SECURITY SEAL INSTALLATION
The indicator on the EU522 / EU522HR and EU544 has been designed for attachment of three
separate lead-wire security seals. Two seals prohibit access to the calibration switch while a
third seal prevents the scale cable from being disconnected from the indicator (see Figure A).
Local metrology laws may or may not require these security seals. If your metrology laws
require these security seals, follow the directions provided below to install each of the seals.
Calibration Seal
1. Make certain the fillister screws (in the end cap and on the rear panel) are securely
tighten before proceeding.
2. Thread the sealing wire through the hole in both
fillister head screws as shown.
3. Pull the wire tight and install the lead seal. Refer to Figures B and C.
4. The screws can not be removed without damaging the seal.
Load Cell Cable Connection
1. Make certain the load cell cable is securely tightened to the 9-pin “D” connector on the
rear of the indicator before proceeding.
2. Thread the sealing wire through the hole in the connector and the fillister head screw
securing the ground lug on the rear of the indicator as shown in Figure D.
3. Pull the wire tight and install the lead seal.
