CAUTION
Remove the battery pack before wiring. Refer to
subsection 8.3 “Replacing the Battery Pack” for
the battery pack removing.
Wiring to Ground Terminal
Protect the cable of the ground terminal by using
heat-shrink tubing, etc. Use a ring tongue terminal
for M4 terminals with an insulation sleeve.
5.5 Grounding
Class D grounding with the grounding resistance
of 100Ω or less is necessary. To connect the
grounding cable to FN310 directly, use the ground
terminal on the top of the housing. Do not share the
ground wiring with other devices.
Ground Wiring
Connect the grounding cable to ground terminal on
the top of the housing.

CAUTION
Grounding is required for safe operation.
Input Cable Wiring
The input cable shield should be connected to
grounding terminal inside of the housing.
• The input cable shield should not be connected
to grounding terminal inside of the Modbus
device.
• Connection to the ground terminal of Modbus
device housing, refer to the User's Manual.
IMPORTANT
Proper grounding is necessary to maintain the
function and performance of this product. When
the grounding is inadequate, the equipment may
be damaged.
Refer to TI 01W01A58-01EN for details of
grounding method and precautions.
• Use a grounding cable of AWG 14 (2 mm
2
) or
more between the grounding electrode and
the grounding terminal of this product, and
connect with the shortest route.
• Select the grounding cable that has a
structure of adequately protects against
mechanical damage, chemical or electrical
degradation, electrodynamic force and
thermodynamic force for connection of the
grounding electrode and the ground terminal
of this product.
