detach the EMI/RFI Block Cover by removing four screws. Then, after
making the connections, ensure that the Block Cover is securely remounted
over the terminal block to insure EMI/RFI protection of the 402R-EU.
NOTE: Some features displayed on the terminal strip may not be present in your
system, i.e., no alarms.

The standard version of the 402R-EU is designed and specified to
function properly for mains (line) voltage in the range 115VAC ±10% at
50Hz or 60Hz. For the 230V version this range of voltages is 230VAC
±10% at 50Hz or 60Hz.
Subjecting the 402R-EU to mains (line) voltages which are either
higher than or lower than these ranges can cause permanent demage to
the 402R-EU.
If the unconditioned mains (line) voltages are expected to exceed
these ranges, the use of some form of voltage conditioner (such as an
uninterruptible power supply) should be used to protect the 402R-EU.
A source of single phase, 115V± 10% (or 230V±10%), 50 or 60 Hz
power will be required to operate the analyzer electronics. The nominal
valt-amp consumption of the analyzer is 150VA..
The primary power is connected to an IEC connector in the power
entry module at the rear of the 402R-EU. This power entry module also
contains the EMI/RFI line filters and holds the two 5mm x 20mm main
(line) fuses. These fuses may be replaced by using a small bladed screw-
driver to pry out the cover plate ( marked “USE ONLY 250V FUSES”).
This cover plate is the outside surface of the fuse carrier. The line fuses
used are manifactured by LITTELFUSE INC., their part number: 21501.6.
Only this manafacturer, and manufacturer’s part number fuse may be
used for replacement. This is a 250V, 1.6A fuse with a current
interupting rating of 1500A and a nominal melting I
2 t rating of 3.9 A 2 Sec.
The main (line) cord used to power the 402R-EU must contain a
safety ground wire and this must be connected to a safety earth ground
such as a proper cold water pipe ground. In addition to this safety ground
connection the 402R-EU, a safety ground wire (green - yellow, AWG #16)
must be connected to the proctective earth ground 8-32 screw marked with:
This ground wire must be connected to this screw by a ring-lug with
external star lock washers on both sides of the lug. After the lug and
