Type EXAG
Installation Manual
This Installation Manual is valid only for encoder types EXAG.
For your safety please read this guide carefully.
Failure to follow the instructions in this guide will render ALL certifications INVALID.
1. Installation
Installation of the encoder must be completed by a skilled technician or engineer. Failure to comply with the instructions below
will render all certifications INVALID. The encoder may not be modified by the customer.
1. Insure that power is off.
2. Connect to earth prior to proceeding -
Observe precautions for handling ESD (ElectroStatic Discharge) sensitive devices.
Protective Earthing Method:
INTERNAL: The internal grounding terminal shall be used for the equipment grounding connection.
Earth connection can be provided by a RED ring terminal(s) (red cable shoe) screwed to the PCB inside the encoder
removable connection cap. Terminal(s) AWG size is 22-16 AWG.
EXTERNAL: The external terminal is for a supplementary bonding connection where local codes or authorities
permit or require.
Earth connection can be provided by YELLOW ring terminal (cable shoe) which is screwed to the chassis. Terminal
AWG size is 12-10.
See Product Specification for details on www.scancon.dk
3. Connect encoder Circuit Ground (GND).
See Product Specification for details on www.scancon.dk
4. When installing the Hollow Shaft encoder, check that the encoder fixing clamp is loose. Then slide
the encoder hollow bore over the motor shaft (or other device).
5. Align encoder spring coupling or torque arm mounting hole(s) with motor face plate hole(s). Insert
screws into mounting holes and tighten.
6. Tighten fixing clamp M3 screw (maximum 1.5 Nm (1.12 lbft) torque).
7. Remove the protective plastic insert(s) from the cable gland outlet(s). This must be done prior to final installation.
8. Use only EX d certified cable glands (or blind plug, if no cable is attached) which meet EN/IEC 60079-1
requirements for attaching cable to the encoder. Cable entry threads are min. M16x1,5; M20 x 1,5; M25 x 1,5;
½”NPT, ¾”NPT.
9. Use only shielded cable. Be aware of National Wiring Standards for ATEX environments. For ambient temperatures
below -10oC and above +60oC use field wiring suitable for minimum and maximum ambient temperatures.
10. Connect remaining Output wires to PLC. Then apply power (insure the Supply Voltage is correct!).
11. If used, safety screws in the Removable End Cap shall have a minimum yield stress of 450 MPa.
12. Precautions must be taken to avoid dust from forming layers on the encoder.

13. It is strongly recommended that the original packaging be used for any additional shipping or transport.
Caution/Warning:
1. DO NOT connect encoder when power is on.
2. DO NOT connect output wires to supply voltage.
3. WARNING: Do not open when an explosive atmosphere is present!
AVERTISSEMENT: Ne pas ouvrir en présence d'une atmosphère explosive!
4. Caution- Hot surface.
Attention - surface chaude.
5. DO NOT strike encoder with hammer or any other heavy object.
6. DO NOT tighten the Ex-proof cable gland while the encoder is attached to the shaft. Excessive torque may
result in damage to the encoder ball bearings.
7. WARNING: Open circuit before removing cover. Keepcover tight while circuits are alive!
8. WARNING: Potential electrostatic charging hazard - see instruction!
AVERTISSEMENT: Risque de formation d'un potential électrostatique - voir instructions!
To minimize the risk from electrostatic discharge - clean only with a damp cloth.
9. WARNING: A seal shall be installed within 50mm of the enclosure.
AVERTISSEMENT: Un scellement doit être installé à moins de 50 mm du boîtier.
10. WARNING : Temperatures at the branching point can reach 85°C. Selection of cable must be appropriate for
the ambient tempearture range in which the product is used !
AVERTISSEMENT: La Température au point de branchement peut monter jusqu'à 85 ° C. La sélection du câble et
presse-étoupe, doit être approprié, à la plage de température ambiante dans laquelle le produit est utilisé !
11. If encoder is mounted to electrical machinery with high current or high voltage on the shaft, precautions must
be taken for galvanic separation.
12. Maintenance is not necessary. Any required maintenance or repair is to be done only by the manufacturer.
13. Note: this equipment is suitable for use in Class I, Division 2, groups ABCD or Class II, Division 2, groups FG
or non-hazardous locations only!
14. Use only fasteners with a minimum yield stress of 450 Mpa.
Utilisez uniquement des fixations avec une limite d'élasticité minimale de 450 MPa.
15. Only suitably certified cable glands, fittings, and/or blind plugs may be used.
Seulement convenablement certifié presse-étoupes, raccords et / ou bouchons peuvent être utilisés.
