PRODUCT DESCRIPTION
TM
The
SMART EMS
is a completely self-contained120 volt power distribution and energy management system
intended to be used in recreational vehicles. It is housed in a sheet metal enclosure with removable front panel. It
provides circuit protection for all the 120 VAC loads in the RV and a system of energy management to minimize the
over-loading and tripping of circuit breakers.
TM
Circuit Breakers
- the
SMART EMS
offers slots for four single or dual, standard 120 volt circuit breakers. One of
these breakers must be a 30 Amp unit that acts as a main input protection for the remainder of the branch breakers
(up to 7).
TM
Energy Management
- the
SMART EMS
offers control of up to four, 120 volt operated appliances to help keep the
total 120 volt current draw to less than 30 Amps. These appliances may be any type load, but are typically heavier
loads, those whose use can be "postponed" until a time when current is available for their use.

SERVICE MANUAL CAUTION The SMART EMS is a centralized power switching, fusing, and distribution center. Power from the 120 volt power source is fed into the box. The potential of lethal electrical shock is present in this box. Inadvertent only shorts at this box could result in damage and/or injury. -
Page 3: Operation
SMART EMS SERVICE MANUAL OPERATION In operation, when the 120 VAC and 12 VDC are applied, the system will energize the relays, one at a time. The three AC relays and two DC relays will move from the N/O to N/C position. -

Page 9: Performance Test
SMART EMS SERVICE MANUAL PERFORMANCE TEST The system is now ready for testing. Hi-POT TEST At the installers preference, to assure there are no potential shorts, a Hi-Pot test can be performed on the installation. To do this, +12 volts must be applied to the system. A jumper wire must be installed to tie the two pins of the "Hi-Pot Test" plug, J1, to turn the system on without the presence of 120 volt power. - Page 10 SMART EMS SERVICE MANUAL The replacement circuit breakers must be of the same type and rating. FUSE - 3 Amp ATO type, for EMS circuitry only. DO NOT replace with a fuse of higher rating. This could result in severe damage to the circuitry or create a possible fire hazard.
