Safety 4 - 3
Safety Statements, continued
•
Torque electrical connections to the values specified on labels or in
the product documentation.
•
Battery input cables must be dressed to avoid damage to the
conductors (caused by routing around sharp edges or routing in
areas where wires could get pinched) and undue stress on the
connectors.
•
Alarm contacts on the distribution panel (J6 on left side of shelf and
J2 on ES610, ES611, and ES613) are not fused within the
distribution panel; therefore, current limiting protection for these
contacts must be provided by external circuits. Maximum ratings
for alarm connections are 60Vdc and 0.5 amperes. Exceeding these
maximum ratings could result in fire or damage to the unit.
•
Fuse and/or circuit breaker loads must not exceed 80% of the fuse
and/or circuit breaker current rating. Distribute loads across the
panel.
•
The short circuit current capability of the battery input to the
distribution panel must not exceed 9000A.
•
AC branch circuits to this equipment must be protected with either
fuses or circuit breakers sized as required by the National Electric
Code (NEC) and/or local codes. The maximum size of the
over-current protector is recommended to be no more than 30A.
Refer to the equipment ratings to assure rating of equipment will
not exceed 80% of the value of the protector chosen.
•
An accessible ac disconnect/protection device to remove ac power
from the equipment in the event of an emergency must be provided.
•
High leakage currents are possible. Earth ground connection is
essential before connecting the ac source to the shelf.
