SIERS 2.0 Siemens Integrated Electrical Racking System Instruction Manual
The following steps describe the operation sequence
using the Portable HMI to rack an auxiliary truck.
1. Place the portable carrycase to the appropriate
location outside of the arc-flash boundary for
energized switchgear or up to 30 feet from
the switchgear.
2. Plug in the PWR/control cable from the portable
case into the 16-pin receptacle on the side of
portable carrycase and the other end of cable
to the receptacle located on the low voltage
compartment for the corresponding circuit
breaker compartment.
IMPORTANT: When first time operating SIERS,
start with auxiliary truck in the DISCONNECT
position. On a de-energized lineup use the
manual racking crank provided with the
accessories to rack the auxiliary truck to the
DISCONNECT.
3. Starting with the auxiliary truck in the
DISCONNECT position in the auxiliary
compartment.
4. Follow the relevant instruction manual for
GM-SG, or GM-SG-AR switchgear.
a. The auxiliary truck is now in the DISCONNECT
position.
b. The solid green indication (for DISCONNECT)
on the HMI display will illuminate.
5. Ensure the auxiliary compartment door is closed
and latched. If the door is not closed, SIERS will be
disabled; and alarm will indicate on the HMI screen.
6. Ensure the CBM 1 and CMB 2 miniature circuit
breakers in the portable carrycase are switched
ON to turn on HMI touchscreen interface.
IMPORTANT: Before racking the CPT truck in
the CONNECT or DISCONNECT position, the
secondary moldcase circuit breaker must be
OPEN, disconnected to flow of secondary
current from the CPT.

7. Before racking an auxiliary truck with Control
Power Transformer (CPT) or fuse roll-out truck for
a CPT, the secondary molded case circuit breaker
(MCCB) must be opened, and the key interlocked.
Note: This step is not required for voltage
transformer (VT) truck.
8. After step 7 above is performed, SIERS will allow
the auxiliary truck to be racked.
9. When the auxiliary truck begins to move, the
green indication (for DISCONNECT) will turn off.
10. When the auxiliary truck reaches the CONNECT
position, the red indication (for CONNECT) will
turn on.
a. The auxiliary truck is now in the CONNECT
position; for CPT or fuse truck, the secondary
molded-case circuit can be turned on. Follow
the instructions in the relevant GM-SG or
GM-SG-AR instruction manual.
11. To rack a CPT or fuse truck from CONNECT to
DISCONNECT, the molded-case secondary circuit
breaker must be opened and interlocked with
the kirk key features.
12. For CPT or fuse truck, once the molded-case
secondary molded-case circuit breaker is opened
(turned off) and interlocked, SIERS can be used
to rack the CPT or fuse truck to the DISCONNECT
position.
13. Touch DISCONNECT on the HMI display.
The auxiliary truck will move towards the
DISCONNECT position.
14. The red indication (for CONNECT) will turn off.
15. Once the auxiliary truck reaches the
DISCONNECT position, the green indication (for
DISCONNECT) will turn on.
