•
The device does not contain any service components. Internal fuses
only trigger if there is a fault in the device. If the device is not
functioning correctly, or if it is damaged, switch off the voltage supply
and contact TC communications customer service.
•
Only switch on the supply voltage to the device if the housing is closed,
the terminal blocks are wired up correctly and the terminal blocks are
connected to the correct type of voltage supply.
B.3.0.2
Grounding
All TC Communications products are fully grounded and are in compliance
accordance with all regulations and
B.3.0.3
Housing
Only technicians authorized by TC Communications are permitted to open
the housing and break the seal.
•
Ensure that the electrical installation meets local or nationally applicable
safety regulations.
•
Never insert pointed objects (thin screwdrivers, wires, etc.) into the
inside of the ventilation holes in the side of the housing! Failure to
observe this point may result in injuries caused by electric shocks.
B.4
Environment
"Industrial Hardened" and "Industrial Ethernet" describe communications
products designed to operate in industrial process control environments or
geographical locations where harsh conditions are common.
To meet this level of durability, "Industrial" grade (synonyms for "industrial"
commonly include "rugged," "outdoor," "hardened," and "substation
hardened") TC's communications products are manufactured with special
components, connectors and circuitry. This ensures reliable operation in the
event of wide temperature swings, electromagnetic interference (EMI), radio
interference, vibrations, or moisture and humidity fluctuations. Conformal
coating is optional.
TC Communications Industrial Grade products are designed to exceed
pertinent industry specifications. For example, communications equipment
used in power substations are subject to extremes of temperature and
humidity, as well as electrical transients from high voltage switching.
These environmental conditions are described in industrial standard
specifications IEC 61850-3 and IEEE 1613 for networking devices. Similarly,
equipment used for traffic control applications are required to withstand
roadside vibration in addition to high/low heat and humidity. Testing
standards pertinent to traffic control are described in the environmental
requirements of the NEMA TS-2 standard.
