Location Considerations
This product is intended for installation in a “closed electrical operating area” or in
an enclosed industrial control cabinet. Consider these requirements when
selecting the mounting location:
Adequate ventilation for cooling
Space for servicing and repair
Protection from direct exposure to water or to a condensation-prone
environment
Protection from high-voltage or high-current devices, or devices which
produce electromagnetic interference (segregate the unit and wiring by at
least 15 cm (6 inches).
Avoidance of vibration
Selection of a location that will provide an operating ambient air temperature
range of
–40 to +70 °C (–40 to +158 °F) at the control
The control must NOT be mounted on the engine.
Electrical Connections
All inputs and outputs are made through screwless spring-actuated terminal
blocks. Use ESD precautions noted above when installing the wiring to prevent
damage due to ESD.
The spring clamp can be actuated by using a standard 2.5 mm or 3/32 inch flat
bladed screwdriver. The terminal blocks accept wires from 0.08
–4 mm²
(27
–12 AWG). Two 18 AWG or three 20 AWG wires can be easily installed in
each terminal. Wires for the fixed mounted power terminals should be stripped
5
–6 mm (0.22 inch) long.
Do not tin (solder) the wires that terminate at the terminal blocks. The
spring-loaded terminal blocks are designed to flatten stranded wire,
and if those strands are tinned together, the connection loses
surface area and is degraded.
Due to the hazardous location listings associated with this product,
proper wire type and wiring practices are critical to operation.
Do not connect any cable grounds to “instrument ground”, “control
ground”, or any non-earth ground system. Make all required
electrical connections based on the wiring diagrams (Figures
1-2a/b/c).
Cabling and installation wiring can affect the Electromagnetic Compatibility
(EMC) of the device, its ability to operate in an environment without being
interfered with, or interfering with other devices. Often other controls are installed
in the same enclosure, too. To address EMC concerns, it is recommended that
all low-current wires be separated from all high-current wire and similarly for
high-voltage and low-voltage wiring. For example, relay contact wiring and
electric motor drive or ignition system wiring should be at least 30 cm (12 inches)
from any 2301E wiring. And for example, analog inputs/output wiring should be
separated from power wiring by at least 15 cm (6 inches).
