Intermatic ug30 modular ユーザーズマニュアル

1.

INSPECT the shipping carton for damage or signs of mishandling before opening.

2.

Remove the unit and the mounting brackets from the shipping carton.  Inspect for obvious shipping damage.

3.

If any shipping damage is observed, immediately file a claim with the shipping agency and notify your distributor.

1.

TEST and verify system voltage to assure proper selection of the Surge Protection Device (SPD) in accordance 
with the wiring diagrams shown on page 2. Turn off the electric power to the panel. 

2.

CONFIRM that the Surge Protection Device is the proper voltage configuration for this installation. Refer to the 
installation diagrams for additional information.

3.

SELECT a location to mount the UG Modular cabinet. Mount as close as possible to the electric panel or individ-
ual piece of equipment to be protected. The UG Modular device should be mounted on a flat vertical surface that 
can support the weight of the device. Consideration should be given to the available knockout positions in the 
panel when deciding where to locate the UG Modular device. All wire leads should be kept as short as possible to
insure optimum operation.  

4.

The internal 100 KAIC fuses are the prime current protection devices for the UG Modular device. While the lead 
wires may be connected to either a bus bar or a multi-pole breaker, installation to a 30 amp breaker with the 
appropriate number of poles is preferred. Circuit breakers will not trip from transient surge activity due to their 
inherent slow response.

1.

Attach the upper and lower mounting rails to the UG Modular Cabinet using the screws provided.  

2.

Pre-drill holes in the surface on which the UG Modular Cabinet  will be mounted.  Use at least four (4) appropriate
size mounting screws or bolts.  

3.

Select and remove the proper size knockout from the UG Modular Cabinet cabinet. Install conduit, sealtite or 
other proper wire protection between the panel and the UG Modular device.  

1.

For installations using less than three feet of wire for each lead, use 10 AWG stranded wire. 

2.

Measure and cut all leads to proper length, keeping in mind that leads should be as short and straight as possible.

3.

Tape all wires together to minimize inductive coupling. 

4.

Route the wire lead bundle through the conduit to the panel.  

5.

Connect the GROUND (green) lead to the ground bus in both the UG Modular unit and the electric panel. 

6.

If used, connect the NEUTRAL (white) to the neutral fuse terminal in the UG Modular unit  and the neutral bus in 
the electric panel. If installing at the main distribution panel, the neutral and ground leads could terminate at a 
common bus bar in the panel.  

7.

Connect the phase leads to the fuse block terminals in the UG Modular unit. Connect each phase lead to the 
appropriate breaker or bus connections in the electric panel. NOTE: For HIGH LEG DELTA, make certain that the 
high leg is connected to the middle fuse terminal position.(Refer to Figure 3)  For GROUNDED PHASE DELTA, 
make certain that the grounded phase is connected to the middle fuse terminal position in the UG Modular 
unit.(Refer to Figure 4)

8.

CHECK  all connections for tightness or torque. Observe the suggested torque values published by the device 
manufacturer when breakers or disconnect switches are used.
