3 – Setup
3.1 Prerequisites for Setup
Modules should be mounted on the mounting plate through the mounting holes provided
on the enclosure.
Modules must be mounted vertically! A minimum of 150mm clearance is
imperative
above and below to dissipate heat efficiently!
Do not drill additional mounting holes
on the device!
Modules should be grounded through the mounting holes. 50kVAr and 80kVAr
modules may also be grounded through connecting the ground cable to the auxiliary power
supply connector.
Electrical connections should follow the wiring diagrams provided in Figures 3.3-3.6 in the
Wiring Diagrams section.
“Superfast” electronic branch fuses must be used to protect the
thyristor modules!
12kVAr and 25kVAr modules do not require an auxiliary voltage connection. These modules
are powered internally. The 50kVAr and 80kVAr modules are equipped with a fan and are
designed for forced cooling.
Therefore, 50kVAr and 80kVAr modules require an auxiliary voltage
(220V 50Hz) supply to power internal circuits and the cooling fan!
Modules can be instantaneously activated through a power factor correction relay, or any
other compatible system, by applying a 10-24VDC trigger signal. Internal circuits are galvanically
isolated from the trigger signal.
Thyristor modules are equipped with an external thermostat terminal. If a detuned filter
reactor is used in the system, the user may attach its thermostat to the external thermostat
terminal on the module. This allows the module to protect the detuned filter reactor from
overheating.
If this external thermostat connection is not used, user must short the thermostat
connection terminals for the system to function properly!
