3 - Inverter installation and connections
Read the WEGPM User’s Manual which is supplied with the inverter before installing, powering up or
operating the inverter.
F
Note!
g
Install the inverter according to Chapter 3 - Installation and connections of the Manual.
g
Prepare the drive and power up the inverter according to Chapter 4 - configuration of the inverter of the
Manual.
Note:
1.When installing DC reactor, make sure to dismantle the short connector between terminal P1 and (+).
2.NPN or PNP transistor signal can be selected as input of multi-function input terminal (X1~X7/PUL). Inverter built-in power supply
(+24V terminal) or external power supply (PLC terminal) can be chosen as bias voltage. Factory setting ‘+24V’ short connect with ‘PLC’.
3. Analog monitor output is the special output for meters such as frequency meter, current meter and voltage meter. It can’t be used for
control operations such as feedback control.
4. As there are multi pulse styles, please refer to the line connect mode description details.
