WARNING: Servicing energized industrial equipment can be
hazardous. Severe injury or death can result from electrical
shock, burn, or unintended actuation of controlled equipment.
Recommended practice is to disconnect and lock out control
equipment from power sources, and allow stored energy in
capacitors to dissipate, if present. If it is necessary to work in
the vicinity of energized equipment, the safety related work
practices of NFPA 70E, Electrical Safety Requirements for
Employee Workplaces, must be followed.
WARNING: Use of other than factory recommended test
equipment as detailed below for solid state controls may result
in injury to personnel, damage to the control or test equipment
or unintended actuation of the controlled equipment.
Potentially fatal voltages may result from improper useage of
an oscilliscope or other test equipment. Refer to equipment
safety instructions for all test equipment before using with the
MCA board. All cautions and warnings that apply to servicing
and troubleshooting a 1395 Drive found in the 1395 Instruction
Manual, MUST be followed when servicing the MCA board.
Recommended Tools and Equipment – The following equipment is
recommended for maintaining and troubleshooting a 1395 Drive and MCA
board:
S Multimeter capable of 1000V DC/ 750V AC, with input resistance of at
least 1 megohm minimum.
S Test leads for multimeter
S Assorted screwdriver (phillips and blade) and a set of open end
wrenches.
S Clamp on Ammeter (AC and DC with current ratings to match drive
ratings).
S Programming Terminal
S Dual trace oscilliscope with A minus B quasi differential capability.
S X100 probes for oscilliscope.
