 Prior to Installing the Option
Prior to installing the option, wire the drive, make necessary connections to the drive terminals, and verify that the drive
functions normally without the option installed. Refer to the Quick Start Guide packaged with the drive for information
on wiring and connecting the drive.
 Installing the Option
Refer to the instructions below to install the option.
DANGER! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on. Failure to comply could result in death
or serious injury. Before installing the option, disconnect all power to the drive. The internal capacitor remains charged even after the
power supply is turned off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent electric
shock, wait at least five minutes after all indicators are off and measure the DC bus voltage level to confirm safe level.
1. Shut off power to the drive, wait at least five minutes after confirming the DC bus voltage is safe, then loosen the
screw that fastens the front cover in place and remove the front cover. This drive front cover will be replaced by
the option cover. Cover removal varies depending on drive size.
NOTICE: Damage to Equipment. Observe proper electrostatic discharge procedures (ESD) when handling the option, drive, and
circuit boards. Failure to comply may result in ESD damage to circuitry.

Do not use unshielded cable for control wiring.
Failure to comply may cause electrical interference resulting in poor system performance.
Use shielded twisted-pair wires and ground the shield to the ground terminal of the drive.
Properly connect all pins and connectors.
Failure to comply may prevent proper operation and possibly damage equipment.
Check wiring to ensure that all connections are correct after installing the option and connecting any other
devices.
Failure to comply may result in damage to the option.
