Table 4.3 Terminal Description

Additional terminals:

•

2 form C relay outputs. Location of the outputs

depends on frequency converter configuration.

•

Terminals located on built-in optional equipment.

See the manual provided with the equipment

option.

4.8.2

Wiring to Control Terminals

Control terminal connectors can be unplugged from the

frequency converter for ease of installation, as shown in

Illustration 4.10.

NOTICE

Keep control wires as short as possible and separate

from high power cables to minimise interference.

1. Open the contact by inserting a small screw

driver into the slot above the contact and push

the screw driver slightly upwards.
