3. Installation
WARNING: DC (PV) INPUT NOT ISOLATED FROM BATTERY
CIRCUIT
CAUTION: FOR PROPER TEMPERATURE COMPENSATION
THE AMBIENT CONDITION FOR CHARGER AND BATTERY
MUST BE WITHIN 5°C.
3.1. General
● Mount vertically on a non-flammable substrate, with the power
terminals facing downwards.
● Mount close to the battery, but never directly above the
battery (in order to prevent damage due to gassing of the
battery).
● Improper internal temperature compensation (e.g. ambient
condition battery and charger not within 5°C) can lead to
reduced battery lifetime.
● Battery installation must be done in accordance with the
storage battery rules of the Canadian Electrical Code, Part I.
● The battery connections (and for Tr version also PV
connections) must be guarded against inadvertent contact (e.g.
install in an enclosure).
3.2 Grounding
● Battery grounding configuration: the charger can be
configured as a positive- or negative-ground system.
Note: apply a single ground connection (preferably close to the
battery) to prevent malfunctioning of the system.
● Chassis grounding: A separate earth path for the chassis
ground is permitted because it is isolated from the positive and
negative terminal.
● NEC requires the use of an external ground fault protection
device (GFPD). These MPPT chargers do not have internal
ground fault protection. The system electrical negative should be
bonded through a GFPD to earth ground at one (and only one)
location.
● The charger must not be connected with grounded PV arrays.
WARNING: WHEN A GROUND FAULT IS INDICATED,
BATTERY TERMINALS AND CONNECTED CIRCUITS MAY BE
UNGROUNDED AND HAZARDOUS.
