Installing KRT-4
KRT-4 can be installed in the following ways:
- Attaching KRT-4 to the Underside of a Table, on page 5.
- Attaching KRT-4 to a TBUS, on page 6.
Attaching KRT-4 to the Underside of a Table
You can mount KRT-4 to the underside surface of a table and use it as a standalone device.
To attach KRT-4 under a table:
- Place KRT-4 under the table in the desired location. Make sure that the retracting cable faces the edge of the table.
- Pass the 3 4×50 Philips screws through the table screw openings (4)and tighten them to fix the retractor under the table.
Attaching KRT-4 to a TBUS
You can attach one or more KRT-4 units to the enclosure of any modular Kramer TBUS with pass-through inserts that are installed inside a table. The KRT-4 units can usually be attached to the front and rear sides of the enclosure, as the left and right sides are fitted with clamps. Alternatively, the clamps can be installed on the front and rear sides to enable attaching KRT-4 to the left and right sides of the TBUS enclosure.
For TBUS models with a sliding lid (for example, TBUS-10xl), you can only use the front side of the enclosure to mount the KRT-4 units.
Attaching a Single KRT-4 UnitTo Attach the KRT-4 to a TBUS unit:
1. Slide the KRT-4 onto one of the sides of the TBUS enclosure. Make sure to position the fixed cable (3) downwards and the retractor cable (7) upwards.
2. Use the wing-head thumbscrew to fix the KRT-4 firmly in place.
3. Attach the WCP-(KRT) insert in the following way:
a. Insert the cable through the bushing opening.b. Insert the cable by bushing through the insert opening.c. Push the bushing into the insert opening.
d. Use the two M3x5 screws to attach the insert to the TBUS opening.
The KRT-4 is now firmly fixed in place.
Attaching Several KRT-4 UnitsYou can attach several KRT-4 units to a Kramer TBUS:
- For TBUS units with a sliding cover (for example, the Kramer TBUS-10xl), attach the KRT-4 units side-by-side to the front side of the TBUS enclosure (Figure 7):
- For TBUS units with a regular cover (for example, the Kramer TBUS-1Axl), attach the KRT-4 units side-by-side to the front and rear side of the TBUS enclosure (Figure 8).
To maximize the number of KRT-4 units that can be attached to TBUS-1AXL, TBUS-1-KWC or TBUS-1N, use an inner frame that does not include single or dual power sockets or alternatively, install T-2INSERT/T-4INSERT in the single/dual power socket opening.
Connecting to the KRT-4
You can connect the following devices to the KRT-4.
