and castors/levelling feet ed), item 19.

3.8 Connect to the emergency stop circuit

Note:

If not connecng to own control equipment, the external EMS link plug supplied to the

EMS connecon on the rear of the dry pumping system must be ed. Failure to do so

will result in not being able to operate the dry pumping system. Refer to (Figure: The

controls/connectors on the rear of the pump (system with rear exhaust and castors/

levelling feet ed), item 22).

If required, customer's control equipment can be connected to the dry pumping system

to shut it down in an emergency using the EMS connecon. The emergency stop control

must be compliant with IEC 60947-5-1. This should be a red self‑latching mushroom

push buon on a yellow background. Refer to (Figure: The controls/connectors on the

rear of the pump (system with rear exhaust and castors/levelling feet ed), item 22).

3.9 Connect and set up the cooling water

WARNING:

Do not turn on the cooling water supply unl the compleon of the electrical

installaon of the dry pumping system or condensaon may form inside the

enclosure and there may be a risk of electric shock.

CAUTION:

Remove both the outer dust caps and inner plasc plugs from the water inlet and

outlet ngs before connecng the cooling water hoses.

CAUTION:

Do not apply excessive torque to the water ngs when connecng the water supply

to the dry pumping system as this may cause damage to the manifold. Use a suitable

spanner to prevent the bulkhead ngs on the dry pumping system from turning

while ghtening up the connectors.

CAUTION:

Fit the inlet strainer (supplied Y strainer) into the supply side of the cooling water

system to prevent damage to the cooling system within the dry pumping system.

Notes:

1. For opmum water cooling, ensure that the cooling water supply meets the

specicaon given in Cooling-water data on page 25. Ensure that the water supplies are

connected in parallel. Refer to Figure: The controls/connectors on the rear of the pump

(system with rear exhaust and castors/levelling feet ed), items 17 and 13.
