Installation

2.1 INSTALLATION CONSIDERATIONS

The Training Panel is shipped fully assembled and wired. An overview of the installation follows.
1.
Place the Training Panel on a desktop or other level surface convenient to a source of electrical power. Refer to
Sections 1.2 Specifications and 2.3 Environment.
To move or carry a Training Panel, either firmly grasp the metal front panel or cup your
hand beneath the underside of the controller case and grasp the case where case and front
panel meet. A Training Panel should not be lifted or carried by the wiring cover on the
top of the controller case. The cover can bend causing the Panel to be dropped.
2.
Ensure that the Training Panel is wired for the supply voltage required by the controller's MPU Controller
board. Unless otherwise specified on the order, a standard three prong, grounded plug for AC power is supplied.
The power cable and plug are not shown in the figures. The Training Panel can be field wired for DC power.
Refer to Section 2.4 in this manual.
3.
Install a controller in the Training Panel case. At minimum, a Model 353 Display Assembly and MPU
Controller board must be installed. Install additional boards as required by the process simulation, training
curriculum, or controller configuration to be developed or run. The Display Assembly, MPU Controller board,
I/O Expander board, and communication option boards are supplied by the user, unless included in the Training
Panel purchase.
4.
Make the necessary external connections to the various terminals of the Panel's front panel.
5.
Connect the Panel's power cable to an electrical power source.
Multi-Purpose Training Panel dimensions are shown in Figure 2-1.

2.2 CIRCUIT BOARD HANDLING GUIDELINES

An electrostatic discharge can damage the semiconductor devices on a circuit board assembly!
Semiconductor devices must be protected from electrostatic discharge. A properly grounded conductive
wrist strap must be worn whenever a circuit board assembly is handled or touched. A PN 15545-110 service kit
with a wrist strap and static dissipative workmat is available from Siemens Energy & Automation, Process
Industries Division. Equivalent kits are available from mail order and local electronic supply companies.

2.3 ENVIRONMENT

Select a level surface that is convenient to a source of electrical power. The surface area should be sufficient for the
Training Panel plus configuration and training materials. The Panel is intended for use in an indoor location under
normal room conditions; see Section 1.2 Specifications for additional information. For other controller
environmental specifications, refer to the Model Designation and Specifications section in UM353-1. The Training
Panel should not be operated in a location where direct sunlight can shine on the case or display. Direct sunlight can
make the LEDs on the Display Assembly and Training Panel difficult to read and can interfere with controller heat
dissipation.
