Warning
!
Attempts to install or remove S7-200 modules or related equipment when they are
powered up could cause electric shock.
Failure to disable all power to the S7-200 modules and related equipment during
installation or removal procedures may result in death or serious personal injury, and/or
damage to equipment.
Always follow appropriate safety precautions and ensure that power to the S7-200
modules is disabled before installation.
Use the following procedure for installing an S7-200:
1. Locate, drill, and tap the mounting holes for DIN M4 or American Standard number 8
screws. Refer to Section 2.1 for mounting dimensions and other considerations.
2. Secure the S7-200 modules onto the panel, using DIN M4 or American
Standard number 8 screws.
If you are installing an expansion module, use the following steps:
1. Remove the bus expansion port cover from the existing module housing by inserting a
screwdriver into the space between the bus expansion port cover and the housing, and
gently prying. Ensure that the plastic connecting joints are completely removed. Use
caution not to damage the module. Figure 2-9 shows proper screwdriver placement.
2. Insert the bus connector into the bus expansion port of the existing module and ensure
that the connector snaps into place.
3. Ensure that the expansion module is correctly oriented with respect to the CPU module.
If you are using an expansion cable, orient the cable up towards the front of the module.
4. Connect the expansion module to the bus connector by sliding the module onto the bus
connector so that it snaps into place.
