2.
Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.
C.
INSTALLATION OF M1 AND M2 SYSTEMS:
See Figure 4 for a typical installation of the M1 and M2 System onto a monopole. The top bracket should be
positioned to allow users safe access when connecting or disconnecting from the system. The top brackets are to be
connected to the structure with a 3M DBI-SALA standoff or customer supplied stand-off support. Stand-off supports
must support the loads specified in section 2.2, and must be compatible with the LAD-SAF
Angle Leg and Round Leg Stand-off Installation:
See Figure 5 for the installation of the angle (A) and round leg (B) stand-off supports. Install stand-off supports using
the hardware provided. Do not substitute other fasteners. Torque 3/8-inch fasteners to 20-25 ft-lb. (27-34 N-m).
Install the top bracket to the stand-off support using the 1/2-inch fasteners provided. Torque 1/2-inch fasteners to
40-45 ft-lb. (54-61 N-m).
Weld-on Stand-off Installation:
Install the stand-off support (C) as shown in Figure 5. See section 3.2 for welding recommendations. The stand-off
must be perpendicular to the pole surface and in-line with the carrier cable.
; Installations that use the angle leg or round leg stand-off support brackets are limited to one user on the system at a time.
M1 and M2 System Installation:
See Figure 4. Installation procedure:
1.
Top Bracket: Install top plate (A), hardware (B) and Single Point Anchor assembly (C) as shown in Figure 4.
Slide the D-Ring (D) over the assembly (C) before installing. Torque fasteners as specified.
2.
Bottom Bracket: Install bolt, spacers and fasteners as shown. Torque fasteners as specified.
D.
INSTALLATION OF W1 SYSTEM:
See Figure 7 for a typical installation of the W1 System on a wooden pole. The top bracket should be positioned to
allow users safe access when connecting or disconnecting from the system. Use 1/2-inch fasteners (not provided)
to attach the top bracket to the pole. Fasteners should extend through the pole when possible. 3M DBI-SALA
recommends using lock washers, double nuts, or other methods to ensure fasteners will not loosen.
E.
INSTALLATION OF CE1 SYSTEM:
See Figure 8 for a typical installation of the CE1 System. The top bracket should be positioned to allow users safe
access when connecting or disconnecting from the system.
Installation procedure:
1.
Top Bracket: Slide rung clamps (B) over tube and install fasteners as shown. Torque fasteners as specified.
2.
Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.
F.
INSTALLATION OF T1 SYSTEM:
See Figure 9 for a typical installation of the T1 System. The top bracket should be positioned to allow users safe
access when connecting or disconnecting from the system. Typical applications include access ladders into manholes
or under trap doors. Do not substitute other fasteners.
Installation procedure:
1.
Top Bracket: Install clamp plates and fasteners as shown. Torque fasteners as specified.
2.
Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.
3.7
INSTALLATION OF CARRIER CABLE ASSEMBLY TO TOP BRACKET:
A.
INSTALLATION OF CARRIER CABLE ASSEMBLY:
1.
Lay the carrier cable assembly out on the ground in a clean area by rolling the coil. Do not pull cable from center
of coil. For some installations it may be easier to lower the carrier cable from the top connection level down to the
bottom bracket. If so, carefully lower the cable by unspooling without twisting the cable at the top connection. Do
not drop the cable to the lower level.
; Carrier cable is very stiff and may spring out of coil unexpectedly. Use proper safety procedures when unrolling
cable. Use appropriate safety gear, including gloves and safety glasses, when unrolling cable.
Inspect the cable for shipping damage before proceeding. Do not install damaged cable.
2.
See Figure 11 for installation of the carrier cable into the top bracket. Ensure the end of cable is free of kinks and
unraveled strands.
Installation procedure: Insert lug end (C) of carrier cable assembly into the side of the top plate (B) profile at an
approximate angle of 45 degrees while pressing against spring gate (D). The small pin (E) and spring gate (D) are
designed to prevent the lug/cable assembly from inadvertently disconnecting from the top plate (B). Make certain
that only the large pin (A) rests inside the top plate (B).
3.8
INSTALLATION OF CABLE GUIDES, ALL MODELS:
Cable guides protect the carrier cable from chafing against the structure and to prevent the climber from excessively
deflecting the cable from side to side. Cable guides should be positioned at approximately 20-40 ft (6-12m) along the
carrier cable between the top and bottom brackets, and at any point along the system where the cable may abrade
against the structure. Cable guides should be staggered along the system to reduce harmonic effects of the wind, such as
at 23 (7.01), 25 (7.61), and 27 (8.23) feet (m) intervals. For high wind areas, "L" shaped cable guides may be used. The
"L" shaped cable guides should be alternated with openings on the left, then right, etc., up the structure. Latching cable
guides are also available.
Direct Connection to Structure:
