1 Important Notes

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

1.1 Use of this documentation

The documentation is part of the product and contains important information about in­stallation, startup, operation and service. The documentat ion is written for all employees
who install, startup, and service this product.

The documentation must be accessible and legi ble. Make sure that persons responsible
for the system and its operation, as well as persons wh o work independently on the unit,
have read through the documentation carefully and understood it. If you are unclear
about any of the information in this documentation, or if you require further information,
contact SEW-EURODRIVE.

1.2 Structure of the safety notes

Unless the information in the documentation is adhered to, it will be impossible to
ensure:

• Trouble-free operation

• Fulfillment of any rights to claim under guarantee

Important Notes

Use of this documentation

1

Consequently, read the operating instructions before you start working with the
unit!

The operating instructions contain important information about servicing. Therefore,
keep the operating instructions close to the unit.

1.2.1 Meaning of the signal words

The following table shows the grading and meaning of the signal words for safety notes,
notes on potential risks of damage to propert y, an d ot he r no te s.

Signal Word Meaning Consequences if disregarded

DANGER Imminent danger Severe or fatal

WARNING Possible dangerous situation Severe or fatal

CAUTION Possible dangerous situation Minor injuries

NOTICE Possible damage to property Damage to the drive system or its environ-

1.2.2 Structure of the section safety notes

Important Notes

Structure of the safety notes

The section safety notes do not apply to a specific action, but to several actions pertain­ing to one subject. The pictograms used indicate either a general or a specific hazard.

This is the formal structure of a section safety note:

SIGNAL WORD

Nature and source of hazard.
Possible consequence(s) if disregarded.

• Measure(s) to prevent the hazard.

This is an example of a section safety note:

WARNING

Falling of suspended loads.
Severe or fatal injuries.

• Do not stand under the suspended load.

• Secure the danger zone.

1.2.3 Structure of the embedded safety notes

The embedded safety notes are directly integrated in the instructions just before the
description of the dangerous action.

This is the formal structure of an embedded safety note:

• SIGNAL WORD Nature and source of hazard.
Possible consequence(s) if disregarded.
– Measure(s) to prevent the hazard.

This is an example of an embedded safety note:

• DANGER Risk of crushing if the drive restarts unintentionally.
Severe or fatal injuries.
– De-energize the drive.
– Secure the drive against unintended restart.

4 Electrical Installation

Phone: [phone] - Fax: [phone] - Web: www.clrwtr.com - Email: [e-mail]

This chapter illustrates the wiring of the following connections:

• Main terminals

• Relay terminals

• Motor encoder X13

• Application connection X14

The wiring of the main terminals and the application con nection depends o n the operat­ing mode of the drive. The drive offers the following operating modes:

• Keypad mode

• Terminal mode

• External control mode

• SEW controller mode

• Operation via gateway

Electrical Installation

4

Proper functioning requires wiring according to the respective operating mode. The
wiring options are therefore described in different sub-ch apters.

We strongly recommend to perform a simple startup first as this chapter refers to the
respective sub-chapter regarding the wiring according to the selected operating mode.

The connection X13 for the motor encoder and the r elay terminals are wired in the same
way for all operating modes. This is why the wiring is only described once for those two
connections.
