CAUTION
1 KB (Battery Kit) represents a string of 20 batteries in series.
In case of models with internal battery drawers and for external modular battery units, 1 KB comprises 4 battery drawers.
It is necessary to install 1 KB every 10 kVA of nominal UPS power in case of modular units with battery drawers.
For example , for the Trimod HE 40 it is necessary to have at least one external modular battery unit with 4 KB (16 battery
drawers).
In case of non-modular 94Ah external battery units, each unit represents 1 KB and 1 KB is sufficient for all the Trimod HE
models.
Connection of one external modular battery unit to the Trimod HE 10-15-20-30TT/TM
The Trimod HE MODULAR BATTERY 4KB-5KB must be connected to the Trimod HE 10, 15, 20 and 30 TT-TM with one of
the multipolar cables provided with each battery cabinet.
CAUTION
Table 8 of chapter 11 includes instructions for sizing the cables to connect the UPS to the external battery unit in case the
multipolar cable provided is not used.
The maximum length of the connection cable between the UPS and the battery unit must not exceed 3 meters.
In case of configurations where there are more than one external battery units, it is recommended to implement a battery
switchboard as indicated in this paragraph under the subtitle “Connection of two or more external modular battery units
to the Trimod HE”.
The connection must be made according to the diagram and the passages indicated below:
1. Check that all the battery fuse disconnectors are open.
2. Loosen the screws that keep close the panel that gives access to the terminal strips of the external battery units.
3. By using one of the multipolar cables provided with the external battery unit, connect the UPS to the external battery
unit installed using the earthing wire (yellow-green).
4. By means of the multpolar cable used in the preceding point , connect the positive and negative terminals of the UPS
with those of the external battery unit installed.
5. Refit the panel and tighten the screws.
