Installation Guide for Guest Intelligent Charger

INSTALLING THE CHARGER

Note: The initial installation consists of (a) Choosing a mounting location, (b) mounting the charger, (c) making the DC connections, (d) selecting the appropriate battery chemistry, (e) making the AC connections to a receptacle that is protected by a GFCI breaker.

Choosing a Mounting Location

The charger should have at least eight inches of unobstructed area on all sides of the unit for effective cooling. The case of this charger may become warm during operation. For optimum performance, mount the charger in the vertical position (cables on the bottom), this will improve the convection cooling (airflow over the back of the charger). Mounting on its side or on a horizontal surface may cause the charger to slightly reduce amperage output due to the thermal protection built in. Do not install the charger on carpeted, upholstered, or varnished surfaces.

Mounting the Charger

  1. For the 16102, 16153 and 16202 use corrosion resistant 1-4 in bolts, backed by a flat washer, and secured to the mounting surface with a split-ring lock washer.
  2. Hold the charger to the mounting surface and mark the holes.
  3. Remove the charger and drill the mounting holes
  4. Align the charger and assemble the mounting hardware. Secure.

Making the DC Connections

Check polarity of the battery posts. The POSITIVE battery post usually has a larger diameter than the NEGATIVE post. Connect Red charger output wire to POSITIVE post, Black charger wire to NEGATIVE. See below diagrams for more details.

Setting Up the Battery Chemistry

Note- The battery chemistry needs to be set for each individual battery bank or charger output.

The battery chemistry indicators are defined as follows:

Flooded Lead Acid (FLA) and AGM Battery Mode Red LED

Safe Mode Blue LED

Gel Battery Mode Green LED

After you connect the DC cables of the charger to the batteries, the battery chemistry selection LED will illuminate (Safe Mode). At this point, you can toggle thru the different battery chemistry selections by pressing the pushbutton on the membrane panel for each specific output. Once AC is plugged in, this setting will be set by the micro into RAM and it will remember this setting until you interrupt both the battery power and AC power to the charger.

The battery chemistry selection LED will turn OFF 10 minutes after the batteries are first connected; this is called sleep mode. To recover from sleep mode press the battery chemistry selection button, this will turn ON the battery chemistry selection LED as long as AC power has not yet been applied.

The battery chemistry select LED will turn ON once AC has been applied to the charger and turn OFF 10 minutes after AC has been disconnected. If you do not know what type of battery you have, please choose the safe mode algorithm, which was developed for an unknown battery chemistry or application requirement.

Making AC Connection

After setting your battery chemistry selections for each output, connect the AC plug into an AC receptacle, which is protected by a Ground Fault Circuit Interrupter (GFCI) breaker.
