2.1 COMPATIBILITY OF COMPONENTS: DBI‑SALA equipment is designed for use with DBI‑SALA approved components and subsystems only. Substitutions or replacements made with non‑approved components

or subsystems may jeopardize compatibility of equipment and may effect the safety and reliability of the

complete system.

2.2 COMPATIBILITY OF CONNECTORS:

elements when they have been designed to work together in such a way that their sizes and shapes do not cause their gate mechanisms to inadvertently open regardless of how they become oriented. Contact DBI‑SALA if you have any questions about compatibility.

Connectors (hooks, carabiners, and D‑rings) must be capable of supporting at least 5,000 lbs. (22.2 kN). Connectors must be compatible with the anchorage or other system components. Do not use equipment that is not compatible. Non‑compatible connectors may unintentionally disengage. See Figure 3. Connectors must be compatible in size, shape, and strength. Self locking snap hooks and carabiners are required by ANSI Z359.1 and OSHA and CSA Z259.12 in Canada.

2.3 MAKING CONNECTIONS: Only use self‑locking snap hooks and carabiners with this equipment. Only use connectors that are suitable to each application. Ensure all connections are compatible in size, shape and strength. Do not use equipment that is not compatible. Ensure all connectors are fully closed and locked.

Connectors are considered to be compatible with connecting

Figure 3 - Unintentional Disengagement (Roll-out)

If the connecting element that a snap hook (shown) or carabiner attaches to is undersized or irregular in shape, a situation

could occur where the connecting element applies a force to the gate of the snap hook or carabiner. This force may cause the gate (of either a self‑locking or a non‑locking snap hook) to open, allowing the snap hook or carabiner to disengage from the connecting point.

Small ring or other

non‑compatibly

shaped element

1. Force is applied to the snap hook.

2. The gate presses against the connecting ring.

3. The gate opens allowing the snap hook to slip off.

DBI‑SALA connectors (snap hooks and carabiners) are designed to be used only as specied in each product’s user’s instructions. See Figure 4 for inappropriate connections. DBI‑SALA snap hooks and carabiners should not be connected:

A. To a D‑ring to which another connector is attached.

B. In a manner that would result in a

Figure 4 - Inappropriate Connections

load on the gate.

note: Large throat snap hooks should

not be connected to standard size D‑rings or similar objects which will result in a load on the gate if the hook or D‑ring twists or rotates. Large throat snap hooks

are designed for use on xed structural

elements such as rebar or cross members that are not shaped in a way that can capture the gate of the hook.

In a false engagement, where

features that protrude from the snap hook or carabiner catch on

the anchor and without visual

confirmation seems to be fully

engaged to the anchor point.

D. To each other.

E. Directly to webbing or rope lanyard or tie‑back (unless the manufacturer’s instructions for both the

lanyard and connector specifically allows such a connection).

F. To any object which is shaped or dimensioned such that the snap hook or carabiner will not close and

lock, or that roll‑out could occur.

2.4 INSTALLATION LOAD: The surface on which the Perimeter Limiter is installed must be capable of

supporting the weight of the unit and fall arrest loads. The maximum static load is 470 lbs. (213 kg), the maximum foot pad loading during fall arrest for one user is 1,200 lbs. (545 kg) and 2000 lbs. (900 kg) for two users. See section 7, for the weight of each Perimeter Limiter model.

3.0 asseMbly anD Use

warnIng: Do not alter or intentionally misuse this equipment. Consult with DBI‑SALA if using this equipment

in combination with components or subsystems other than those described in this manual. Some subsystems and components combinations may interfere with the proper operation of this equipment. Use caution when using this equipment around moving machinery, electrical and chemical hazards, and sharp edges.

warnIng: Working at height has inherent risks. Some risks are noted here but are not limited to the following:

falling, suspension/prolonged suspension, striking objects, and unconsciousness. In the event of a fall arrest and/ or subsequent rescue (emergency) situation, some personal medical conditions may affect your safety. Medical

conditions identied as risky for this type of activity include but are not limited to the following: heart disease,

high blood pressure, vertigo, epilepsy, drug or alcohol dependence, psychiatric illness, impaired limb function

and balance issues. We recommend that your employer/physician determine if you are t to handle normal and

emergency use of this equipment.

3.1 BEFORE

EACH USE inspect this equipment according to steps listed in section 5. Do not use this equipment

if inspection reveals an unsafe or defective condition. Plan your use of the fall protection system prior to exposing workers to dangerous situations. Consider all factors affecting your safety before using this system.

