IMPORTANT

Mounting Requirements

The following requirements apply when preparing to mount your line interface
module:

ATTENTION: Plan the installation of your system so that you can perform all cutting,
drilling, tapping, and welding with the system removed from the enclosure. Because
the system is of the open type construction, be careful to keep any metal debris from
falling into it. Metal debris or other foreign matter can become lodged in the circuitry,
which can result in damage to components.

• The line interface module must be enclosed in a grounded conductive
enclosure offering protection as defined in standard EN 60529 (IEC 529)
to IP55 such that they are not accessible to an operator or unskilled person,

to comply with UL
these requirements providing protection to IP66.

• The panel you install inside the enclosure for mounting your system
components must be on a flat, rigid, vertical surface that won’t be subjected
to shock, vibration, moisture, oil mist, dust, or corrosive vapors.

• Observe the Environmental Specifications

• Maintain minimum clearances for proper airflow, easy module access, and

proper cable bend radius as shown in the figures on page 5

and CE requirements. A NEMA 4X enclosure exceeds

on page 55.

.

Mount the line interface module in an upright position as shown. Do not mount the
module on its side.

Establishing Noise Zones

Observe these guidelines when a 2094-ALxxS, 2094-BLxxS, or 2094-XL75S-Cx
line interface module is used in the system and mounted left of the drive with the
AC (EMC) line filter mounted above the module:

• The clean zone (C) is to the right and beneath the drive system (gray
wireway).

• The dirty zone (D) is to the left and above the drive system, and above and
below the line interface module (black wireway).

• The very dirty zone (VD) is from the filter output to drive. Shielded cable
is required on the EMC filter (LOAD side) and the braided shield
attached to the clamp (when provided).

• The sercos fiber-optic cables are immune to electrical noise.

Figure 3 - Establishing Noise Zones (EMC filter above the line interface module)

(1) If drive system I/O cable contains (dirty) relay wires, route cable with module I/O cable in dir ty wireway.
(2) When space does not permit the 150 mm (6.0 in.) segregation, use a grounded steel shield instead. For examples, see the System

Design for Control of Electrical Noise Reference Manual, publication GMC-RM001

(3) The Kinetix® 6000 drive is shown as an example of any drive or other device in configuration with the line interface module;

however, noise zones of other products will vary.

I/O Signals

The 2094-ALxxS, 2094-BLxxS, and 2094-XL75S-Cx line interface module I/O
(IOL) signals include the contactor coil, alarm contacts, status contacts, and I/O
power supply.

This table provides a description and electrical specifications for the IOL
connector signals. See Power Specifications
specifications.

Line contactor coil connections with an auxiliary contac t from the control power circuit
breaker wired in series with the contactor coil. The line contactor is a safety contactor that
includes three main contacts with four auxiliary contacts (see figure on page 19).

Four pairs of auxiliary contacts that are normally-closed on the line contactor (see figure
on page 21).

Power supply capable of supplying 24V @ 6 A for I/O functions and switches. Each set of
pins is capable of 2 A. To use the full rating of the supply, all pins must be used to provide
the appropriate current rating (see figure on page 23

).

See Power Specifications beginning on page 52 for auxiliary contactor
specifications.

CB1 Alarm Operation

The CB1 alarm circuitry (ALRM_M contact) in the 2094-ALxxS, 2094-BLxxS,
and 2094-XL75S-Cx line interface modules is closed only when CB1 trips
(meaning input current exceeds instantaneous current trip setting) and not
dependant on the ON/OFF switch. The ALRM_B contact is closed when CB1
is manually set to the ON or OFF position, and open when CB1 is tripped.
