Skilled technicians familiar with vacuum equipment must perform the installation of this equipment. Edwards
recommends that you read the safety booklet P400-40-100.
5.3.1

Check and configure the motor: single and three phase pumps

Ensure that the motor is correctly configured for your electrical supply. If you operate the pump when the motor
is not correctly configured for the electrical supply, you will damage the motor.
Note: Edwards does not supply the motor cable gland. Therefore the customer must provide an 'EEx-d' certified
cable gland to maintain the integrity of the flameproof motor.
1. Remove the screws that secure the cover of the motor terminal-box using a 5 mm hexagonal key.
2. Fit an 'EEx-d' certified cable gland. Refer to
Pump type
RV3, 5, 8, 12 and EM18, 28
EM40, 80
EM175, 275
3. Ensure that the motor is correctly rated and configured for your electrical supply. Refer to the motor
manufacturer's wiring diagram supplied inside the motor terminal box lid. If necessary, reconfigure the links to
suit your electrical supply.
5.3.2

Connect the pump to your electrical supply

Ensure that the electrical installation of the pump conforms to your local and national safety
requirements. It must be connected to a suitably fused and protected electrical supply with a
suitable earth point.
Connect the motor to the electrical supply in accordance with the manufacturer's recommended installation
instructions supplied with the motor. In addition, the following points must be observed.
You must use a suitable electrical supply cable.
You must use a flameproof cable gland, certified to 'EEx-d'.
Connect the electrical supply to the motor through a starter or circuit breaker, which has thermal over
current protection.
You must connect the thermal protection devices. This is an ATEX requirement and must be performed to
maintain certification. See
We recommend that you connect the motor to the electrical supply through suitable control equipment that
requires a manual reset after an electrical supply failure. If you do not, the pump will restart when the
supply is restored.
