8 Replacing the battery
Batteries must only be replaced by original batteries of type G8610070000 or G8610080000 supplied
by Wigersma & Sikkema. It is permitted to replace the battery in a potentially explosive atmosphere.
Put UNIGAS 300 into sleep mode through menu item 10 prior to replacing the battery. UNIGAS 300
can remain operational in sleep mode for about 17 s without battery (for safety reasons the display will indicate
10 s). During sleep mode, UNIGAS 300 will not carry out any conversion. The clock does keep running. After
sleep mode UNIGAS 300 will activate itself and all functions will become active again.
If replacing the battery takes longer than this sleep mode period, UNIGAS 300 will shut down. The moment
UNIGAS 300 gets powered again, UNIGAS 300 will start up with the most recent backup data. UNIGAS 300
makes a backup every 5-min interval, so the information will not be older than 5 min. The power failure will be
logged in status register 1 and the clock will have to be set again.

battery within easy reach.
•
Unscrew the two bolts on the front of UNIGAS 300 until the bolt heads are roughly level with the
