105.4 Electronics Cabinet Voltage Check
Using a digital volt-ohm meter, check for correct nominal battery voltage between electronics cabinet DC Input NEG
and POS wires. Refer to table in section 105.3 for proper system DC voltage. Voltage reading should be ±10% of
system DC voltage.

CAUTION
A. All Synchron inverter system units contain hazardous AC and DC voltages. Because of these voltages, a
qualied electrician must install the Synchron inverter system, AC line service, and batteries. The electrician
must install the AC line service according to local, state and NEC codes and must be familiar with batteries and
battery installation.
B. Before installing, maintaining, or servicing the unit, always remove or shut off all sources of AC and DC power
and shut off the Synchron inverter system. Disconnect AC line input at the service panel and turn off the Main DC
Switch and the Main AC Switch to make sure the unit will not supply output voltage.
C. Whenever AC and/or DC voltage is applied, there will be AC voltage inside the Synchron inverter system unit; the
unit can supply power from AC line or from its batteries. To avoid equipment damage or personal injury, always
assume that there may be voltage inside the Synchron inverter system.
D. Remove rings, watches, and other jewelry before installing the AC wiring. Always wear protective clothing and eye
protection and use insulated tools when working near batteries. Whenever servicing an energized unit with the
inside panel open, electric shock is possible; follow all local safety codes. TEST BEFORE TOUCHING!
E. To reduce the risk of re or electric shock, install the Synchron inverter system and the batteries in a temperature-
controlled and humidity-controlled indoor area free of conductive contaminants. See Section 103 for operating
environment specications.
106.1 AC Wiring Preparations
1. Open or remove the system's front cover/door. Make sure all breakers are in the off position.
2. Make sure the Synchron inverter system input and output voltages are correct for the particular application.
Remember that the Synchron system provides single-phase power only.
3. The input circuit breaker in the input service panel provides the means for disconnecting AC to the Synchron
inverter system. Only authorized persons shall be able to disconnect AC to the unit. (See NEC 700-20 and 700-
21.)
