Chapter 4 Install the Module
ATTENTION: Wire the POINT Guard I/O modules properly so that 24V DC line
does not touch the safety outputs accidentally or unintentionally.
Do not connect loads beyond the rated value to safety outputs.
Wire conductors correctly and verify operation of the module before placing the
system into operation. Incorrect wiring can lead to loss of safety function.
Do not apply DC voltages that exceed the rated voltages to the module.
Do not connect a power source to the sensor power supply in the 1734-IE4S
module or you could blow an internal fuse. When an internal fuse is blown, the
module is inoperative.
Disconnect the module from the power supply before wiring. If wiring is performed
while power is supplied, devices that are connected to the module can operate
unexpectedly.
WARNING: If you connect or disconnect wiring while the field-side power is
on, an electric arc can occur. This arc could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
This equipment must be used within its specified ratings that Rockwell
Automation has defined.
ATTENTION: This product is grounded through the DIN rail to chassis ground.
Use zinc plated chromate-passivated steel DIN rail to assure proper grounding.
The use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately. Be sure to ground the DIN rail
properly. Refer to Industrial Automation Wiring and Grounding Guidelines,
Rockwell Automation publication 1770-4.1
, for more information.
