Installation
The cabinet in which the battery will be installed must be in closed electrical enclosure
according to chapter 5.2.7 of EN50178-1:1999 standard.
If the product is brought to the installation location from a cold environment, condensation may
form and this may lead to damage the electronic equipment. Before commissioning, the product
must be dry. Wait 2 hours after transportation before installing the product.
3.4. Assembly
installation
The modules must be stacked horizontally. They must be protect against external aggression
(shock, piercing, short-
circuit, water, falling of objects, pollution dust,…).
If the battery is not installed inside a closed cabinet, no flammable material must be stored near
the battery (2 meters radius).
3.5. Battery start-up
The start-up is done by supplying the BMM with 24VDC. The BMM immediately proceeds to its
self-test by testing its internal functions.
During self-test, the battery will be connected. Beware of high voltage
.
The battery communicates by CAN-Open protocol. At start-up, the CAN-Open node is in
Pre-
operational State
: the BMM waits for a
Start_Remote_Node
frame (with CAN-Open NMT
service) to go to
Operational State
. After that, the BMM is operational and sends continuously
messages on CAN Open bus.
Then the EMS must authorize the contactor closing by sending a command by CAN (CAN
Open Object 2055 on RPDO2): at this stage, EMS can use the battery properly.
3.6. Battery shutdown
To shut-down the battery, disconnect the 24VDC supply voltage (battery contactor opens within
5s and the connections has no voltage anymore). Before opening, be sure that there is no
current to prevent damage to the contactor.
3.7. Gas exhaust
In case of abusive situations, electrochemical cells may open and dissipate hot gases under
pressure. Battery must be located in a room, where people are not staying permanently (with
ventilation if the room volume is less than 25m
3
).
