Installation and clamping method

■

Installation direction

Installation should be done so that the cable gland is oriented toward the stern.

■

Bolts, nuts and tightening torque to be used

■ Use stainless steel bolts for the scanner and uniformly tighten all of the bolts using

double nuts for each bolt so that the scanner will not become loose (Table 1-2-1).

■ Although the length of the bolt will differ according to the thickness of the mount

base, use a bolt long enough so that more than 4 millimeters of thread protrudes

beyond the double nuts after the double nuts have been tightened.

Use of washer and corrosion-resistant measures

■ At the location where a bolt's head or nut comes in contact with the scanner chassis'

legs and the mount base, insert a plain washer which fits the bolt; and, at the location

where the nut comes in contact with the plain washer, insert a spring washer, and

then securely tighten the nuts .

■ To prevent corrosion due to the contacts between different metals, such as the

scanner chassis' legs, installation surface, bolts, nuts, etc., cover the bolt's head and

nuts with sealant .

■

Grounding and corrosion-resistant measures

■ Do not install the scanner in place where puddles are often formed.
