1204 Terminator (Class 1, Division 2)

(Catalog Number 1204-TFA1, 1204-TFB2)

Where this Option is Used The 1204 Terminator Option can be installed in most adjustable

frequency AC drive applications to increase protection of the AC
motor. The option is designed to be used with Allen-Bradley
Adjustable frequency AC drives. When installed at the motor
terminals, the terminator can reduce potentially destructive reflected
wave spikes that can occur with long motor leads.

What this Option Contains The Terminator Option contains the terminator device with an

2

attached 3 meter (10 feet) standard 4 wire 3mm
connection cable.

(12 gauge)

What these Instructions Contain

These instructions contain the information you need to properly
install the Terminator Option. Recommended mounting, connecting,
and grounding procedures are included. Major topics and page

Determining the Maximum Cable Length for Your System

Use the following tables to determine the maximum cable length for
your system.

The values shown are for nominal input voltage and a drive carrier
frequency of 2 kHz. If you plan to operate your system at carrier
frequencies above 2 kHz, refer to the heat dissipation table on page 3.
If you plan to operate your system above the levels listed in the heat
dissipation table, consult the factory.

If you are running at high-line conditions (nominal line + 10%),
multiply the values by 0.85.

1204 Terminator (Class 1, Division 2) 7

Installation Installation of the 1204 Terminator must be in accordance with

Class I, Division 2 wiring methods as defined in Article 501-4(b) of
the National Electrical Code, NFPA 70 for installations within the
United States, or as specified in Section 18-152 of the Canadian
Electrical Code for installation within Canada.

WARNING: EXPLOSION HAZARD

!

• Substitution of components may impair suitability for

Class I, Division 2.

• When in hazardous locations, turn off power before

replacing or wiring modules.

• Do not disconnect equipment unless power has been

switched off or the area is known to be nonhazardous.

To install the terminator, follow these steps:

1. Remove all power connected to the system.

ATTENTION: Electric shock can cause injury or

!

death. Remove all power before working with this
product. Verify that the voltage on the bus capacitors
has discharged. Measure the DC bus voltage at the +
and – terminals of TB1. The voltage must be zero.

ATTENTION: The terminator surfaces may be hot
enough to cause serious burns. You should take this into
consideration when deciding where to mount your
terminator.

2. Mount the terminator on a metal surface.

to cause serious burns. If your system consistently runs at
line voltages above nominal, you should place a shroud
around the terminator to prevent accidental exposure.

4. If your system consistently runs at line voltages above nominal

and you are mounting the terminator in a high-traffic area where
the potential for contact is high, you should place a shroud of
expanded metal or mesh screen around the terminator. The shroud
should not restrict air flow to the terminator, nor should it be
closer than 152.4 mm (6 in.) to the terminator at any point.

corresponding three-phase motor leads/terminals.

6. Attach the green cable conductor to the motor ground that is

connected directly to the drive PE terminal.

Drive Programming If the default PWM frequency is greater than the maximum drive

carrier frequency listed on page 3, you must re-program the drive to a
value that is less than or equal to the maximum drive carrier
frequency.

Grounding Follow the recommended grounding practices provided in your drive

User Manual. The following illustration shows an example of the
system grounding practices.

Ground per

Important: If you cannot connect the terminator directly to the motor

mounted junction box, an auxiliary junction box can be
used. However, the terminator-to-motor connection length
should be no more than 6 meters (20 feet).
If installed in hazardous location, an auxiliary junction box
rated Class 1, Division 2 must be used.

ATTENTION: The National Codes and standards (NEC,

!

VDE, BSI, etc.) and local codes outline provisions for safely
installing electrical equipment. Installation must comply
with specifications regarding wire types, conductor sizes,
branch circuit protection, and disconnect devices. Failure
to do so may result in personal injury and/or equipment
damage.

You can power up the system once proper installation, drive
programming, and grounding is completed.

10 1204 Terminator (Class 1, Division 2)

Maintenance The terminator does not require routine maintenance. However, you

should periodically remove dust to allow for maximum cooling
efficiency.

ATTENTION: Electric shock can cause injury or death.

!

!

Remove all power before touching the terminator.

ATTENTION: The terminator surfaces may be hot enough
to cause serious burns. Allow the terminator time to cool
down before touching any surface.
