1 T-slot height modification
2 T-nut (Pack 104)
3 Header
4 Horton T-slot
1.1 Existing header T-bolts
Move exiting header T-bolts to right and left hand ends of header.
1.2 Increase height of header T-slot.
1. Increase height of T-slot in a location near one side of header.
• Recommended tool: 7/8" to 1-1/8" Unibit.
• Horton headers use top T-slot for mounting backplate and return pulley assemblies (Fig. 2)
TIPS AND RECOMMENDATIONS
Expansion of T-slot height is necessary to install T-nuts (Fig. 1.3).
2. 115 VAC wiring termination location
2.1 Header 115 VAC wiring location.
1. 115 VAC wiring will terminate at backplate DC power supply location (Fig. 6.3.1 as an example).
2. If required, extend existing 115 VAC wiring to DC power supply location before proceding.
3. Insert T-nuts into header T-slot

4.1 Place backplate assembly (Chapter 5)into header.
1. Place backplate assembly into header.
CAUTION
Seven to eight inches of space next to DC power supply 115 VAC receptacle (Fig. 10.) is required
for installing and removing 115 VAC plug (Fig 11) and wiring.
2. Position installed T-nuts (Para. 6.3.1) in approximate backplate T slot locations 2.1, 2.2, and 2.3 (Fig. 7).
4.2 Install backplate over special T-bolt.
Special T-bolt (Fig. 9) will be used as a ground connection.
1. Insert special T-bolt in header T-slot next to DC power supply (Fig 10).
2. Install backplate slot next to DC power supply 115 VAC connection (Fig. 10) over special T-bolt.
3. Place backplate ground wire lug over special T-bolt.
4. Thread nut (Fig. 11) onto special T-bolt but do not fully tighten.
