3. Installation

WARNING: DC 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 surface, with the power
terminals facing downwards. Observe a minimum clearance of
10 cm under and above the product for optimal cooling.
● 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.
We recommend using a direct battery voltage sense source
(BMV, Smart Battery Sense or GX device shared voltage sense)
if larger temperature differences or extreme ambient
temperature conditions are expected.
● 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 or install the optional WireBox).
Tr models: use flexible multistranded copper cable for the battery
and PV connections: see safety instructions.
MC4 models: several splitter pairs will be needed to parallel the
strings of solar panels. Do not exceed the maximum current
rating of 25A per connector pair
