Figure 7.3 Remote Emergency OFF Switch Cabling
The remote emergency stop input uses a normally-closed contact which opens to trigger the emergency stop sequence.
In order to allow maintenance or testing of the remote emergency stop circuit without disturbing the normal UPS operation
it is recommended that a terminal block with linking facilities is installed between the UPS and the remote emergency stop
button, as shown.
1. Use a screened cable with 1 pair (section of wires 0.6 mm
2
) and maximum length of 100 m.
2. Connect the cable as shown in Figure 7.3.
