Wiring Diagram
WIRE INSTALLATION
- Insert screwdriver and push wire locking mechanism open
- Insert wire
- Remove screwdriver
- Due to possible significant interference in industrial installations, appropriate measures assuring correct operation of the unit must be applied.
- The unit is not equipped with an internal fuse or power supply circuit breaker.
- For this reason, an external time-delay cut-out fuse with a small nominal current value must be used (recommended bipolar, max. 2A) and a power supply circuit breaker located near the unit.
Connections
Power Supply & Relay Connection
Contacts of relay outputs are not equipped with spark suppressors. When using the relay outputs for switching of inductive loads (coils, contactors, power relays, electromagnets, motors etc.) it is required to use additional suppression circuit (typically capacitor 47nF/ min. 250VAC in series with 100R/5W resistor), connected in parallel to relay terminals or (better) directly on the load.
