Installation and Setup
23
4.8.1 – Side Bracket Attachment
To attach side mounting brackets:
1. Verify that the PTU ‐ D300 has been powered on and allowed to reset, which places the
mounting hub in its “home” position.
2. Power off the PTU ‐ D300.
3. Orient the bracket so the horizontal mounting arm is on the bottom.
4. Attach the bracket using 6 screws torque to 32 inch ‐ pounds. The thread holes in the hub
come with thread locking compound applied to them. Reapply thread lock to the hub
whenever you remove the bracket using a compound such as Loctite® 242.
5. Reset the PTU ‐ D300 and ensure that the bracket moves properly throughout the entire
range of motion.
Note: If you ordered your PTU ‐ D300 with a top bracket, the unit will arrive with the
bracket already attached.
4.8.2 – Payload Attachment
The following guidelines apply to all payload attachments:

Mount all payloads as close to the PTU ‐ D300 as possible. This minimizes the distance
between the payload Center of Gravity (CG) and the center of rotation of the axes, which
reduces stress on the PTU ‐ D300 unit and mounting. It also improves performance by
reducing the amount of torque required to move the payload.

Verify that the payload will clear the PTU ‐ D300 housing and all surrounding objects
throughout the entire range of motion.

The PTU ‐ D300 is rated for a maximum load of 70 lbs; however, load distribution affects the
actual weight that the PTU ‐ D300 can safely move. The amount of torque needed to move a
payload depends on a number of factors such as payload weight, distance from the payload
CG to the center of rotation, acceleration and speed settings, power levels, environmental
factors, etc.

The PTU ‐ D300 allows full control over acceleration, speed, and power levels. Mount your
payload and configure these parameters appropriately to ensure reliable operation.
