4.2.1 Temperature alarms
The maximum temperature levels are as follows:
o A warning will be raised when the internal temperature reaches higher than 68°C
o An alarm with output muting will trigger after internal temperatures reach higher
than 71°C
In both cases, the normal status conditions return when the temperature falls below
67°C.
4.2.2 Cooling methods
Specific care must be taken concerning the cooling system. The following figure shows
air flow due to internal fans. When the unit is integrated in an equipment cabinet,
sufficient space must be left on the right and left side of the unit to allow sufficient air
flow.
4.3 Wiring and Powering on
Once fixed in a location, the exciter can be wired depending on its configuration.
When powered ON, the exciter is fully operational after a few seconds. Please refer to
section 3.3 for a front panel LED diagnostic.
To simply control and monitor the EXACT, any web browser can be used with an IP
connection between the exciter and the PC. The default IP address is 192.168.0.209
on IP port #1. The control port #1 IP configuration can be retrieved/modified using
the front panel menu.

Notes: The power supply connector must remain available to easily
disconnect the equipment in case of emergency.
