Mechanical assembly

1. Place the product so that the filter for the breathing opening 4 is not covered.
2. Fasten the product with two M5 screws via the through holes 6 or with two M5 screws via the
fastening thread.
3. Install two 3/2-way push-button valves (è Fig. 2).
Caution
Any attempt to actuate the push-button valves with only one hand or with an elbow, a
knee or a foot will impede the safety function (è Fig. 4).
• Make sure the requirements for setting up two-hand push-button switching circuits
as per EN 574 are observed, e.g. by specifying the minimum distance between the
push-buttons.
• If necessary, take into account existing C-standards for your type of machine.
• Implement the measures as per EN 574.

Pneumatic fitting

1. Remove the transport covers on the compressed air connections.
2. Connect the tubing with the specified components (è Tab. 1).
Note
The product will function as intended providing it is set up correctly and if the
exhausting is correct.
• Use the same lengths of tubing between the push-button valves and the two-hand
control unit.
• Secure the hoses to the system to prevent them from moving in an uncontrolled
manner.
• Use only 3/2-way push-button valves.
• The outlet ports 3 must remain open to allow venting of the push-button valves.
Use a suitable silencer if required.
• If required, use a suitable silencer at outlet port 3 of the control block for two-hand
start (è www.festo.com/catalogue/zsb).
• Replace contaminated silencers if necessary.
