5. Battery Replacement Easy on

Environment

To replace battery simply remove body

for the one-touch installation type, and

remove battery lid for the installation

frame type.

6. Screw Terminals Designed for

Safety

Built in ﬁnger protection.

7. Panel Covers Replacable

(Standard color is ash gray.)

Change the panel design by replacing

with a black panel cover.

8. Conforms to IP66 Protective

Construction (Only installation frame

type.) (Front panel surface)

9. Input Methods

1) Non-voltage input method

2) Voltage input method

3) Free voltage input method

10. Backlight Type Added to Series

and Now 2-color Switchable (green/

red)

Easy viewing even in dark places and

switchable between green and red

(Voltage input type).

11. Compliant with UL, c-UL and CE

marking.

When installing the one-touch installation type model, make sure

that the installation spring does not pinch the rubber gasket.

To prevent the installation spring

from pinching the rubber gasket:

1. Set the rubber gasket on both

ends of the installation spring

(left and right).

2. Conﬁrm that the installation

spring is not pinching the rubber

gasket, and then insert and ﬁx the

installation spring in place from the

rear of the timer unit.
