Connection of two external modular battery units to the Trimod HE 60
A Trimod HE 60 can only be connected to two TRIMOD HE MODULAR BATTERY 5 KB (20 battery drawers) using exclusively
external cables as per the instructions provided in table 8 of chapter 11.
The multipolar cables provided with each battery cabinet must only be used for the cascade connection of the first
external battery unit to the second.
CAUTION
The maximum length of the connection cable between the UPS and the first battery unit must not exceed 3 meters.
It is not possible to connect only one TRIMOD HE BATTERY 5KB to the Trimod HE 60.
The external battery units must be homogeneous in the number of battery drawers. The difference between one
unit and the other must be a maximum of 1 KB (4 battery drawers).
In case of configurations where there are two or more 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 cascade connection of the two external battery units 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. Connect the UPS and the first external battery unit installed using an earthing (green/yellow) cable
4. By means of two cables with minimum cross-section indicated in table 8 of chapter 11, connect the positive and
negative terminals of the UPS with those of the first external battery unit installed.
5. Connect the first battery unit installed with the second using both the multipolar cables provided by connecting the
earthing cable first and then the positive and negative terminals.
6. Close the panel and tighten the screws.
