MOUNTING INSTRUCTIONS
This operator interface is designed for through-panel mounting. A panel cut-
out diagram and a template are provided. Care should be taken to remove any
loose material from the mounting cut-out to prevent that material from falling
into the operator interface during installation. A gasket is provided to enable
sealing to NEMA 4X/IP66 specification. Install the 14 kep nuts provided and
tighten evenly for uniform gasket compression.
Note: Tightening the kep nuts beyond a maximum of 17 inch-pounds (1.92
N-m) may cause damage to the front panel.
CONNECTING TO EARTH GROUND
Each TS8010 has a chassis ground terminal on the back of the unit. Your unit
should be connected to earth ground (protective earth).
The chassis ground is not connected to signal common of the unit.
Maintaining isolation between earth ground and signal common is not required
to operate your unit. But, other equipment connected to this unit may require
isolation between signal common and earth ground.
To maintain isolation
between signal common and earth ground care must be taken when connections
are made to the unit.
For example, a power supply with isolation between its
signal common and earth ground must be used. Also, plugging in a USB cable
may connect signal common and earth ground.

in turn may also be connected to signal common.
POWER SUPPLY REQUIREMENTS
The units require a 24 VDC power supply rated at 30 W. Your unit may draw
considerably less than the rated power depending upon the options being used.
As additional features are used your unit will draw increasing amounts of power.
Items that could cause increases in current are additional communications,
optional communications card, CompactFlash card, and other features
programmed through DSI8000.
In any case, it is very important that the power supply is mounted correctly if
the unit is to operate reliably. Please take care to observe the following points:
– The power supply must be mounted close to the unit, with usually not
more than 6 feet (1.8 m) of cable between the supply and the operator
interface. Ideally, the shortest length possible should be used.
– The wire used to connect the operator interface’s power supply should
be at least 22-gage wire. If a longer cable run is used, a heavier gage
wire should be used. The routing of the cable should be kept away from
large contactors, inverters, and other devices which may generate
significant electrical noise.
– A power supply with an NEC Class 2 or Limited Power Source (LPS)
and SELV rating is to be used. This type of power supply provides
isolation to accessible circuits from hazardous voltage levels generated
by a mains power supply due to single faults. SELV is an acronym for
“safety extra-low voltage.” Safety extra-low voltage circuits shall
exhibit voltages safe to touch both under normal operating conditions
and after a single fault, such as a breakdown of a layer of basic
insulation or after the failure of a single component has occurred.

The protective conductor terminal is bonded to conductive
parts of the equipment for safety purposes and must be
connected to an external protective earthing system.

Each option card comes with a cable for communications and three
screws for attaching the option card to the TS’s main board.
To install the option card, remove all power and I/O communications
cables from the unit and remove the rear cover. Connect the cable from the
option card to the connector on the main board. Be sure both ends of the
cable are firmly seated into their appropriate connector housings. Use the
three screws provided to mount the option card to the main board as shown
in Figure 1.
Carefully replace the rear cover by reversing the instructions for
removing the rear cover.
