5. Installation
5.1. Mounting
Before mounting, the following aspects should be considered to identify/provide a suitable and safe location:
Install the charger in a location with good natural airflow/ventilation; in case airflow is a restricted, consider adding a cooling fan.
Ensure there is sufficient unobstructed space around the charger; a minimum clearance of 100mm above and below is recommended.
Install the charger on a non-flammable substrate and ensure there are no heat-sensitive items in the immediate vicinity; it is normal for the charger to become hot during operation.
Install the charger in a location where it is protected from environmental conditions such as water, high moisture and dust, and also located well away from any flammable liquids or gasses.
Do not install or place/operate the charger on top of the battery, directly above the battery, or in a sealed compartment with the battery; batteries can emit explosive gasses.
Do not cover or place any other items on top of the charger.
Select and use screws with a pan/flange head (do not use screws with a countersunk/tapered head), and a screw thread outer diameter well matched to the mounting hole/slot internal diameter (~5mm max OD to provide a clearance fit).
Refer to the drawing below for mounting dimensions:
5.2. Wiring
Connect the DC power cabling to the battery/batteries or DC system distribution bus - follow the instructions relevant to the installation type.
For hardwired installations, or when charging a battery outside of a vehicle/installation:
Ensure that the DC system is shut down (all DC loads and charge sources off/isolated) prior to disconnection of any existing battery / DC system distribution bus cabling and connection of the charger to the battery terminals / DC system distribution bus.
Connect the positive DC cable (red insulation) to the positive (+) terminal and the negative DC cable (black insulation) to the negative (-) terminal connection; ensure that the cable connection polarity is correct.
Torque all wiring termination hardware to manufacturers torque specifications using a suitable torque wrench and socket / screw driver bit.
For temporary installations when charging a battery installed within a vehicle, and the negative (-) battery terminal is grounded to the vehicle chassis (conventional):
Connect the positive DC cable / battery clamp (red insulation) directly to the battery positive (+) terminal first.
Then connect the negative DC cable / battery clamp (black insulation) to a suitable grounding point on the vehicle chassis (not directly to the negative battery terminal).
When disconnecting the charger, disconnect the DC cables / battery clamps in reverse of the connection order.
For temporary installations when charging a battery installed within a vehicle, and the positive (+) battery terminal is grounded to the vehicle chassis (unconventional):
Connect the negative DC cable / battery clamp (black insulation) directly to the battery negative (-) terminal first.
Then connect the positive DC cable / battery clamp (red insulation) to a suitable grounding point on the vehicle chassis (not directly to the positive battery terminal).
When disconnecting the charger, disconnect the DC cables / battery clamps in reverse of the connection order.
