delivered accessories (5) and (6).

Oil injection control dismantling

Remove the clip-on coil by using a screw driver.

The compressor must only be used for its designed purpose(s) and within its scope of application (refer to «operating limits»).

Consult Application guidelines and datasheet available from http://cc.danfoss.com

Under all circumstances, the EN378 (or other applicable local safety regulation) requirements must be fulfilled.

The compressor is delivered under nitrogen gas pressure (between 0.3 and 0.7 bar) and hence cannot be connected as is; refer to the «assembly» section for further details.

The compressor must be handled with caution in the vertical position (maximum offset from the vertical : 15°)

Instructions

-Depending on the frequency converter version, the physical position of individual connectors may differ from below diagram.

-Always make sure that the compressor terminals T1, T2, T3 are connected to the frequency converter terminals 96, 97, 98 respectively.

-The compressor motor cable must be shielded

Basic connections

and the armoured part must be connected to ground on both cable ends; at the side of the compressor and at the side of the frequency converter.

-Use an EMC cable gland for cable installation and perfect grounding; The metallic terminal box of the compressor has a paint-free surface around

-A low pressure safety switch is mandatory to avoid compressor vacuum operation.

-At start-up, verfiy that the compressor rotates in the right direction and pumps.

The CDS302 frequency converter is factory preset with parameters for the open loop control principle. The process loop control principle can be selected by changing parameters in the «Quick menu».

Open loop:

0 - 10 V control

Frequency converter in slave mode

Process loop:

4 - 20 mA control

Frequency converter under own PID controller

- Optional connection

X : Mandatory connection
