Installation instructions
Safety and operating instructions
Product manual and product file (ETS 5 application) can be downloaded from the
Elsner Elektronik website on www.elsner-elektronik.de in the “Service” menu.
Installation, testing, operational start-up and troubleshooting should only be
performed by an authorised electrician.
DANGER!
Risk to life from live voltage (mains voltage)!
There are unprotected live components inside the device.
- Inspect the device for damage before installation. Only put undamaged devices into operation.
- Comply with the locally applicable directives, regulations and provisions for electrical installation.
- Immediately take the device or system out of service and secure it against unintentional switchon if risk-free operation is no longer guaranteed.
Use the device exclusively for building automation and observe the operating
instructions. Improper use, modifications to the device or failure to observe
the operating instructions will invalidate any warranty or guarantee claims.
Operate the device only as a fixed-site installation, i.e. only in assembled
condition and after conclusion of all installation and operational start-up
tasks, and only in the surroundings designated for it.
Elsner Elektronik is not liable for any changes in norms and standards which
may occur after publication of these operating instructions.
Description
The intelligent Power Supply KNX PS640-IP 2U with extensive diagnostic and
alarm functionality powers one line of a KNX system with 30 V DC and has an
additional unchoked voltage output to provide auxiliary power. Both outputs
are overload-proof and short circuit protected. LEDs indicate the state of the
power supply and the KNX TP line.
The KNX TP line can be reset via object and via push-button press. For
diagnostics, input state, KNX bus voltage, output current, device temperature
and times of operation (total/since last startup) are monitored. Alarms inform
about measurement values leaving the normal working range or the configured
threshold range. Up to eight different alarms can be pre-defined.
KNX PS640-IP 2U is able to send info telegrams on request, periodically and
after certain events. Details (number/duration) on output failures like short
circuits, overloads and over-threshold events are accessible. Info telegrams
also inform on returning to normal working condition after device startup,
after a KNX bus restart and after a short circuit. Heartbeat telegrams
indicate proper functioning.
