Batteries give off combustible gases which can explode. A spark can cause the combustible gases to ignite. This can result in severe personal injury or death. Ensure proper ventilation for batteries that are in an enclosure. Follow the proper procedures in order to help prevent electrical arcs and/or sparks near batteries. Do not smoke when batteries are serviced. |

Battery Cabinet | |
The Temperature Monitor unit is placed inside the first battery cabinet that houses a battery circuit-breaker "QF1". Refer to Illustration 1.
- Open the unit cover.
- Break the self-cleaving seal on the base of the unit for insertion of the connecting cable.
- Install the unit in the cabinet using the self-adhesive sticker
Note: The temperature sensor must be placed at the top of the cabinet to work properly.
- Secure the using a 4 mm x 16 mm screw, nut, and washer combination.
Note: These hardware components are not supplied.
- Attach the cover.
- Tie the connecting cable to the cabinet ensuring that the cable does not pull on the monitor.

Secure the Temperature Monitor against a wall or any vertical support. Refer to Illustration 2.
- Choose a location near the batteries and away from drafts. Drafts may adversely affect the accuracy of temperature measurements.
- Using the holes provided in the base plate, screw the unit to the vertical support.
Note: Unless the connecting cable runs on the surface, break the knock-out in the unit base plate provided for cable entry.
- Secure the cable ensuring that the cable does not pull on the unit.

Connection to the Media Contacts 11 board. | |
- Referencing Illustration 5, connect the unit to the XR2 connector on the remote indications Media Contacts 11 board of the UPS cabinets
Use a shielded cable made up of two twisted telephone pairs with a conductor cross-section of at least 0.1 mm2. Ensure that the cable is not longer than 100 m (328 ft). Refer to Illustration 3.
Reference For the location of the Media Contacts 11 board, marked O refer to Operation and Maintenance Manual, "Component Description"
Note: For the parallel UPS configuration, the connections between cabinets may be made with a shielded cable made up of one or two twisted telephone pairs. In this configuration, the total length of all of the connecting cables must not exceed 100 m (328 ft).
- Connect the cable shield to ground pin 12 on connector XR2.
- Install the front and rear base plates of the cabinets.
Note: Clip the base plates to the feet of the cabinets unless the connecting cables are fed through these openings.
- Refit the terminal shields of the terminal blocks, switches, and circuit breakers.
