FEATURES

MOUNTING

refer to right- hand illustration

Power OFF host device;
Pull yellow slider out;
Fit Block slot downward onto DIN Rail;
Slide the Block to the left, but before joining the male and female mates, be sure that pin guards and pins are lined up correctly. Carefully slide the Block farther to the left to securely join the Block pins with host-device female mates;
Push yellow slider in, to secure Block on rail;
Secure Block(s) to DIN rail with cover, clamp, or other means provided with host device.

CONFIGURATION

ﬁrst connect the battery to the host device to power host device-shunt block system ReadyShunt settings are adjusted in the host device’s Morningstar LiveView Web Page. Refer to the Morningstar Website ReadyShunt full manual for details on how to connect to LiveView and access Installer Setup.

WARNING: Take great care to correctly conﬁgure or re-conﬁgure the ReadyShunt to match the installed shunt(s). Any deviation in ratings etc., e.g., Amps, Millivolts, polarity, branch type can cause severe battery damage.

CAUTION: Conﬁgure the ReadyShunt in the Morningstar LiveView webpage, FIRST, before wiring the ReadyShunt.
