4.1 Safety Instructions
See chapter Safety for general safety instructions.
W A R N I N G
INDUCED VOLTAGE
Induced voltage from output motor cables that run together can charge equipment capacitors, even with the equipment turned
off and locked out/tagged out. Failure to run output motor cables separately or to use shielded cables could result in death or
serious injury.
Run output motor cables separately or use shielded cables.
-
Simultaneously lock out/tag out all the drives.
-
W A R N I N G
ELECTRICAL SHOCK AND FIRE HAZARD – RCD COMPLIANCE
The drive can cause a DC fault current in the PE conductor. Failure to use a Type B residual current-operated protective device
(RCD) can lead to the RCD not providing the intended protection and therefore can result in death, fire, or other serious hazard.
When an RCD is used for protection against electrical shock or against fire, only a Type B device is allowed on the supply side.
-
Overcurrent protection
•
Extra protective equipment, such as short-circuit protection or motor thermal protection between drive and motor, is required
for applications with multiple motors.
•
Input fusing is required to provide short-circuit and overcurrent protection. If not factory-supplied, the installer must provide
fuses. See maximum fuse ratings in chapter Fuses and Circuit Breakers.
Wire type and ratings
All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements.
•
Power connection wire recommendation: Minimum 75 °C (167 °F) rated copper wire. See
•

4.9.2 Wiring to Control Terminals
Control terminal connectors can be unplugged from the drive for ease of installation, as shown in 4.9.1 Control Terminal Types.
For details about safety functions wiring, refer to chapter 6 Safety Functions. See 9.5 Cable Specifications for control terminal cable
sizes and chapter Application Examples for typical control cable connections.
N O T I C E
Keep control cables as short as possible and separate them from high-power cables to minimize interference.
4.9.2.1 Wiring
Procedure
1.
Loosen the screws for the terminals.
2.
Insert sleeved control cables into the slots.
3.
Fasten the screws for the terminals.
4.
Ensure that the contact is firmly established and not loose. Loose control wiring can be the source of equipment faults or
less than optimal operation.
4.9.3 Enabling Motor Operation (Terminal 27)
A jumper wire is required between terminal 12 (or 13) and terminal 27 for the drive to operate when using factory default programming values.
•
Digital input terminal 27 is designed to receive 24 V DC external interlock command.
•
When no interlock device is used, wire a jumper between control terminal 12 (recommended) or 13 to terminal 27. The jumper
provides an internal 24 V signal on terminal 27.
•
Only for GLCP: When the status line at the bottom of the LCP reads AUTO REMOTE COAST, it indicates that the unit is ready to
operate but is missing an input signal on terminal 27.
N O T I C E
UNABLE TO START
The drive cannot operate without a signal on terminal 27, unless terminal 27 is reprogrammed.
