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 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.
● The USA National Electrical Code (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
(one ground connection only)
