Engineering Data

■ AMBIENT OPERATING TEMPERATURE AND CARRY CURRENT

H5L

The upper limit of the ambient operating temperature must be derated when a large carry current is being applied. This case occurs when both circuits are energized simultaneously.

Dimensions

Unit: mm (inch)

■ TIMER

60°C (140°F)

55°C (131°F)

When both circuits are energized simultaneously

50°C (122°F)

40°C (104°F)

Maximum ambient operating temperature

Carry current AC/DC (A)

■ PROTECTIVE COVER

The hard plastic cover prevents accidental resetting. It also shields the front panel from dirt and water. The cover is intended for use in areas where unusual service conditions do not exist.

H5L

If operating conditions exceed the noise values at right, connect a surge absorber to prevent malfunction or damage to the timer. This is especially important when inductive loads are being switched by the timer.

Installation

■ WIRING Power Supply

For panel mounting

Noise voltage: 2 KV Pulse width: 100 ns Rise time:1 ns

For track and surface mounting

Wire the H5L timer from the rear once the unit is mounted in the panel.

Output Circuits

Perform wiring so that the potential across the output contacts is the same. This prevents short-circuiting of the contacts. Refer to the connections chart above for terminal numbers.

Wire the H5L timer from the front when the unit is track or surface mounted.

1. Loosen the screw above the "cycle" key on the left front.

2. Slide the upper part of the housing upward about 15 mm (0.59 in).

3. Step 2 exposes the terminals. Perform the wiring.

4. Slide the upper part of the housing to the original position, then tighten the screw.