Read and understand all manufacturer’s instructions for each component of the personal fall arrest system. All DBI‑SALA harnesses and connecting subsystems are supplied with separate user instructions. Keep all instructions for future reference.

3.2

PLAN your fall arrest system before starting your work. Take into consideration factors affecting your safety at any

time during use. The following list gives some important points you must consider when planning your system:

A. SURFACE STRUCTURE: The surface structure must be capable of supporting the required loads. See

section 2.4.

B. OTHER CONSIDERATIONS:

Figure 5 - Safe Work Zone

• Always work within the safe work zone of the

Perimeter Limiter to avoid the possibility of rocking or tipping the unit. See Figure 5.

• Personal fall arrest systems must be rigged to limit

any free fall to a maximum of 6 ft. (1.8 m) (OSHA and ANSI Z359.1) (see section 1.2 F).

2 ft. Min

(.3 m Min)

Leading Edge

Front

• Do not work above the surface of the Perimeter Limiter level since an increased free fall distance will result.

• Avoid working where your line may cross or tangle with that of another worker or another object.

• Do not allow the lifeline to pass under arms or

between legs.

26 ft. Max

(7.9 m Max)

Perimeter Limiter Safe

Work Zone

Side

• Never clamp, knot or otherwise prevent the lifeline from retracting or being taut, avoid slack line.

• The Perimeter Limiter has two shackles designed for lifting the unit: one on the gusset at the base of the

mast and the other on the top center of the weight cart. See Figure 1. Use these shackles for lifting the unit to the work area. Always use both shackles when lifting the unit.

warnIng:

Do not attach a personal fall arrest system to the lifting shackles. The shackles are not rated for fall

arrest and in the event of a fall, serious injury or death could occur.

24 ft. Max

(7.9 m Max)

IMPortant: Do not lengthen the SRL lifeline by connecting a lanyard or similar component without consulting

DBI‑SALA.

C. TOTAL FALL DISTANCE: Should a fall occur, there must be sufficient clearance in the fall area to arrest

the fall before striking the ground or other object. The total fall distance is the distance measured from the onset of a fall to the point where the fall is arrested. A number of factors can influence the total fall distance including; user’s weight, anchorage location relative to the fall (swing fall), body support with sliding D‑ring, and the type of fall arrest equipment you attach to the anchor. For specific clearance requirements read and follow the manufacturers’s instructions for your fall arrest equipment.

D. SWING FALLS: See Figure 6. Swing falls occur when

the anchorage point is not directly above the point where a fall occurs. The force of striking an object

while swinging (horizontal speed of the user due to the pendulum affect) can be great and may cause serious

injury. Swing falls can be minimized by working as close to the anchorage point as possible. In a swing fall situation, the total vertical fall distance of the user will be greater than if the user had fallen vertically directly below the anchorage point. The user must therefore

account for an increase in the total free fall distance

and the area needed to safely arrest the fall.

E. SHARP EDGES:

Avoid working where the connecting

subsystem (i.e. self retracting lifeline (SRL), full body harness, lanyard, lifeline, etc.) or other system

components will be in contact with, or abrade against

unprotected sharp edges. See Figure 7. If working with this equipment near sharp edges is unavoidable, protection against cutting must be provided by using a heavy pad or other means over the exposed sharp edge. If you are not using the Leading Edge SRL (PN 3504500 or 3504600), it is recommended that an energy absorber (PN 1220362) be installed in‑line

between the harness and the self retracting lifeline

to further protect the worker. Compatibility and total fall distance issues must be considered if this is done. Contact DBI‑SALA before using in‑line energy absorbing components or lanyards with self retracting lifelines.

Figure 6 - Swing Falls

Unexpected Hazards

F. RESCUE: When using this equipment, the employer

must have a rescue plan and the means at hand to

implement it and must communicate that plan to users,

authorized persons, and rescuers.

G. AFTER A FALL: Any equipment which has been

subjected to the forces of arresting a fall or exhibits damage consistent with the effect of fall arrest forces as

described in section 5, must be removed from service

immediately and destroyed by the user, the rescuer, or

an authorized person.

warnIng: Read and follow the manufacturer’s instructions

for associated equipment (i.e. SRL, full body harness, lanyard, lifeline, etc.) used in your personal fall arrest system.

3.3 SYSTEM ASSEMBLY: Figure 1 shows the Perimeter Limiter

Anchor assembled. The Perimeter Limiter is shipped with

the mast arm installed backwards

for space saving concerns. When the anchor arrives, remove

the bolt that goes through the

mast and arm, remove the arm and rotate it 180° to its proper orientation and replace it. Then

replace the bolt through the arm and mast and tighten the nut with

a wrench.

warnIng: The Perimeter Limiter

Anchor system must only be used with

the arm extending in the direction

opposite the weight cart within 45° (see Figure 8). Any other orientation will diminish the effectiveness to the counterweight system and use could result in severe injury or death.

