Door of the chamber is heavy
The center of gravity moves with the door when you open it. If the chamber topples, it
can cause severe injuries, even death.
If the chamber sits on rails in a rack, the shift of the center of gravity is enhanced when
you slide the chamber out of the rack and open the door at the same time.
Moving door
When you trigger the closing of the door, the door starts closing with reduced force. A
built-in soft-close mechanism prevents the door from closing with full force as long as
the gap is large enough to put a finger in it, maximum 8
mm. But if this safety mecha-
nism fails, and the door closes with full force with a finger between the door and door
frame, the finger is crushed. Even the loss of the limb is possible.
The safety mechanism is described in detail in Chapter 3.2, "Automatic Emergency
Deactivation" , on page 15.
Accidentally disabled soft-close mechanism
A safety cap ( Figure 6-10 ) on the [X21] connector protects the pins of this connector.
The connector is at the rear in the supply and control panel, labeled 3 in Figure 4-3 . If
the safety cap is missing, an accidental short-circuit of these pins can disable the soft-
close mechanism. Without safety mechanism, the door closes completely with full
force. A finger between the door and door frame is crushed. Even the loss of the limb
is possible.
Therefore, always keep the connector [X21] covered; either by the safety cap, or by the
connector of the push-button switch unit (
Figure 4-4 ).
Electrically powered
The risks, requirements for installation and safety measures are described in "Connect-
ing to power" on page 12.
Pneumatically operated door
Supply the compressed air for the pneumatic system at a pressure of 6 bar. If the pres-
sure exceeds the limit of 7 bar, the chamber operates under unspecified conditions.
When operating the door at > 7 bar, uncontrolled situations can occur, causing injuries
like crushed fingers. See Chapter 6.4, "Connecting Compressed Air" , on page 31.
2.3 Potentially Dangerous Situations
Potentially dangerous situations can occur during the following activities.
Transport
Wear appropriate protective clothing that complies with your local rules and regula-
tions. If you are unsure of which equipment to use, ask your safety inspector. For
example, gloves help to keep a tight grip on the handles when carrying the chamber.
