Connect an additional RF earth (ground) (optional)

If you will operate the system in an area subject to high RF (radio frequency) emissions, in accordance with good RF
installation practice, we recommend that you:
Use a star washer to connect the end of the earth (ground) cable
inlet to one of the bolts that you use to secure the inlet-flange.
Connect an additional earth (ground) cable to the RF earth (ground) stud
suitable low-impedance cable (for example, use braided cable).

Connect to your emergency stop circuit

The EMS (Emergency Stop) button on the front panel of the system (Figure 2, item 1) is used to stop the pump in an
emergency.
Note:
Used on its own, the EMS does not isolate the electrical supply to the pumping system and so does not
provide an EMO (Emergency Off) function.
The pumping system has an external emergency stop circuit that can be connected into your own control equipment.
(In this case, the emergency stop control should be compliant with IEC 60947-5-1, a red self-latching mushroom push
button on a yellow background).
If you wish to operate the pumping system without connecting it to your own control equipment you must fit the
external EMS link plug (supplied) to the EMS connection on the rear of the system
fit the EMS link plug the system will not operate.
If you require EMO functionality (for example, to satisfy the requirements of Semi S2) you can install the pumping
system in combination with an Edwards Disconnect Box (available as an accessory, refer to
Disconnect Box manual for installation instructions and information about the different ways the pumping system can
be shut down in an emergency.
For pumps that are installed into an integrated system and receive their power from that system, an emergency off
can be achieved by connecting the emergency stop circuit on the pump into the integrated system's emergency off
circuit.
