3.0 INSTALLATION
This section describes how to install and remove the module and its
cable assemblies.
DANGER
ONLYQUALIFIED ELECTRICAL PERSONNEL FAMILIAR WITH THE
CONSTRUCTION AND OPERATION OF THIS EQUIPMENT AND THE HAZARDS
INVOLVED SHOULD INSTALL, ADJUST, OPERATE, AND/OR SERVICE THIS
EQUIPMENT. READ AND UNDERSTAND THIS MANUAL IN ITS ENTIRETYBEFORE
PROCEEDING. FAILURE TO OBSERVE THIS PRECAUTION COULD RESULT IN
SEVERE BODILYINJURYOR LOSS OF LIFE.
DANGER
THE USER IS RESPONSIBLE FOR CONFORMING WITH ALL APPLICABLE
LOCAL, NATIONAL, AND INTERNATIONAL CODES. WIRING PRACTICES,
GROUNDING, DISCONNECTS, AND OVERCURRENT PROTECTION ARE OF
PARTICULAR IMPORTANCE. FAILURE TO OBSERVE THIS PRECAUTION COULD
RESULT IN SEVERE BODILYINJURYOR LOSS OF LIFE.
3.1 Wiring
To reduce the possibility of electrical noise interfering with the proper
operation of the control system, exercise care when installing the
wiring from the system to the external devices. For more detailed
recommendations, refer to IEEE 518.
3.2 Initial Installation
Use the following procedure to install the module:
Step 1.
Turn off power to the system. All power to the rack as well
as all power to the wiring leading to the module should be
off.
DANGER
THIS EQUIPMENT IS AT LINE VOLTAGE WHEN AĆC POWER IS CONNECTED.
DISCONNECT AND LOCK OUT ALL UNGROUNDED CONDUCTORS OF THE AĆC
POWER LINE. FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT IN
SEVERE BODILYINJURYOR LOSS OF LIFE.
Step 2. Mount the terminal boardassemblies on a flat panel
(M/N 61C547) or a DIN rail (M/N 61C548). See figure 3.1.
The terminal boards shouldbe mountedto allow easy
access to the screw terminals. Be sure the terminal board
assemblies are close enough to the rack so that the cables
(M/N 61C547 or M/N 61C548) will reach between them
andthe Voltage Input module in the rack. The cables are
five feet long. See figure 3.2.
