NOTE
The MOBILETT may be turned on only if all battery packs BK1 -
BK4 are connected to D982.
If one or more battery packs are not plugged in when the MOBI-
LETT is turned on, fuse F3 and/or F4 on D982 fails.
24 batteries at 12 V/7 Ah Pb, grouped to form 4 battery packs (BK1-BK4), divided in the
left blocks (BK1&BK2) and the right blocks (BK3&BK4), for the battery unit. Each battery
block is assigned a charger of D982.
Charger 1 of D982 supplies left battery blocks BK1 & BK2. Charger 2 of D982 supplies
right battery blocks BK3 & BK4.
A complete battery block must always be replaced in the case of an error.
