ESD Protection
Potential Damages Caused by Exposure to ESD
To prevent electrostatic discharge (ESD) damage to LectroCount register electronic components, all
LectroCount electronic register truck intallations are required to properly ground truck seat(s) cushions
and Epson printers.
Prolonged exposure to ESD over weeks, months, or years can corrupt LectroCount registers’ CPU
memory and damage the electronic components in LectroCount registers (as well as other electrical
components in the truck’s electrical system).
Adjustable, shock-absorbing seats, if not grounded correctly, generate significant amounts of ESD. The
pivots and hinges of these seats isolate the seat cushion from an electrical ground. Without an electrical
ground, ESD builds between the seat cushion and the operator. This built-up ESD can be transferred
back to the LectroCount register from any point of the truck’s electrical system, such as the cabling from
the LectroCount register to the cab or the Epson printer.
Liquid Controls Grounding Kits
To protect electronic components from ESD, all LectroCount truck intallations must include the installation
of the LectroCount Ground Strap Kit (PN 82185) and the Epson Printer Ground Wire Kit (PN 82184).
Properly grounded seats allow static electricity to “bleed off” the driver and the seat before it can build
up, discharge, and damage the LectroCount register or any of the truck’s other electrical components.
The LectroCount Ground Strap Kit will be included with all future LCR 600 LectroCount register
shipments, and the Epson Printer Ground Wire Kit will be included with all future Epson printer cable kit
shipments. Effected part numbers are listed below. For existing installations and previously purchased
LectroCount registers and Epson printers, both ground kits are available from LC.
ESD Procedural Precautions and LectroCount Register
Grounding Installation Notes
When installing or performing maintenance on a LectroCount register, there are certain guidelines that
must be followed to safeguard against ESD damage.
REGISTERS NOT MOUNTED DIRECTLY TO THE METER
In typical LectroCount installations where the LectroCount register is mounted directly to the meter, the
LectroCount housing is grounded through the meter. If the register is not mounted on the meter, you must
make sure the LectroCount housing is grounded properly.
