7.2 Installation of Batteries in Argus Tempest Power Systems
Verify that all battery breakers, DC circuit breakers, and fuses on the distribution panels are either
in the OFF position or removed. For each of the following steps, verify that the rubber terminal
caps / plastic covers are on and are completely covering the positive and negative terminal
connections.
Use a corrosion-inhibiting agent, such as NO-OX-ID “A”
¥, on all battery terminal connections.
1. Check the battery block voltage (typically >12.6V).
2. Unplug Anderson connectors on all battery string cables to disconnect DC output bus bars from system.
3. Slide the battery blocks onto the battery trays starting at the bottom (four per tray) – see previous photos.
NOTE: The enclosure must be mounted before installation of the bottom tray of batteries may be completed.
4. Ensure that the battery output cabling will reach the [+] and [–] terminals of the series battery string and that
the batteries are oriented correctly for easy installation of the inter-unit “series” connectors.
5. Remove any NO-OX-ID “A”
¥ grease from battery terminals.
6. Burnish terminal posts with a non-metallic brush, polishing pad or 3M Scotch Brite
¥ scouring pad.
7. Apply a light coating of NO-OX-ID “A”
¥ grease to the terminal posts.
8. If lead plated inter-unit connectors are used, they should also be burnished and NO-OX-ID “A”
¥ grease
applied as above. Install the inter-unit connectors.
9. Connect the batteries to the pre-installed cables.
10. Install in-line battery fuse on one battery terminal inter-unit connector per string (two fuses per shelf for a 24V
configuration); for example:
NOTE: Sequence: battery terminal, fuse, inter-unit connector, insulating shoulder washer, flat/split washer, and bolt.
Mounting bolt torque is 8.4Nm +/- 0.5Nm maximum. Exceeding this value may damage the insulating shoulder
washer or fuse or both. Refer to battery fuse kit instructions for the specific batteries used.
11. Install battery temperature probe to the negative terminal of two
center batteries, one on each tier, in the same enclosure.
12. Repeat the above installation procedure for each shelf and battery
string.
13. After all battery connections are completed, torque per battery
specifications; for example:
Description Recommended Torque Value
GNB battery bolts 100 in-lbs
East Penn Deka battery bolts 45 in-lbs
Battery in-line fuse
75 in-lbs. or battery torque
(whichever is less)

installation requirements) Table B–Sample torque specifications
14. Verify polarity and voltage at each battery cable (Anderson connector contacts). Do not connect yet!
NOTE: See system startup procedure before connecting batteries online.
After assembly, batteries should be numbered and “as received” readings should be taken, such as, battery
voltage and temperature. Refer to manufacturer's literature for guidelines.
See following table for typical maintenance report.
