SAFETY ANALYSIS TECHNIQUES
1. Conduct Hazard Analysis and Risk
Assessment
Refer to:
• OSHA Title 29, ANSI Standards.
• European Norm EN 1050, Safety of Machines
Risk Assessment.
2. Review Requirements and Safety Related
Parts of the Control System
• ANSI B11.19-1990 -- Safeguarding When
Referenced by the Other B11 Machine Tool
Safety Standards.
• ANSI B11.20 -- System Energy Stopping.
• European Norms:
− EN954-1: Safety Related Parts of the Control
Systems.
− EN60204-1: Electrical Equipment of Machines.
− prEN1088: Interlocking Devices With and
Without Guard Locking.
• Any other appropriate industry safety standards.
PERFORM INSTALLATION AS FOLLOWS:
1. Assemble Switch Head (applies to Head
Option "E" and "K" only)
The one-way screws must be used on this head
option to prevent voiding the warranty.
Head options "E" and "K" are shipped unattached
and may be indexed in 90° increments (Figure 2).
• Rotate auxiliary release (1) to unlock position.
• Properly seat:
− Factory-installed "O" ring (2) in its seal groove.
− Plunger (3).
• Determine required key entry location.
• Securely fasten operating head to switch housing
with the four one-way screws provided. Torque
screws to 1,36-1,80 N-m (12-16 in-lb).
• Rotate auxiliary release back to lock position.

2. Mount, Wire and Seal Switch
Step 1 - Ensure you have the following:
• Switch and key.
• Wire (use 90°C wire when ambient temperature is
over 75°C):
− Stranded: 0.75 mm
− Solid: 0.75 mm
• M5 or #10 screws.
Step 2 - Mount switch and key:
IMPROPER INSTALLATION
• Ensure key travels to the minimum insertion
dimension to ensure switch contact transfer
(Figure 4).
• Ensure key travels to maximum extraction
distance to ensure correct operation of the
positive break mechanism.
• Do not exceed 100 N (22.4 lb) actuation force to
key to prevent switch failure (Table 1).
• Do not use the key as a stop for the door.
Failure to comply with these instructions
could result in death or serious injury.

*Device is in unlocked state.
• Ensure proper clearance for switch and key at
mounting location so that operation of the auxiliary
release, as well as inspection and replacement,
are possible.
• Properly align switch and key together before
mounting to equipment.
• Mount switch and key (Figures 3 and 4).
− Torque switch to mounting surface: 4,9-5,9 N-m
(43-52 in-lb) M5 or #10.
UNLOCK
− Torque key to mounting surface: 2,4-2,8 N-m
(21-25 in-lb) M5 or #10.
