1. MOUNTING
• Ground the unit by connecting the ground plate
to the ship's body with the hex. bolt.
• Apply the supplied silicone grease between the
docking module and storage module to prevent
water from entering (see the figure at step 3 on
page 1-10).
The silicone grease is supplied with the float-free
DRU. The grease is marked as "Item no.88237
Tron-40VDR". After applying the silicone grease,
do not release the capsule from the bracket other
than the maintenance. If you release the capsule,
apply the silicone grease again when reattach it.
• Do not remove the vinyl protective cover on the
cable connector until you connect the cable to the float-free DRU.
When the float-free DRU serial number is "20-0001" or later, the float-free DRU ca-
ble is separated from the capsule and the vinyl protective cover is attached to the
cable connector. If the connector is damaged or worn, a communication error may
occur. Therefore, keep the vinyl protective cover attached until you can connect the
cable to the float-free DRU.
• Do not bend and/or twist the cable excessively to secure the cable. Ensure a mini-
mum bend radius of 80 mm.
