Mounting Location Considerations - Garmin CLASS B COMPACT Installation Instructions Manual

Mounting Location Considerations

This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The
temperature range for this device is listed in the product specifications. Extended exposure to temperatures
exceeding the specified temperature range, in storage or operating conditions, may cause device failure.
Extreme-temperature-induced damage and related consequences are not covered by the warranty.
The drive unit must be installed within specific extension and angle limitations, as mentioned below and defined
in the specifications at the end of these instructions. Exceeding the extension or angle limitations will damage
the drive unit. Installation-related damage is not covered by the warranty.
The position feedback sensor on the drive unit may be affected by magnetic interference. Installing the drive
unit in close proximity to a magnetic device may result in poor product performance.
When selecting a mounting location, observe these considerations.
• The drive unit must be installed under deck, in a location not subject to flooding or washdown.
• The drive unit must be mounted securely on a surface that is able to withstand the high thrusts generated by
the rudder.
• The drive unit movement must be limited by physical stops, and not by the length of the drive unit rod, or
damage to the drive unit will occur.
• No part of the drive unit or rod should contact the vessel, quadrant, or tiller arm throughout the full range of
movement.
• You must not exceed the 10 degree tilt at the extremes of the stroke, because it will damage the drive unit.
• The drive unit must not be installed in a location that is near strong magnetic interference, such as near the
back of a speaker or subwoofer.
◦ Safe mounting distance from a typical marine speaker is at least 20 cm (8 in.).
◦ Safe mounting distance from other devices can be estimated by multiplying their specified compass-safe
distance measurement by 0.05.
Tiller Arm and End Stop Considerations
You can connect the drive unit to either an existing quadrant or to a tiller arm (not included). If you do not have
a quadrant or cannot install the drive unit at your quadrant location, choose a tiller arm that fits the diameter of
your rudder post and is the correct length for the installation location.
The supplied tiller bolt is suitable for a quadrant or tiller arm thickness of 12 mm (0.47 in.) to 16 mm (0.63 in.).
The drive unit must not act as a rudder-movement limiter. Physical end stops (not included) must be in place to
limit the drive-unit travel to 254 mm (10 in.) from fully retracted to fully extended, or damage to the drive unit will
occur.
Mounting the Drive Unit
Hardware is supplied to fasten the drive unit to the mounting surface. The supplied M8 bolts, washers, and nuts
are suitable for mounting the cylinder on a surface between 12 mm (0.47 in.) and 24 mm (0.95 in.) thick.
1 With the drive unit in the mounting location, mark the locations of the four mounting holes on the surface.
2 Verify the marked locations.
The marked locations should be 76.2 mm (3 in.) apart .
3 Drill 8.8 mm (0.35 in.) holes through the mounting surface.
4 Secure the drive unit to the mounting surface using the supplied M8 bolts, washers, and nuts.
5 Tighten the bolts to 17 Nm (12.5 ft-lbf).
