When sizing the battery system, do not exceed the internal battery charger capabilities. See Chapter 10,
“Product Specifications,” for maximum battery charger currents.
MISE EN GARDE!
Lors de l’évaluation du système de batterie, ne pas dépasser les capacités internes du chargeur de batteries.
Se reporter au chapitre 10 sur les notices techniques pour connaître les tensions maximales du chargeur de
batteries.
To install wiring to connections:
NOTE
Battery Cable Routing Requirements using Conduit:
* Each conduit must have a Positive, Negative, and Ground conductor
.
* There must be an equal number of positive and negative conductors in a single conduit. Only
. one ground conductor is required in each conduit.
Battery Cable Routing Requirements using Raceway:
* Positive and negative battery cables must be run side by side in the raceway in an alternating
pattern (+ - + - + - + -).
* There must be a ground cable running in the raceway with the battery cables.
1.
Route the battery cables between the ISBM section and the battery system or
battery disconnect. See Figure 4‐5 through Figure 4‐8 for wiring access
information and terminal locations.
2.
3.
Using hardware from the external wiring terminal hardware kit (see Table 3‐8),
connect the positive, negative, and ground DC power wiring from the battery
system or disconnect to the ISBM section battery and ground terminals. Use
both sets of terminals shown in Figure 4‐8 as needed. See paragraph 3.2.3 for
wiring and termination requirements.
4.
5.
Using hardware from the external wiring terminal hardware kit (see Table 3‐8),
connect the positive, negative, and ground DC power wiring from the battery
systems or disconnects to the ISBM section battery and ground terminals. Use
one set of terminals for each UPM. See paragraph 3.2.3 for wiring and
termination requirements.
6.
After wiring the UPS system to the facility power and critical load, be sure to
ground the system according to local and/or national electrical wiring codes.
7.
If wiring interface connections, proceed to paragraph 4.7; otherwise, proceed to
Step 8.
8.
When all wiring is complete, reinstall the top and bottom safety shield panels
removed in paragraph 4.6.2, Step 2. Secure with the retained hardware.
9.
Reinstall the left front panel removed in paragraph 4.6.2, Step 1 and secure with
the retained hardware.
