Siemens S-40EXIT - Recommended Battery and Wire Requirements; Foundations

4
FOUNDATIONS
Prefabricated galvanized steel or poured concrete may be used for the foundation.
When using Safetran’s galvanized steel foundation, part number 035903-500X, be sure bottom of
excavation is flat and level to insure full support to the base plate. Backfill should be compacted, with
height of exposure above ground limited to 4 inches.
Place foundation as dictated by local conditions and clearance requirements, remembering that gate
arm lengths are measured from center of foundation to end of arm.
For field poured concrete foundation, 4 anchor bolts, part number 131702-26X, are required.
RECOMMENDED BATTERY AND WIRE REQUIREMENTS
Sizes of wire used for the motor circuit should be calculated so that there will be not more than
0.1 ohm resistance between the battery and mechanism terminals.
Wire sizes as follows are recommended:
The following battery is recommended with above wire sizes for gates of various lengths:
