STEP 1
Position the post mounting bracket (A from component list on page 3) and gate mounting
bracket (B from component list on page 3) using the dimensions in the table depending upon
the operator used (Phobos BT N or Phobos BT NL) and depending upon the desired opening
angle (90 degrees or 110 degrees). Secure post bracket (A from component list on page 3) by
welding or bolting.
STEP 2
Position the gate mounting bracket (B from component list on page 3) so that the distance
betweenthepostandgatebracketrotationpointsis273/4“forPhobosBTNand32½”
for Phobos BT NL (pull to open) with the gate fully closed. Secure gate bracket (B from
component list on page 3) by welding or bolting.
Note: Do not mount gate bracket (B from component list on page 3) on vertical pickets.
Instead, weld a plate or a bar horizontally across several pickets for reinforcement. Install
both the gate and post brackets in a position to ensure that the actuator is level.
STEP 3
Install the Phobos BT N or BT NL on the mounting brackets and secure with retainer C clips
provided in the kit.
STEP 4
Mount the Libra UL R or large enclosure box in close proximity to the Phobos BT N or BT NL
in accordance with local electrical regulation.
