390G+ INSTALLATION INSTRUCTIONS
2
Prep the gate and post according to the instructions or in accordance with the requirements of the
situation. Note that some installations may require additional brackets, hardware, or reinforcement
for a sound installation. Loosen the socket cap screws which secure the standard mounting brack-
et to the magnetic lock assembly and remove the bracket. (The socket head cap screws are cap-
tured in the magnetic lock assembly.) Slide the TJ mounting plate onto the magnetic lock assem-
bly. Center it and secure with two 6-32 set screws. Install the armature housing to the lower TJ
bracket using the two #6-32 flat head machine screws. Do not remove the foam rubber compres-
sion pads. Pre assemble the armature assembly to the lower TJ bracket as shown (left). Note that
the tapered washer assembles with the pointed side toward the armature, then the external tooth
washer, followed by the flat washer. Next, slide the dress plate into the lower TJ bracket and
secure in position with one of the #6-32 set screws.
Mount the standard mounting plate onto the gate post using either the two #10 pan head self tapping
screws and washers or the 10-24 pan head machine screws. Do not completely tighten them at this
time because the position of the bracket must be adjustable in the next step. Fasten the magnetic lock
assembly to the mounting plate using the 2/16 hex wrench provided.
Mount armature/lower TJ bracket assembly to moving part of gate using two 1/4-20 button head sock-
et cap screws and washers. (Alternate hardware may be substituted if necessary.) Close the gate and
secure it (if such mechanical means exists). With the gate in its closed position, push the magnetic
lock toward the armature so that it comes to rest completely engaged, with no air gap. (If a temporary
power supply is available to power up the lock do so in order to ensure that the lock will properly
engage.) Mark the position of the magnetic lock assembly. Remove the magnetic lock and tighten the
two pan head screws.
Open gate. Using the standard mounting bracket as a template, drill the four remaining holes for #10
self tapping or #10-24 machine screws as appropriate. Install screws, tightening completely. Install
magnetic lock, tightening socket screws completely.
Run conduit to lock and make wiring connections for the voltage being used. See page 1 for wiring
and monitor switch information. If the lock is used in a particularly corrosive environment such as near
salt water or in a climate where salt is applied on the roads apply a thin film of grease (supplied) to the
mating surfaces of the magnet and the armature.
