1.0 Installing the Meter

INSTALLATION

The meter meets NEMA Type 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.

2.0 Setting the DIP Switches

To access the switches, remove the rear cover of the meter as described

below. A bank of 4 switches is located in the upper right hand corner. After

setting the switches, install any optional plug-in cards before replacing the rear

cover (see next section).

Warning: Exposed line voltage exists on the circuit boards. Remove

all power to the meter and load circuits before accessing inside of

the meter.

REMOVE/REPLACE 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.

SETTING THE INPUT DIP SWITCHES

The meter has four DIP switches for Input A and Input B that must be set

before applying power.

SWITCH 1

LOGIC: Input A trigger levels VIL = 1.25 V max.;

VIH = 2.75 V min.; VMAX = 28 VDC

MAG: 200 mV peak input sensitivity; 100 mV

hysteresis; maximum input voltage: ±40 V peak

(28 Vrms); Must also have SRC switch ON.

(Not recommended with counting applications.)

SWITCH 2

SNK.: Adds internal 7.8 KΩ pull-up resistor to +9 to

28 VDC, IMAX = 3.8 mA.

SRC.: Adds internal 3.9 KΩ pull-down resistor,

7.2 mA max. @ 28 VDC max.

Factory Setting

SWITCHES 3 and 4

HI Frequency: Removes damping capacitor and allows max. frequency.

LO Frequency: Adds a damping capacitor for switch contact bounce. Limits

input frequency to 50 Hz and input pulse widths to 10 msec.
