WARNING! High voltage!
Any contact with electric components , even after the
unit has been switched off, can cause serious injury or
death. Wait at least 4 minutes after switching off the unit,
until the current dissipates.
Grounding
Note the fan speed inverter has a high leakage current.
Be sure to ground the unit and take this into account
when installing the differiential protection device.
Differential protection should be suited for industrial
machinery with current leak which can be higher than
100 mA (several motors and frequency drives).

right side of the control panel. The wiring is passed
(A) 16 (2kW),25 (4kW)
through these conduits and connected to the disconnect
switch. To provide proper phasing of 3-phase input,
make connections as shown in field wiring diagrams and
as stated on the WARNING label in the starter panel. For
additional information on proper phasing, refer to "Unit
Voltage Phasing." Proper equipment ground must be
provided to each ground connection in the panel (one
for each customer supplied conductor per phase). High
voltage field-provided connections are made through
knockouts on the right side of the panel.
