10.2.1 REPLACE BATTERY
A battery powers the real time clock on startup of the device.
When required, the battery can be replaced. The power supply module contains the battery. The older type is the RH/RL
power supply, while the newer type is the SH/SL power supply. To determine which procedure to use, check the power sup-
ply module or use the photographs here.
a) REPLACE BATTERY FOR RH/RL POWER SUPPLY
The power supply module contains the battery.
To avoid injury, ensure that the unit has been powered off for a minimum of three minutes
before replacing the battery.
Risk of fire if battery is replaced with incorrect type or polarity.
To replace the battery:
1.
Turn off the power to the unit.
2.
Wait a minimum of three minutes to ensure that there is no power to the battery.
3.
As outlined in the previous section, open the unit by sliding up the plastic latch on the right side of the front panel (stan-
dard front panel) or unscrewing the panel (enhanced front panel).
4.
For the standard front panel, it
needs to be removed in order to access the power supply module, which is typically in
the first slot on the left side and blocked by the hinge of the front panel. To remove the front panel, unscrew the bracket
on the front left side of the unit.
5.
Simultaneously pull the ejector clips at the top and bottom of the power supply module and remove the module.
6.
Unscrew the screw that attaches the metal cover to the module.
7.
Slide the metal cover away from the clips about 1 cm (1/4 inch) and remove the cover.
8.
Unclip the black plastic holder that keeps the battery in place. The plastic clips into the socket at the bottom on both
sides. Use a flat-head screwdriver if you cannot unclip the plastic with your fingers.
9.
Observe the + and - polarity of the battery and replace it with the same polarity as marked on the battery holder.
Replace the battery with the identical make and model. For example, do not use a rechargeable battery.
