Installation and Startup of UA 300 D
4.1
Connection and safety notes
S
This manual is an integral part of the equipment. It should be kept close to the equipment for ready reference
whenever needed.
S
For safety reasons, the equipment must not be used for any application other than described in the manual
i.e. only for the intended purpose.
S
Before using the equipment, always check that its limits are suitable for the intended application.
S
Check that the electric power supply is correct for the equipment before connecting it to power.
S
If required, a reverse voltage protection must be installed by the customer, e.g. by means of a coding of the
plug.
S
Specified ambient conditions (e.g. humidity and temperature limits) must be observed and complied with in
order to avoid malfunctioning (see Section 9 − Specifications).
S
Check correct wiring of the connections before switching on power to the equipment.
S
Never operate the equipment without its casing. Before opening the casing the equipment must be switched to
zero potential.
Beware of external voltage at the digital inputs and outputs!
S
Contact the supplier in any malfunction or in case of doubt.
S
Note and observe maximum load on relay contacts (see Section 9 − Specifications).
S
Note that all leads running to and from the UA 300 D − especially those of the CAN bus − must be shielded and
installed sufficiently clear of other leads carrying live power. Doing so will avoid faulty measurements and will
protect the equipment from external interference via the analog inputs.
Parallel connection of RC elements is recommended for applications in an industrial environment.
For further details please refer to the manual titled Introduction, General Safety and Connection No-
tes.
1. In the interests of fire prevention, allowance should be made at the time of planning the system for
a suitable shutdown device designed to operate in the event of excessive temperature on the defrost
heater (high−temperature cutout).
2. Experience shows that transmission of alarms is often not operational (telephone line not yet in-
stalled, etc.) at the time of commissioning the system. In such instances it is urgently recommended
to monitor the controller with a CI 3000 Store Computer or AL 300 Operator Terminal via the CAN
bus and allow transmission of alarms via a mobile telephone system using a GSM modem for exam-
ple. In stand−alone operation or as an alternative to monitoring by Store Computer/Operator Termi-
nal, an alarm contact provided on the controller can be used to transmit alarms via telephone line.
