Electrical Considerations
Line voltage wiring
This 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 2014/35/EU, the Low Voltage
Directive requires the user to provide adequate protection against a
shock hazard. The user shall install this controller in an enclosure
that limits OPERATOR access to the rear terminals.
Mains Power Supply
This equipment is suitable for connection to 100 to 240 Vac 50/60
Hz, power supply mains. It is the user’s responsibility to provide a
switch and non-time delay (North America), quick-acting, high
breaking capacity, Type F (Europe), 1/2 A, 250V UL listed fuse(s), or 1
A UL listed circuit-breaker for 100-240 Vac applications, as part of
the installation. The switch or circuit-breaker shall be located in close
proximity to the controller, within easy reach of the OPERATOR. The
switch or circuit-breaker shall be marked as the disconnecting device
for the controller.
CAUTION: Applying 100-240 Vac to an instrument rated for 24
Vac/dc will severely damage the instrument and is a fire and
smoke hazard.
NOTE: Tested with UL listed (DIVQ breaker - not current
limiting), voltage rating 277 Vac, current rating 1 A.
ATTENTION: It is recommended to set up an uninterrupted
power supply to avoid fluctuations on the device power line, as
such fluctuations may cause device availability issues.
When applying power to multiple instruments, make certain that
sufficient current is supplied. Otherwise, the instruments may not
start up normally due to the voltage drop caused by the in-rush
current.
