4Line Interface Module
Mounting Requirements
The following requirements apply when preparing to mount your line interface
module:
•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 and CE requirements. A NEMA 4X enclosure exceeds
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 on page 55.
•Maintain minimum clearances for proper airflow, easy module access, and
proper cable bend radius as shown in the figures on page 5.
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.
IMPORTANT
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 dirty 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.

CB1 Alarm Operation
The CB1 alarm circuitry (ALRM_M contact) in the 2094-ALxxS, 2094-BLxxS,
and 2094-XL75S-Cxline 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.

Contactor Coil
For safety reasons, the internal wiring is arranged so that if the control power
(CPL) circuit breaker (CB2) trips, the opening contact will interrupt the coil
voltage and remove main input power to the drive.
The 2094-ALxxS, 2094-BLxxS, and 2094-XL75S-Cxline interface modules use
an AC coil and a DC interface module allows the contactor coil to be controlled
by the 24V DC output of the drive. Additional surge suppression is not required
for these contactors.
Figure 13 - IOL Contactor Coil
(catalog numbers 2094-ALxxS, 2094-BLxxS, and 2094-XL75S-Cx)
The contactors in the 2094-AL09 and 2094-BL02 line interface modules use a
DC coil. The contactor coil voltage is 24V DC with a suitably-rated surge
suppressor fitted inside the line interface module.

Safety Contactor
The safety contactor includes three main contacts (normally-open) that close
when coil power is applied.
The three auxiliary (safety) contacts (used in 2094-ALxxS, 2094-BLxxS, and
2094-XL75S-Cxline interface modules) are volt-free, positively-guided, and
mechanically-latched.

See Power Specifications on page 52 for auxiliary contactor specifications.
IMPORTANT
A fourth volt-free normally-open contact is also available, but is not safety rated and
should not be used in a safety string.
