6. Installation and connection

Only install and operate the pumps under the pneumatic operating

parameters and conditions described in Chapter 4, Technical Data.

Observe the safety precautions (see Chapter 3).

6.1. Installation of the pump

 Choose a safe location (flat surface) for the pump.

 Before installation, store the pump at the installation location to

bring it up to ambient temperature.

 See Fig. 3 for mounting dimensions.

Fig. 3: Mounting dimensions PJ25481-950.50.18 (All dimensional toler-

ances conform to DIN ISO 2768-1, Tolerance Class V)

 Install the pump so that the motor fan can intake sufficient

cooling air.

 Make sure that the installation location is dry and the pump is

protected against rain, splash, hose and drip water as well as

other pollutions.

 Make sure, that the installation location is accessible for

maintenance and service.

The IP protection class of the pump motor is indicated on the

type plate.

 Install the pump at the highest point in the system to prevent

condensate from collecting in the pump head.

 Protect the pump from dust.

 Protect the pump against grease and oils.

 Protect the pump from vibrations and jolts.

WARNING

Personal injury and/or damage to property because

of vibration

In conjunction with adjacent components, vibration of

the pump may result in crushing and/or damage to

these components.



Make sure that vibrations of the pump do not re-

sult in hazards associated with adjacent compo-

nents.

 Protect the pump against contact and intrusion of foreign mat-

ter.

6.2. Electrical connection

DANGER

Extreme danger from electrical shock

 Only have the pump connected by an authorized

specialist.



Only have the pump connected when the power

supply is disconnected.

 When connecting the device to a power source, the relevant

standards, directives, regulations, and technical standards

must be observed.

Connecting pump

1. Compare the supply data with the data on the motor plate. For

maximum operating current of the pump see pump’s type

plate.

The voltage must not vary by more than + 10% and – 10%

from that shown on the type plate.

2. Insert the mains cable plug into a properly installed shockproof

socket.

Ensure sufficient dimensioning of the connection cables.

6.3. Pneumatic connection

CAUTION

Personal injury or damages to property by ejected

protective

plugs

If the

protective plug at the pressure side of the

pump hasn’t been removed, it could be ejected be-

cause of the overpressure during operation.



Remove the protective plug during the installa-

tion.

 Only connect components to the pump which are designed for

the pneumatic data of the pump (see Chapter 4, Technical

Data).

 If the pump s used as a vacuum pump, safely discharge the

pump exhaust at the pump’s pneumatic outlet.
