Installation

Using Trim Pieces
Ramp Trim with Yellow PVC Cover: UMRT4/UMRT8
Secures the edges of the Safety Mats to the floor.
It is composed of two parts with an aluminum base and a PVC Cover.

In this case, the perimeter of the Safety Mat is about 4 m and the following pieces are required:
The example above consists of the following components:
UMMA-1000-1000 Safety Mat : 1 piece
UMRT4 Ramp Trim with Yellow PVC Cover (1.22 m) : 4 pieces
UMOC Molded Outside Corner : 4 pieces

Joining Trim: UMJS4/UMJS8
The Joining Trims join the Safety Mats when two or more Safety Mats
are being combined.
In addition to joining the Safety Mats, the Joining Trims preserve the
Safety Mat’s sensitivity at the joints.

Aluminum Ramp Trim: UMAL
Secures the edges of the Safety Mat to the floor.
The Aluminum Ramp Trim is hollow, so cable can be routed through it.

Molded Outside Corner: UMOC
Used together with the Ramp Trim with Yellow PVC Cover (UMRT4/ UMRT8) to secure the external corners of the Safety Mats to the floor.

Molded Inside Corner: UMIC
Used together with the Ramp Trim with Yellow PVC Cover (UMRT4/ UMRT8) to secure the internal corners of the Safety Mats to the floor.

Note:

The Aluminum Ramp Trim or Ramp Trim with Yellow PVC
Cover must be cut to fit the size of the Safety Mats being used. Furthermore, when the Safety Mat’s wiring is being routed through the Aluminum Ramp Trim or Ramp Trim with Yellow PVC Cover, it will be necessary to cut or notch the Aluminum Ramp Trim or Ramp Trim with Yellow PVC Cover for cable access. Refer to UMA Safety Mat User Manual (Man. No. Z375-E1) for details on cutting or notching the Aluminum Ramp Trim or Ramp Trim with Yellow PVC Cover.
The Joining Trim must be cut to fit the size of the Safety Mats being used.
The Ramp Trim with Yellow PVC Cover and Molded Corner must be anchored to the floor to secure the Safety Mats. It is also necessary to drill holes in the Trim to anchor it. Refer to UMA Safety Mat User Manual (Man. No. Z375-E1) for details on drilling holes in the Trim and Molded Corner

Safety Mat Configuration
The Safety Mats are secured by anchoring the Ramp Trim with Yellow PVC Cover and Molded Corner to the floor. Before ordering, confirm the number of Ramp Trim with Yellow PVC Cover and Molded Corner pieces that will be needed.
Example 1: Using a Single Safety Mat

In this case, the perimeter of the Safety Mat is about 8 m, the joint between the Safety Mats is 2-m long, and the following pieces are
required:
The example above consists of the following components:
UMMA-1000-1000 Safety Mat : 3 pieces
UMRT4 Ramp Trim with Yellow PVC Cover (1.22 m) : 8 pieces
UMJS4 Joining Trim (1.22 m) : 2 pieces
UMOC Molded Outside Corner : 5 pieces
UMIC Molded Inside Corner : 1 piece

Connection Examples of Safety Mat and Controller
Using a Single Safety Mat
Connecting a 1-cable Mat (UM@@A-@-@-1) to a MC3 Safety Mat Controller or SCC-1224A Safety Mat/Edge Controller.

Using Multiple Safety Mats

Connecting three 2-cable Mats (UM@@A-@-@-2) to a SCC-1224A Safety Mat/Edge Controller
Connecting three 2-cable Mats (UM@@A-@-@-2) to a MC3 Safety Mat Controller
UMA-CBL-3PMM-M8-0.15M UMA-CBL-3PCF-M8-@M
M8 3-pin single connector cable
M8 3-pin male-male extension cable

When an MC3 is used, the total cable length is up to 100 m and up to 12 Safety Mats can be connected (up to 10 m2 in total).
When an SCC-1224A is used, the total cable length is up to 25 m and up to 10 Safety Mats can be connected (up to 10 m2 in total). For the 1-cable type of UMA Safety Mat (UM@@A-@-@-1), the total lone length of cable must be calculated by multiplying the total length of the cables used by two.
The required accessories vary depending on the mat configuration and layout.
