Installation
The MSI-4260 features a heavy duty, cast aluminum enclosure rated at NEMA Type 4 IP 66. It installs easily by hanging it on a
crane using properly sized shackles.
Refer to the Crane Scale Safety and Periodic Maintenance Manual (PN 153105) for safe loading and rigging
guidelines when installing the model MSI-4260.
Regular maintenance inspections of the lifting system should be performed to ensure safety. Pay particular
attention for signs of stress on any element in the load train.
Use the appropriate interface hardware for the capacity of the scale.
• If the interface hardware does not fit properly, Rice Lake Weighing Systems can supply the MSI-4260 with oversize lifting
eyes or shackle interfaces.
• If the crane hook is too large to fit in the lifting eye with single point interface, then install the scale using adaptive rigging.
• If multiple attachments are needed, use a shackle or ring to attach the multiple lines to keep a single point attachment to
the scale.
Using an oversize shackle or hook to interface with the MSI-4260 can cause off center loading and stress points
that will reduce the life of the lifting eye or hook.
Single point attachments are necessary to ensure the safety and accuracy of the scale system.
2.1 Unpacking
When unpacking the MSI-4260, ensure that all assembly parts are accounted for. Check the MSI-4260 for any visible damage.
If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately. If the MSI-4260 must
be returned, it must be properly packed with sufficient packing materials. Whenever possible, use the original carton when
shipping the unit back.
2.2 Battery Pack
The MSI-4260 is powered by a 12V Sealed Lead Acid (SLA) rechargeable battery. This battery will operate for up to 100 hours
(depending on LED brightness setting) before requiring recharging.
Charging time for a completely discharged battery is up to eight hours. A spare battery pack is recommended to keep the MSI-
4260 in continuous operation.
To obtain maximum service life from batteries, store between -4°F and 122°F (-20°C and +50°C).
Stored batteries should be recharged every three months. The battery is fully charged when the status indicator
on the battery charger is flashing.
2.2.1 Battery Life
The battery life of the MSI-4260 depends on a number of factors:
• The brightness of the LED display and number of segments lit
• The amount of RF activity
• The age of the battery
• The condition of the SLA battery.
In order to conserve battery life, the MSI-4260 includes the following features.
• Automatic Power Off Mode — Senses no activity after the set amount of minutes and turns the scale off
• Automatic Sleep Mode — Dims the display after a set amount of minutes of no scale activity
The MSI-4260 automatically turns off when the SLA battery drops to approximately 10.5V. Recharge the battery when this
happens, SLA batteries benefit from frequent recharging and can be recharged when it still has available life.
Due to the maintenance discharge imposed on the battery by the MSI-4260 electronics, do not store the MSI-4260 with the
battery inside. Remove the battery if it will not be used for more than two weeks.
Leaving a discharged battery in the scale, which has a maintenance battery drain, can result in a deep
discharged battery which will shorten its service life.
*If the scale is in continuous use, a fully charged spare battery is recommended. Replace the drained battery as close as possible to the low
battery warning.
*SLA batteries that have not been deep discharged should withstand 500 to 1500 charging cycles.
*Low battery warning annunciator indicates about two to four hours of additional use before MSI-4260 powers off.
*If MSI-4260 is not going to used again soon, remove SLA battery to prevent deep discharge while unit is in storage.
*Recycle the battery at an authorized recycling center when the average life drops to 20 hours or less.
