Special Conditions for Safe Use
This Equipment is Suitable for use in Class I, Division 2, Groups A, B, C, D or Non Hazardous Locations
Only.
This equipment is suitable for use in European Zone 2, Group IIC environments or Non Hazardous
Locations Only.
Wiring must be in accordance with North American Class I, Division 2, or European Zone 2, Category 3
wiring methods as applicable, and in accordance with the authority having jurisdiction.
A fixed wiring installation is required and a switch or circuit breaker shall be included in the building
installation that is in close proximity to the equipment and within easy reach of the operator and that is
clearly marked as the disconnecting device for the equipment. The switch or circuit breaker shall not
interrupt the protective earth conductor.
Protective Earth Grounding is required by the input PE terminal.
Field wiring must be rated at least 85 °C for operating ambient temperatures expected to exceed 50 °C.
For European ATEX compliance on panel mount models, this equipment must be installed in an area
providing adequate protection against the entry of dust or water. A minimum ingress protection rating of
IP54 is required for the enclosure.
Personnel must discharge their electrostatic build up to the cabinet ground point or use an ESD strap
prior to touching the ProTech interior surfaces if the engine/turbine is operational. The unit is designed to
have one of three modules be removed during operation; however ESD to the remaining operational
modules may cause signal deviations. Signal deviations due to direct ESD may be large enough to result
in the operational module to trip, shutting down the engine since two modules are in a tripped mode.
Signal deviations were noted when ESD testing was done to the Speed pins, the IRIG-B pins, Service
Port pins, and RS-232/RS-485 MODBUS communications port pins.
Do not remove module unless module is de-energized and all wire
connections have been disconnected
The Service Port (RS-232 communication) is not designed to remain connected during operation except
at servicing and programming intervals. It should not have a cable connected to it other than during
programming and servicing.
This device contains a single cell primary battery. This battery is not to be charged and is not customer
replaceable.
Control is suitable for installation in pollution degree 2 environments.
Measurement inputs are classified as permanently connected IEC
measurement Category I and are designed to safely withstand
occasional transient overvoltages up to 1260 Vpk. To avoid the
danger of electric shock, do not use these inputs to make
measurements within measurement categories II, III, or IV.
Explosion Hazard—Do not connect or disconnect while circuit is live
unless area is known to be non-hazardous.
Substitution of components may impair suitability for Class I,
Division 2 or Zone 2 applications.
