main switch is set to the “discharge” position. The ICL may heat to over 100
o
C immediately
after the gun is shut down but quickly cools within the span of a few minutes.
The fuse, main switch and firing mode selector will be discussed in the sections below:
2.3 Main fuse
The main fuse of the EMG-01B is a 40A automotive fuse which acts as a protection
against certain types of over-current and also serves as to isolate the battery from the
electronics for short term storage of the gun.
The EMG-01B uses a different startup procedure than the EMG-01A which allows the
gun to be shut down quickly and powered on easily without the small sparks that plagued the
fuse contacts of the EMG-01A. HOWEVER – it is of the utmost importance that the user never
inserts the fuse with the power switch set to the ON position. Doing so will place the entire
switched load of the gun onto the fuse contacts which will superheat, convert to plasma and
expand rapidly- resulting in damage to the fuse contact pads, the fuse itself, and possibly: the
user’s fingers as well as the gun’s switching electronics. It is for this reason that an additional
warning to this effect is placed on page 1 of the manual. As with all electronic devices: make
sure the power is switched off before inserting the fuse.
2.4 Main switch
The main switch of the EMG-01B controls both the power electronics and the DCL. It
has two modes: Discharge and ON.
When the switch is placed in the ON (REARWARD) position, the battery will be
connected to the main electronics of the gun and the capacitors will be commanded to charge
- ALWAYS ENSURE THE POWER SWITCH IS SET TO THE DISCHARGE (FORWARD) POSITION
BEFORE INSERTING THE FUSE OR BATTERY.
- NEVER INSERT THE FUSE WITH THE SWITCH IN THE ON (REARWARD) POSITION.
- Inserting the fuse with the power switch in the CHARGE (rearward facing) position will
cause high amperage flashover resulting in damage to the gun, shock and/or burns to the
user.
- Always ensure the main switch is set to the DISCHARGE (FORWARD) position before
removing the fuse.
- The Main Fuse may be removed as an alternative to fully removing the battery for short
term storage of the gun.
