Installation
1.1
Mounting
Th
e RHF is designed with simple installation in mind. The system is
wall mounted using four #10 bolts. To mount the RHF on the wall,
install two #10 bolts on the wall rated to support the charger
weight plus a safety factor of at least two times. Place the RHF on
the bolts, add appropriate mounting hardware and tighten. Add the
additional two bolts with the appropriate mounting hardware and
tighten. Refer to the figure to the left for mounting dimensions.
1.2
Connections
After the RHF is mounted, the input and output connections can be
made. The RHF is equipped with ¼” AAR style hardware for the
input and output connections. Connect the AC input to the
terminals marked “Φ1” and “Φ2”. Connect the DC output to the
terminals marked “+” and “–“ (observe proper polarity). Connect
the ground to the center ground terminal. See the figure below.
1.2.1 Charger Fail Alarm (located on the bottom of the unit)
The RHF unit is equipped with a single set of Form C dry type relay contacts for Charger
Fail Alarm. The Alarm will activate when the unit is unable to regulate the output voltage.
The alarm will activate also when the Low Current alarm will be enabled (in configuration
mode) and the charging current drops down to 0.5 amps. The connection for the alarm is
made by pushing in a small flat head screwdriver to open the contact point, then placing
the wire in and releasing.
