5 Installation Procedure

◆

Installing the Option

Refer to the instructions below to install the option.

Shut off power to the unit, wait the appropriate amount of time for voltage to

dissipate, then remove the digital operator (D), front cover (C), and terminal cover

(E). Cover removal varies depending on unit size. Refer to the instruction manual

packaged with the unit for directions on removing the covers.

DANGER! Electrical Shock Hazard. Disconnect all power to the unit and wait at least the amount of time

specified on the unit front cover safety label. After all indicators are off, measure the DC bus voltage to

confirm safe level, and check for unsafe voltages before servicing to prevent electric shock. The internal

capacitor remains charged even after the power supply is turned off.

NOTICE: Damage to Equipment. Observe proper electrostatic discharge procedures (ESD) when handling

the option, unit, and circuit boards. Failure to comply may result in ESD damage to circuitry.
