Rev. C December 1998
Field Wiring
Before installation, the system specifier must determine the proper wire gauge for all field wiring. The field wiring is broken down
into two categories, inputs and outputs.
NOTE: All field wiring shall conform to applicable codes and standards including NFPA, UL, local, state, county, province, district
and federal codes and standards.
Field Wiring Connection
All wiring terminals are designed to accept #22 AWG to #12 AWG wiring (one wire per terminal). Connect the field wiring to the
terminals while referring to the following sections.
Install field wiring following the latest National Electrical Code and local codes for the type of system being installed. Make all
necessary connections. See Figure 4 for typical system block diagram.
Check the integrity of all field wiring following directions in the "Field Wiring Checkout" section. Confirm that the specified cable is
installed and there is continuity between required points (no "open circuits"), with no unwanted connections ("shorts") to other
conductors, chassis, or earth ground.
Perform the field wiring checkout before continuing with any connections to the wiring
terminals.
WARNING: TO REDUCE THE RISK OF ELECTRICAL SHOCK, NEVER CONNECT OR DISCONNECT FIELD WIRING
WHEN INPUT VOLTAGE OR BACK-UP BATTERIES ARE CONNECTED TO THIS SAFEPATH PANEL.
Input Wiring Descriptions
This panel has four types of inputs, the locations of which are shown in Figure 5. Detail of the power input and ground terminals is
shown in Figure 6.
Line Level Input Wiring
Determination of the wire gauge for the line level input wiring should consider all factors, including wire loop length and the
maximum allowable wire loop resistance of 10 ohms. The line level input wiring diagram’s are shown in Figure 7.
AC Input Voltage Wiring
Determination of wire gauge for the input voltage wiring should consider all factors, including wire loop length, AC power line
voltage, the panel’s maximum AC current consumption, and the panel’s AC input voltage range.
IT IS IMPORTANT THAT THE WIRING USED FOR INPUT VOLTAGE WIRING IS LARGE ENOUGH TO CARRY THE MAXIMUM
CURRENT REQUIRED BY THIS SAFEPATH PANEL WITHOUT EXCESSIVE VOLTAGE DROP. IF VOLTAGE DROPS FROM AC
POWER LINE LOADING AND WIRING RESISTANCE ARE NOT WITHIN THE SPECIFIED OPERATING VOLTAGE RANGE, THE
SAFEPATH PANEL WILL NOT FUNCTION PROPERLY.
A typical AC input voltage wiring diagram is shown if Figure 8. This panel shall have its own branch circuit on the main power panel.
The wiring from the main power panel shall terminate in the SAFEPATH panel on the power supply terminals as shown in Figure 8.
Wire jumpers shall then be run from the battery charger terminals to the power supply terminals as shown in Figure 8. The wire
jumpers between the battery charger terminals and the power supply terminals shall be the same gauge as the wire between the
main power panel and this panel.
Battery Wiring
Determination of the wire gauge for the battery wiring should consider all factors, including wire loop length and the maximum
allowable wire loop resistance. The maximum wire loop resistance is 0.05 ohms. A typical battery wiring diagram is shown in Figure
9.
Earth Ground Wiring
Determination of the wire gauge for the earth ground wiring should consider all factors, including wire length and the maximum
allowable wire resistance. A typical earth ground wiring diagram is shown in Figure 10.
If the RSAPE is connected to the direct output of the amplifier at the audio outputs on the SAMB-A, then wire to the LLIM as shown
in Figure 7A. If the RSAPE is connected to the output of a splitter (SPL, SC-SPL), then wire to the LLIM as shown in Figure 7B.
