ATTENTION: To avoid an electric shock hazard, ensure that

all power to the drive has been removed before performing the

following.

ATTENTION: To avoid an electric shock hazard, verify that

the voltage on the bus capacitors has discharged before

performing any work on the drive. Measure the DC bus voltage

at the DC+ & DC- terminals. The voltage must be zero.

ATTENTION: HOT surfaces can cause severe burns. Do not

touch the heatsink surface during operation of the drive. After

disconnecting power allow time for cooling.

ATTENTION: Hazard of permanent eye damage exists when

using optical transmission equipment. This product emits intense

light and invisible radiation. Do not look into fiber-optic ports or

fiber-optic cable connectors.

ATTENTION: This drive contains ESD (Electrostatic

Discharge) sensitive parts and assemblies. Static control

precautions are required when installing, testing, servicing or

repairing this assembly. Component damage may result if ESD

control procedures are not followed. If you are not familiar with

static control procedures, reference A-B publication 8000-4.5.2,

“Guarding Against Electrostatic Damage” or any other

applicable ESD protection handbook.

PowerFlex® 700H/S Frame 9 Main Fan and Isolation Transformer Assembly Replacement Step 1: Opening the Drive 1. Remove power from the drive. 2. Check for zero volts between DC+ and DC-. 3. Remove the Connection cover. Figure 1 L1 L2 L3 L1 L2 L3 U/T1 V/T2 W/T3 U/T1 V/T2 W/T3 (8 Screws) Step 2: Disconnecting and Removing the Main Fan Assembly Important: Before removing connections and wires, mark the connections and wires to avoid incorrect wiring during assembly. 1.

Remove the four screws from bottom of the main fan frame (see Figure 4 below). The fan plate should now easily slide down. If it does not, loosen the front screws another turn and attempt again. Continue loosening the screws until the fan plate slides easily from the drive. Note: The old main fan long support bracket will be discarded.
