Installation
The meter meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert the unit into the panel cutout.
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel latch
should be engaged in the farthest forward slot possible. To achieve a proper seal,
tighten the latch screws evenly until the unit is snug in the panel (Torque to
approx. 28 to 36 in-oz [0.202 to 0.26 N-m]). Do not over-tighten the screws.
Installation Environment
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
The bezel should only be cleaned with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate the
aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.

SETTING THE INPUT DIP SWITCHES
The meter has four DIP switches for Input A and
Input B that must be set before applying power.
SWITCHES 3 and 4
HI Frequency
: Removes damping capacitor and
allows max. frequency.
LO Frequency
: Adds a damping capacitor for switch
contact bounce. Also limits input frequency to 50
Hz and input pulse widths to 10 msec.
SWITCH 2
SRC.
: Adds internal 3.9 K
Ω
pull-down resistor,
7.7 mA max. @ 30 VDC max.
SNK.
: Adds internal 7.8 K
Ω
pull-up resistor to +9 to
28 VDC, I
MAX
= 3.8 mA.
SWITCH 1
LOGIC
: Input A trigger levels V
IL
= 1.25 V max.; V
IH
= 2.75 V min.
MAG
: 200 mV peak input (must also have SRC on). Not recommended with
counting applications.
To access the switches, remove the rear cover of the meter. A bank of 4
switches is located in the upper right hand corner.
Warning
: Exposed line voltage exists on the circuit boards.
Remove all power to the meter and load circuits before accessing
inside of the meter.
REMOVING THE REAR COVER
To remove the rear cover, locate the cover locking tab below the 2nd and 3rd
input terminals. To release the tab, insert a small, flat blade screwdriver
between the tab and the plastic wall below the terminals. Inserting the
screwdriver will provide enough pressure to release the tab locks. To replace the
cover, align the cover with the input terminals and press down until the cover
snaps into place.
