Power Connections; Control Connections - WEG WECM-AL80-85A2 Installation, Operation And Maintenance Manual

5.1. POWER CONNECTIONS

DANGER!
Connect the motor properly to the power supply by means of safe and permanent
contacts, always considering the data informed on the nameplate, such as rated
voltage, wiring diagram, etc.
For power cables, switching and protection devices dimensioning, consider the rated motor current,
the service factor, and the cable length, among others. For motors without terminal block, insulate
the motor terminal cables by using insulating materials that are compatible with the insulation class
informed on the nameplate. The minimum insulation distance between the non-insulated live parts
themselves and between live parts and the grounding must meet the applicable standards and
regulations for each country.
Input voltage selection (if available):
g
Interconnect the jumper leads to an 115V input voltage;
Keep the jumper leads disconnected to 208V or higher input voltage (according nameplate
indication);
Make the line, neutral and ground connections according nameplate indication;
g
If used, connect the optional external harmonic filter (passive PFC) in series to the line conduc-
g
tor, according to Item 6.6 - PASSIVE POWER FACTOR CORRECTION (PFC) (OPTIONAL).
WEG declares that the WECM / Emerald eZA motor line is intended to be used as a part of an
end-product and thus is not an independently used machine. All cables of this product need to be
internally installed into the enclosure of the final product.
DANGER!
Make sure the jumper terminals in power cable are insulated to avoid electrical
g
shock.
SHOCK RISK! Do not touch the jumper terminals after the product is fed.
g
Always connect the equipment to the ground protection (PE).
g
ATTENTION!
The power supply that feeds the inverter shall have a solid grounded neutral.
g

5.2. CONTROL CONNECTIONS

Make the control connections according nameplate indication.
g
ATTENTION!
Make sure that all unused conductors in control cable are insulated to avoid product
damage.
