Hardware installation safety warnings
1) WARNING
: Because of the dangerous currents,
voltages, and forces encountered, safety
precautions must be taken for all tests. Follow all
corporate guidelines and those included here. Due
to the wide diversity of machine applications, no
attempt is made here to list or review all specific
manifold general safety precautions. However,
this manual includes special safety precautions
applicable to the use of the EXP4000.
2) NOTICE
: The maximum rating of the EXP4000 is
1,000 V (500 V for DC operation). 1,000 V (500 V
DC operation) is the maximum allowable voltage
between any two of the four voltages and the
ground clip. Under no circumstances connect the
voltage sensing circuit to higher voltage levels,
this will cause severe damage to instrument.
3) NOTICE:
The maximum voltage rating of the
EP1000 current transformers is 600 V. Under no
circumstances connect the current sensors to
circuits of any higher voltage, this may cause
severe damage to instrument.
Other installation safety warnings
Baker Instrument Company, an SKF Group Company
recommends the following safety precautions:
1) Comply with all your facility’s safety practices at all
times.
2) Ensure physical setup does not interfere with your
facility’s current or intended operation.
Additionally, these safety precautions must be followed,
otherwise dangerous shock hazards may exist:
1) Use whatever safety equipment required by your
organization including eye protection, high voltage
gloves, arc-flash rated masks, hoods and any
required PPC. Prior to opening any MCC (Motor
Control Cabinet), ensure that appropriate arc-
flash protection clothing is worn.
2) Ensure that appropriate lockout / tag-out
procedures are properly understood and
implemented by all personnel.
DANGER: To prevent serious injury
or death cabinet voltage must be de-
ener
g
ized for installation.
3) Ensure motor’s phase connections are not
positioned near ground or near each other.
NOTE: It is necessary that each EP1000 is provided
three- phase voltage (not in excess of 1,000 V AC), and
a good ground. Some switchgear installations will
require this voltage to be wired from the bus cabinet to
each cabinet being outfitted with an EP1000. For
motors rated at voltages higher than 1,000 V AC,
secondary output voltage from the PTs are acceptable
as long as all three phases are present as line to line
voltages, and are lower than 1,000 V AC.
