Before attempting to re-gas the Thermal Management System (TMS), ensure that the person undertaking the work is suitably qualified and meets local regulations for handling refrigerant.
Before work inside an E-Gen can be undertaken safely, it must be isolated to ensure there is no risk of electrical injury.
-
On the control panel side (front) of the unit, open the front door panel by inserting the key into the latches and unlocking, then depressing the latch buttons to release.
-
Lift the front door panel to gain access to the front panel, which contains the control panel switch, control panel, and MCCB switch.
-
Open the MCCB by turning the switch to OFF (O).
-
On the control panel, turn off the inverters by tapping OFF on the Home page.
-
Then, turn the control power switch to OFF (O).
-
On the connection side (rear), remove the single-phase or three-phase input cable.
-
Remove all output cables.
-
On the connection side (rear) of the unit, remove the rear panel by inserting the key into the latches and unlocking, then depressing the latch buttons to release.
-
Keep a hold of the rear panel as it fully detaches from the chassis, lifting to remove.
-
Identify the filter vent to gain access to the MSD fuse(s):
- The E-Gen150 and E-Gen300 have a single filter vent.
- For the E-Gen600, the MSD fuses can be accessed through the right filter vent.
-
Locate and loosen the four (4) Phillips-head screws securing the filter vent, then carefully lift out both the filter vent and the filter.
-
Identify the MSD fuse(s) attached to the Battery Management System (BMS):
- E-Gen150 and E-Gen300 have a single MSD fuse.
- E-Gen600 has two (2) MSD fuses.
-
Pull the locking collar to unlock the MSD fuse(s):
- On the E-Gen150 and E-Gen300, pull the locking collar toward you from the right side of the MSD fuse, then slide it to the left to unlock.
- On the E-Gen600, pull the locking collar toward you from underneath the MSD fuses, then slide upwards to unlock.
-
Pull the MSD fuse(s) straight out toward you and place on top of the unit with the connectors pointing upward.

❗
Ensure that the MSD fuse connectors remain clean and are not damaged while removed from the unit.

Once completed, the unit is now isolated.
-
On the control panel side (front) of the unit, identify the top three (3) 10mm Nyloc fasteners at the top corner on the left and right sides.
-
Loosen them sufficiently, but do not remove them entirely. Lower the hatch slightly to access any fasteners impeded by the hinges.
-
On the connection side (rear), identify the six (6) 10mm Nyloc fasteners. These are split into three (3) at the top corner on the left and right sides.
-
Loosen them sufficiently, but do not remove them entirely.
-
On top of the unit, insert the specialized removal tool into the Lifting Eye, and using a breaker bar or lever for additional torque, loosen and unscrew the Lifting Eye.
-
On the control panel side (front), locate and remove the three (3) or six (6) M5 Dome bolts on the front panel door(s) and swing open.
-
Unscrew the five (5) or ten (10) M6 Socket head bolts and remove the inverter and charger retaining bar(s).
-
Loosen the Phillips head screws securing the tops of the inverters and the charger.
-
Using a firm, steady pull, release the units from their seated position. Carefully slide each unit out one at a time and place in a safe location.

⚠️
Pinch Hazard. Hand placement is critical during removal. The clearance through the access hatch is extremely tight; ensure your fingers are clear of the housing edges.
</aside>
-
From inside the unit, locate and remove the twenty-four (24) 10mm Nyloc nuts (12 per side) that secure the top side trim plates.
- You will need to access the unit from both the control panel side (front) and connection side (rear). For the E-Gen600 you will also need to remove the left filter vent.
-
Lift away the top side trim plates to fully release the roof panel.
-
With two people, lift away the lid panel.
<aside>
⚠️
During removal, inspect and protect the O-ring around the lifting eye and the foam perimeter seals. If these are pinched or torn, they must be replaced to maintain the unit's weatherproofing.
