Introduction
The 1394 fan kit is designed to provide additional cooling for the system
module. The fan is attached on top of the system module chassis
exterior and wired to 24V dc. You may need a volt meter and small
flathead screw driver to install the fan.
ATTENTION
To avoid shock hazard or personal injury, assure that
all power is removed from the system module before
proceeding. This system may have multiple sources of
power. More than one disconnect switch may be
required to de-energize the system.

Installing the 1394 Fan Kit
To install the 1394 fan kit:
1. Remove all input power to the drive. Allow five minutes for the DC
bus to completely discharge before proceeding.
ATTENTION
This product contains stored energy devices. To
avoid hazard of electrical shock, verify that all
voltage on capacitors has been discharged before
attempting to service, repair, or remove this unit.
You should only attempt the procedures in this
document if you are qualified to do so and are
familiar with solid-state control equipment and
the safety procedures in publication NFPA 70E.
2. Position fan kit over the system module vent slots by aligning the
bracket flush with the panel (refer to Figure 1).

IMPORTANT
Verify the fan kit kW rating matches the system
module kW rating. Mismatched fan kits will not
align properly with the vent slots.
3. Press fan kit downward, with bracket tabs inserted between vent
slots, until snap-locks click into place (refer to Figure 2).

ATTENTION
To avoid equipment damage, do not route the
fan wiring under the bracket. Keep fan wiring out
of the way while pressing fan and bracket down
onto the system module.
4. Verify the fan wiring is not routed under the fan and bracket.

Wiring the 1394 Fan Kit
The 1394 fan kit accepts only 24V dc, which can be supplied from the
system module 24V dc (logic) power supply or separate 24V dc supply.
IMPORTANT
The 1394 fan kit accepts only 24V dc (within a range
of 18.75 - 31.25V dc, 50/60 Hz). If your system
module logic power supply is 24V ac, then a
separate (customer-supplied) 24V dc must be used.
To wire the 1394 fan kit:
1. Route fan kit wires down along the side of the system module and
over to where the 24V dc power supply connections are made (refer
to figures 3 and 4 for the location of the 1394 connector locations).

2. Label and remove the 24V dc logic power wiring from the system
module.
3. Determine the positive 24V dc supply wire and align the red wire
from the fan kit to the +24V side.
4. Determine the negative 24V dc supply wire and align the black wire
from the fan kit to the -24V side.
IMPORTANT
The desired direction of air flow is upward. If fan
is wired backwards, air flow will be downward.
5. Insert and tighten the 24V dc supply wires (and fan wires) as
described in the table below (system module polarity is not
specified).

6. Gently pull on each wire to make sure it does not come out of its
terminal. Re-insert and tighten any loose wires.
7. Restore input power and verify drive operation.
