time is Eastern
Standard. (see Programming the
EC2000).
NO GASSING HOURS
Factory Setting is 0 (see Programming
the EC2000).
MAX BATTERY TEMPERATURE
Factory Setting is 150° F (see Pro
gramming the EC2000).
NOTE: It is advisable to check the day of the
week, date, month, and year for accuracy
AUTO EQUALIZE
Factory setting is ON (see Program
ming the EC2000).
AUTO EQUALIZE TYPE
Factory setting is by Cycle (see Pro
gramming the EC2000).
AUTO EQUALIZE COUNT
Factory setting is 05 (see Program
ming the EC2000).
The chargers START MODE will be AUTO by default
and this will charge a BMS lithium battery as well as
any battery without a BMS. The start mode can be
charged to BMS to only charge a lithium battery with a
BMS.
