## **FEATURES** 

## **1. Compact to save panel space** 

The 24 × 48 mm hour meters are just half the DIN 48 × 48 standard size. They help save the panel space. 

## **2. Reset button** 

The hour meters can be reset to zero (TH64). 

The measurement can be displayed from 0.1 hour up to 99999.9 hours (TH63). The dial size is the same as that of 48 × 48 DIN size hour meters (TH14 and TH24 series). 

## **4. Easy to install** 

The flat terminals (#187) are used for easier wiring. There is no need to undo the lock spring. 

## **5. High-performance sync motor with 50/60 Hz selector** 

The noise-resistant, accurately turning motor is employed to provide for longer period of measurement. The power frequency can be selected for 50 or 60 Hz. 

## **6. Rotary indicator** 

NAiS’s original moire pattern mechanism helps watch the rotary indicator for quick monitoring (one turn every 72 seconds). 

## **7. CE marking** 

The hour meters satisfy EMC directives (EN50081-2/ EN50082-2) and low-voltage directives (EN61010-1). 

## **TYPICAL APPLICATIONS** 

Management of small generators and food processing machines; hour counting for leased equipment; maintenance management of various equipment, etc.

## **MOUNTING** 

1. Cut a 22.2+0.60 × 45+0.60 mm (.874 +.0240 × 1.772 +.0240 inch) opening in the panel. 

2. Swing the mounting spring to the rear of the hour meter and fit the hour meter into the panel opening. (There is no need to detach the mounting spring from the hour meter.) If the panel is 5 to 9 mm .197 to .354 inch thick, move the mounting spring to the other hole toward the rear of the hour meter. 

3. Swing the mounting spring to the front of the hour meter to secure the hour meter to the panel. 

4. Wire the supplied quick connectors and connect to the hour meter. Be sure to use the supplied insulating sleeves to cover the connectors.
