Safety Instructions
● W en working wit t e CAN-T-Connector follow t e instructions below and read t e manual carefully
to protect yourself from injury and t e CAN-T-Connector from damage.
● T e device is a built-in component. It is essential to ensure t at t e device is mounted in a way t at
cannot lead to endangering or injury of persons or damage to objects.
● Do not use damaged or defective cables to connect t e CAN-T-Connector and follow t e CAN wiring
ints in c apter: "Correct Wiring of Electrically Isolated CAN Networks".
● In case of damages to t e device, w ic mig t affect safety, appropriate and immediate measures
must be taken, t at exclude an endangerment of persons and domestic animals and property.
● Current circuits w ic are connected to t e device ave to be sufficiently protected against
azardous voltage (SELV according to EN 60950-1).
● T e CAN-T-Connector may only be driven by power supply current circuits, t at are contact
protected.
A power supply, t at provides a safety extra-low voltage (SELV) according to EN 60950-1, complies
wit t is conditions.
● T e device as to be securely installed before commissioning.
● Protect t e CAN-T-Connector from dust, moisture and steam.
● Protect t e CAN-T-Connector from s ocks and vibrations.
● T e CAN-T-Connector may become warm during normal use. Always allow adequate ventilation
around t e CAN-T-Connector and use care w en andling.
● Do not operate t e CAN-T-Connector adjacent to eat sources and do not expose it to unnecessary
t ermal radiation.
Qualified Personnel
T is documentation is directed exclusively towards personnel qualified in control and automation
engineering. T e installation and commissioning of t e product may only be carried out by qualified
personnel, w ic is aut orized to put devices, systems and electric circuits into operation according to
t e applicable national standards of safety engineering.
Intended Use
T e intended use of t e CAN-T-Connector is t e connection of modules to a bus system e.g. CAN.
T e guarantee given by esd does not cover damages w ic result from improper use, usage not in
accordance wit regulations or disregard of safety instructions and warnings.
● T e CAN-T-Connector is intended for indoor use only.
● T e operation of t e CAN-T-Connector in azardous areas, or areas exposed to potentially explosive
materials is not permitted.
● T e operation of t e CAN-T-Connector for medical purposes is pro ibited.
Service Note
T e CAN-T-Connector does not contain any parts t at require maintenance by t e user. T e CAN-T-
Connector does not require any manual configuration of t e ardware. Unaut orized intervention in t e
device voids warranty claims.
Disposal
Devices w ic ave become defective in t e long run ave to be disposed in an appropriate way or
ave to be returned to t e manufacturer for proper disposal. Please, make a contribution to
environmental protection.

In t e CAN-T-Connector t e metal s ells of t e DSUB connectors are not connected. T us, t e
metal s ells are not connected t roug t e CAN-T-Connector, see Figure 3.
2.1.2 Usage in Lig t Industrial Environment (Single Twisted Pair Cable)
In t e standard esd CAN cables (Single Twisted Pair Cable, 2-wire + S ied) for lig t industrial
environment applications (see Figure 4), t e cable s ield (braided s ield) is used as signal
CAN_GND, but t is signal is not connected to t e metal s ell of t e DSUB9 connectors.
Instead, t e CAN_GND signal is connected to Pin 3. T erefore t e CAN-T-Connector is compatible
wit t e standard esd CAN cables.

2.1.3 Usage in Heavy Industrial Environment (Double Twisted Pair
Cable)
W en using t e esd’s CAN-T-Connector type C.1311.03 wit single s ielded double twisted pair
cables in eavy industrial environment applications, please note t at t e s ield potential of t e
conductive DSUB ousing is not looped t roug t is CAN-T-connector type (see also c apter
“Device Cabling” page 15).
T us, t e braided s ields of t e CAN cables ave to be connected to an external s ield
connection, for example via clamp straps (see Figure 5), to connect t e s ield potentials of t e
cables.
