The EL232 XPCD explosion proof remote display represents the latest in state-of-the-art microprocessor
technology specifically applied to the explosion proof weighing marketplace. This EL232 has been modified for
use in a hazardous electrical environment.
This manual provides information on installation of the EL232 XPCD. The installer should be familiar with the
National Electrical Code and RP 12.6 (
Recommended Practice ) requirements for installation of equipment in
hazardous areas (NEC Article 504, Intrinsically Safe Systems ) published through the Instrument Society of
