Connecting Power And Ground - Motorola ACE3600 RTU Owner's Manual

Connecting Power and Ground

All internal electrical connections except for the main power, ground and battery are performed
in the factory and supplied with the RTU. The electrical interconnection diagrams are
provided in the Break-Fix Procedures chapter.
The procedures for the main power, ground and battery connections are provided below.
The power and ground connections should be performed only by qualified
and authorized service personnel. All power and ground connections
must be in accordance with local standards and laws.
Per UL 60950 / EN 60950, for all I/O modules connections, the maximum
voltage should not exceed 60V DC or 30 V AC unless it is specifically
written otherwise.
To maintain Overvoltage (Installation) Category II, install a suitable surge
suppressor device in the branch circuit to limit expected transients to
Overvoltage Category II values. The limits are based on IEC60664 and are
also located in Table 2H of UL60950 (for mains = 150V, the transient rating
is 1500V; for 150V < mains = 300V, the transient rating is 2500V; and for
300V < mains = 600V, the transient rating is 4000V).
