3.2.1. Control Wires

Connect the wires as described in the Operat-
ing Instruction for the frequency converter.
Remember to connect the shields in a proper
way to ensure optimum electrical immunity.
Control cable routing
Tie down all control wires to the designated
control cable routing.
Fieldbus connection
Connections are made to the relevant options
at the control card. For details see the relevant
fieldbus instruction. The cable must be placed
to the left inside the frequency converter and
tied down together with other control wires.
In the IP 00 (Chassis) and IP 21 (NEMA 1)
units it is also possible to connect the fieldbus
from the top of the unit as shown on the pic-
ture below. On the IP 21 (NEMA 1) unit a
cover plate must be removed.
Installation of 24 Volt external DC Supply
Torque: 0.5 - 0.6 Nm (5 in-lbs)
Screw size: M3
24 V external DC supply can be used as low-voltage supply to the control card and any option
cards installed. This enables full operation of the LCP (incl. parameter setting) without connection
to mains. Please note that a warning of low voltage will be given when 24 V DC has been con-
nected; however, there will be no tripping. If 24 V external DC supply is connected or switched
on at the same time as the mains supply, a time of min. 200 msec. must be set in parameter 120
Start delay.