3.4 OPERATION

Step 1. Position the Unit: Use the positioning handles on the rear of the weight cart and positioning bars

on the front of the unit (see Figure 1) to position the unit at the desired work location, within the

requirements of section 3.2.

Step 2. Once the unit is in proper position and alignment, Raise the front and rear tire jacks until the foot

pads reach the work surface. Continue to rotate the jack handles until all three wheels are lifted off the work surface and rotate freely to ensure the weight of the unit is transferred to the foot pads.

Step 3. Attach your personal fall arrest system (PFAS) to the attachments points on the mast arm (see

Figure 1). Refer to the PFAS manufacturer’s instructions for correct attachment and use of the PFAS. Do not attach more than one PFAS to an attachment point. Do not attach more that two PFAS to the Perimeter Limiter.

warnIng: Do not move the Perimeter Limiter while a user is attached to it.

3.5 OPTIONAL MAST FOR 9.5 FT. (2.9 M) CONFIGURATION: If you are retrotting your Perimeter Limiter with the optional 9.5 ft. (2.9 m) mast, remove the mast arm as previously indicated. After the mast arm is removed, remove the bolt at the base of the mast and lift the mast off the base.

Replace the old mast with the new one and replace the original bolt and nut, then place the mast arm on top

of the new mast and replace its bolt and nut. Be sure to tighten both nuts with a wrench to make sure they are snug.

Along with the 9.5 ft (2.9 m) mast, you need to install an additional weight set into the weight box. To install the extra weights, Use the lifting point shackles to raise the Perimeter Limiter about 1 ft. (.3 m) off the ground. Place two of the weights inside the weight box and center them over one of the mounting holes in the permanent weights. Slide one of the supplied long, 1‑in. bolts into the hole from the bottom of the cart and apply the washer and nut to the end of the bolt after it has passed through the two extra weights. Snug the nut down with a wrench. Repeat this procedure with the other two extra weights over the second mounting hole.

warnIng: Do not use the 9.5 ft. mast without installing the additional weights. In the event of a fall without

the additional weights, the anchor could tip causing sever injury or death.

3.6 BODY SUPPORT:

A full body harness must be worn for fall arrest applications. For general fall protection

use, connect to the D‑ring on the back between the shoulders (dorsal D‑ring).

IMPortant: Body belts are not allowed for free fall situations. Body belts increase the risk of injury during fall

arrest in comparison to a full body harness. Limited suspension time and the potential for improperly wearing a body belt may result in added danger to the user’s health.

3.7 OPTIONAL DIGITAL WINCH: If you purchase a Digital

Figure 9 - Digital Winch

Winch, a mounting bracket is shipped with it. To mount the Digital Winch, remove the detent pin from the winch

Detent Pin

mounting bracket, place the slot on the lower edge of the bracket onto the pin on the bracket on the Perimeter Limiter mast and then rotate the winch toward the mast

until the upper holes in the two brackets align. Insert the detent pin through the holes in both brackets. Make sure

the detent pin goes all the way through both brackets and

clicks into place. See Figure 9. Route the winch’s wire rope over the roller at the top of the mast and over the pulley at the center of the mast arm. Refer to the Digital Winch user instruction for proper use and inspection.

3.8 CONNECTING TO THE PERIMETER LIMITER ANCHOR:

Figure 7 illustrates the proper connection of

typical fall arrest equipment to the Perimeter Limiter anchor. Always protect the lifeline from abrading against sharp or abrasive surfaces on the roof. Make sure all the connections are compatible in size, shape and strength. Never connect more than two personal protective system to a Perimeter Limiter at a time.

SRL: Connection to the installed Perimeter Limiter anchor may be made by using a carabiner to attach a

self retracting lifeline (SRL) to one of the anchor points on the mast arm of the Perimeter Limiter and then

attaching the self locking snap hook at the end of the SRL lifeline to the back dorsal D‑ring (fall arrest attachment point) of the user’s body support (i.e. full body harness). When connecting, make sure the connections are fully closed and locked. Review section 3.2 if using an SRL near sharp edges.

ENERGY ABSORBING LANYARDS OR LIFELINE: Connect the energy absorbing end of the lanyard to the

back D‑ring on the full body harness (see section 3.6). See manufacturer’s instruction for more information.
