Scancon EXAG series Installation Manual

EXAG-Hollow Shaft
Installation guide
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
3. Connect encoder Circuit Ground (GND).
See Product Specification for details on
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
o
below -10 C and above +60
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.
