WARNING
Electrical Consideration / Precautions
The controller is considered "rack and panel mounted equipment" per EN61010-1, Safety
Requirements for Electrical Equipment for Measurement, Control and Laboratory Use, Part 1:
General Requirements. Conformity with 72/23/EEC Low Voltage Directive, requires the user to
provide adequate protection against a shock hazard. The user shall install this controller in an
enclosure that prevents OPERATOR access to the rear terminals.
Failure to comply with these instructions could result in death or serious injury.
CAUTION
Applying 85-264Vac to a controller rated for 15-50Vdc will severely damage the controller
and is a fire and smoke hazard.
Failure to comply with these instructions may result in product damage.
CAUTION
Wiring Requirements
Shielded twisted pair cable is required for all Analog I/O, Process Variable, RTD, Thermocouple, dc
millivolt, low level signal, mA, Digital Output, and computer interface circuits.
Failure to comply with these instructions may result in product damage.
CAUTION
Line Voltage Wiring
This controller is suitable for connection to 90-240 Vac, 50/60 Hz or 15-50 Vdc, power supply
mains. It is the user responsibility to provide the following
90-240 Vac - a switch, fuse (1/2A, 250V) or a circuit breaker.
15-50 Vdc – a switch, fuse (1A, 125A) or a circuit breaker
Fuse types – North America non-time delay, Europe – Type F, quick acting fuse(s).
The above items should be installed together with DC1000 for the products electrical protection.
The switch or circuit-breaker should be located close to the controller, within easy reach of the
operator. The switch or circuit-breaker should be marked as the disconnecting device for the
controller.
When applying power to multiple instruments, make sure that sufficient current is supplied.
Otherwise, the instruments may not start up normally due to the voltage drop caused by the in-
rush current.
Failure to comply with these instructions may result in product damage.
